Description

  The present invention relates to a program design apparatus for designing a program using a state transition diagram.

A state transition diagram is a diagram that expresses how an object changes its state due to various events.
As a notation of the state transition diagram, there is a definition of UML (Unified Modeling Language) which is a language for executing unified modeling (Non-patent Document 1).
And as a means of improving development efficiency by reusing input data, there is a technology that saves frequently used state transitions in the state transition diagram in a database, calls it, and pastes it in the state transition diagram is there. (For example, Patent Document 1)
If the notation of UML is used as the notation of the state transition diagram, each state is represented by a rounded rectangle, and the state transition is represented by an arrow connecting the rectangles. In addition, a small circle is used as a representation of the initial state, and the completed state is represented by a double circle in which the inner circle is painted black. When a state performs event processing internally, it encloses a rectangle vertically with a solid line and lists events and their actions separated by “/” below them.
When a state has two or more parallel states, it is written along with a rectangle indicating the state vertically separated by a dotted line.
An arrow indicating a transition may have an event name serving as a trigger, a guard indicating whether or not to make a transition determination, and an action indicating processing at that time. The event name and action are expressed by connecting with “/”, and the guard is expressed by enclosing the conditional expression with [and]. A transition occurs when the guard conditional expression is true, and no transition is made when it is false.

Patent Document 1 shows a screen transition pattern that is frequently used in a screen transition diagram stored in a database, which is called and reused. Here, a frequently used screen transition pattern is: A specified area of the screen transition diagram specified by the input device is registered in the database, and the screen transition pattern is reused by entering the part name of the screen transition pattern and searching the database using this part name as a key. This is done by extracting the relevant screen transition pattern and copying it to the designated location in the screen transition diagram.
In addition, in the UML notation, references to state transitions called submachines are nested and described as separate layers, so that frequently used state transition definitions are gathered in one place and the reuse of input data is promoted. .

UML Reference Manual (ISBN4-89471-267-9), James Lambeau et al., Pp61-72 JP-A-7-219754 (pages 3-8, FIG. 2)

When writing a state transition diagram in the form of a diagram defined in UML, similar state transitions may appear in the diagram many times, and the same thing may have to be written many times. As a result, there are problems of writing the same thing over and over, problems such as making the figure more complex than necessary and lacking readability, and inability to express the intended figure simply on a two-dimensional drawing. There is a problem that the same correction must be made to a plurality of parts in the figure at the time of correction.
As a result, the cost related to software design has become large.
Patent Document 1 shows that a screen transition pattern that is frequently used in a screen transition diagram is stored in a database, and is recalled, copied, and reused. It is necessary to input the screen transition diagram area and screen transition pattern name by the input device at the time of reuse, especially when copying, it is necessary to correct all the copies, and it cannot be denied that it is difficult to use It was.
The state transition diagram has not only the surface meaning as a diagram, but also attributes and actions reflecting the actual program, parallel state transitions, etc., in the elements in the diagram and their connection / inclusion relationships. Therefore, the implications cannot be handled only by graphic processing.

  The present invention has been made to solve the above-mentioned problems, and by disassembling and synthesizing the data of the state transition diagram, the data of the common part is unified, and the trouble of writing the same thing over and over again. The purpose of the present invention is to obtain a program design apparatus that does not require the same correction to be repeated many times when the common part is corrected.

  In the program design apparatus according to the present invention, a state transition display editing apparatus for displaying a state transition diagram to the user and editing the state transition diagram by the user, common part data storing common part data frequently appearing in the state transition diagram Storage device, state transition data storage device storing state transition data of state transition diagram excluding common portion data, common portion data application position storage device storing application position information of common portion data to state transition data, this common portion Common part data stored in the common part data storage device in the state transition data stored in the state transition data storage device using the application position information of the common part data to the state transition data stored in the data application position storage device Are synthesized by a synthesis device that displays the synthesized state transition diagram on a state transition display editing device, and a state transition display editing device. The state transition diagram is decomposed into common part data, state transition data, and application position information of the common part data to the state transition data. The state transition data storage device includes a disassembly device that stores application position information of common part data to state transition data in the common part data application position storage device.

  As described above, the present invention is a state transition display editing apparatus that displays a state transition diagram to a user and edits the state transition diagram by the user, and common portion data that stores common portion data that frequently appears in the state transition diagram. Storage device, state transition data storage device storing state transition data of state transition diagram excluding common portion data, common portion data application position storage device storing application position information of common portion data to state transition data, this common portion Common part data stored in the common part data storage device in the state transition data stored in the state transition data storage device using the application position information of the common part data to the state transition data stored in the data application position storage device , And the state transition edited by the state transition display editing device and the composition device that displays the combined state transition diagram on the state transition display editing device The figure is decomposed into common part data, state transition data, and application position information of common part data to state transition data, and the decomposed common part data is stored in the common part data storage device and the state transition data is stored in the state transition data. Since the apparatus is equipped with a decomposition device that stores application position information of common part data to state transition data in the common part data application position storage device, common part data that frequently appears in the state transition diagram can be unified, This eliminates the need to write the same thing over and over, and eliminates the need to repeatedly apply the same correction to the diagram when the common part is corrected.

Embodiment 1 FIG.

The state transition display editing device 2 presents the data of the state transition diagram synthesized by the synthesizing device 11 to the user and transmits the user's editing operation to the disassembling device 12. The state transition data storage device 3 holds state transition data representing a state transition diagram edited and browsed by the user. The common part data storage device 4 stores common part data such as state transition patterns, state (state) attributes, and actions that are frequently used in one state transition diagram and are commonly used. The common part data application position storage device 5 applies the common part data held by the common part data storage device 4 to which state of the state transition data of the state transition data storage device 3 to synthesize the state transition. The common part data application position data is held. The common part display selection mechanism 6 switches whether the synthesizing device 11 synthesizes common part data.

In the first embodiment, state transitions that occur frequently are used as common part data, separately from the state transition data of the state transition diagram, and the state transition diagram data includes state transition data, common part data, and common part data. Data is expressed by common part data application position data indicating where in the state transition data is to be combined, each data is then combined and presented to the user, and the user's editing result is decomposed and stored into each of the above data By doing so, the data of the common part can be unified. For this reason, there is no need to write the same thing over and over, and a program design apparatus is obtained that does not require the same correction to be repeated over and over when the common part is corrected.
The problem of readability due to the complexity of the figure is solved by adding a common part display selection mechanism 6 for switching whether to synthesize common part data.

In addition, as a representation of the initial state, a filled small circle mark as shown on the left side of 201a in FIG. 2 is used, and the completed state is represented by a double circle obtained by painting the inner circle black as shown on the right side of 201a in FIG. To do. When a state performs event processing internally, it encloses a rectangle vertically with a solid line and enumerates events and their actions separated by “/” below (see FIG. 3).
When a certain state has two or more parallel states, as shown in FIG. 2, rectangles indicating the states are vertically separated by dotted lines.
An arrow indicating a transition may have an event name serving as a trigger, a guard indicating whether or not to make a transition determination, and an action indicating processing at that time. The event name and the action are described by being connected with “/”, and the guard is expressed by enclosing the conditional expression with [and] ([n <3] in FIG. 10).

FIG. 15 is a diagram showing a result of addition to the common part data by the editing operation of the program design device according to Embodiment 1 of the present invention.

Next, the operation will be described.
The state transition data storage device 3 holds data representing a state transition diagram edited and browsed by the user. What we have is a list of states that represent states, data indicating what events are received and how they are transitioned, and what actions each state takes in response to what events are received And the guard condition that blocks the action and transition that each transition causes at the time of transition. Each element is labeled and named. It also has data such as a display position indicating how the state transition display editing device 2 displays each element.

  The common part data storage device 4 holds state transition patterns, state attributes, actions, and the like that are commonly used in one state transition diagram. This is a definition of a common parallel state that exists in states that are separated graphically, such as 201a and 201b in FIG. 2, or many states have in common as shown in FIG. A set of events and actions. In order to synthesize the common part data with the state, the common part data has a virtual synthesis target state. It also has display position (relative position) data indicating how to display these common data after combining, and data such as display priority when combining a plurality of common data in one place. The attribute in the common data can include a tag indicating that it is a variable part, and this part is rewritten by the synthesizer 11. For example, as shown in FIG. 4, a method of expressing the name of the variable part by enclosing it with {} can be considered.

  The common part data application position storage device 5 applies the common part data held by the common part data storage device 4 to which state of the state transition data of the state transition data storage device 3 to synthesize the state transition. The common part data application position data indicating this is held. The common part data application position storage device 5 has data indicating the destination state to be applied and common part data to be applied. The common part data application position storage device 5 also holds information on how to rewrite a variable part of the attributes in the common data.

The synthesizing device 11 acquires the application position of which common part data is applied to which state of the state transition data from the common part data application position storage device 5, and the state transition data acquired from the state transition data storage device 3 The common part data acquired from the common part data storage device 4 is combined in the order according to the priority order. The data synthesized by the synthesizing device 11 is transferred to the state transition display editing device 2, and the data becomes the object of browsing / editing.
Whether each element of the data of the synthesized state transition diagram is newly added with a tag, is the data acquired from the state transition data storage device 3 as it is, or is it modified by the synthesis of the common part data? It is possible to distinguish whether the data is added by the synthesis of the common part data. In the case of a data tag by synthesis, data indicating which common unit data application position storage device 5 has synthesized the data is also added. In addition, the operation of applying the data of the common part data application position storage device 5 to the variable part of the attribute in the common data is also performed.

Next, the operation of the synthesizing apparatus will be described using the flowchart of FIG.
It is determined whether or not there is unprocessed common part data in the common part data storage device 4 (step 21). If there is no unprocessed common part data, the process ends. If there is, unprocessed common part data is extracted (step 22). Next, it is determined whether or not there is uncombined common part data application position data in the common part data application position storage device 5 (step 23). If there is no common part data application position data, go to step 21; One piece of data is extracted and searched from the state transition data (step 24). Next, the common part data is combined with the place obtained by the search in step 24 (step 25).

When the state transition diagram is edited by the user in the state transition display editing device 2 and the edited part is the data from the state transition data storage device 3 and is not combined, the disassembly device 12 corresponds. Data in the state transition data storage device 3 is updated.
If the edited part is a part added by the synthesis of the common part data, the data in the corresponding common part data storage device 4 is updated.
If the edited part has been modified by synthesis, it means that the edited part has elements added by synthesis within it. Therefore, the internal elements are scanned, and it is determined whether to update the state transition data storage device 3 or common part data for each, and update the data.
Except for the variable part of the common data, the synthesizer 11 only adds state transition data. Therefore, when the synthesized data is subdivided, it can be determined that one of the storage devices originates.
If the variable part of the common data has been changed, the corresponding data in the corresponding common data application position storage device 5 is updated.

When the deletion of the common part is transmitted from the state transition display editing device 2 to the disassembly device 12, the disassembly device 12 deletes the corresponding data from the common portion data application position storage device 5.
When the common part combining position is added from the state transition display editing device 2 to the disassembly device 12, the disassembly device 12 adds new data to the common part data application position storage device 5. After the addition, the designation of the common part data to be applied and the contents of the variable part of the common part data are received from the state transition display editing device 2 to complete the data.
When an element such as a state or transition is added from the state transition display editing device 2 to the disassembling device 12, it is data belonging to the state transition data or to which common part data belongs Whether the data is data is acquired from the state transition display editing device 2, and the corresponding storage device is distinguished, and processing is performed.

Next, operation | movement of the decomposition | disassembly apparatus 12 is demonstrated using the flowchart of FIG.
After the element is edited on the state transition display editing device, it is determined whether or not the operation is an addition / deletion process of the common part data application position (step 31). Processing is performed (step 32), and the process ends. If no, it is determined whether or not the value of the variable element at the common part data application position is changed (step 33). If yes, the variable element is updated (step 34), and the process ends. . If no, it is determined whether the tag of the element is that of the state transition data storage device (step 35). If yes, the data of the state transition data storage device is updated (step 36). . If no, the corresponding data in the common unit data storage device is updated (step 37).

The state transition display editing device 2 presents the data of the state transition diagram synthesized by the synthesizing device 11 to the user and transmits the user's editing operation to the disassembling device 12.
Upon receiving an operation from the user, the state transition display editing device 2 adds / deletes / changes actions / labels such as states and transitions, adds a portion where the common portion data is combined, and deletes a position where the common portion data is combined. New creation of common part data, deletion of common part data, and setting change of variable part of common part data. Regarding addition / deletion / change of states, transitions, etc., from the data of the state transition diagram acquired from the synthesizing device 11, whether the corresponding part is from the data of the state transition data storage device 3, or from the data of the common part data storage device 4 Since it is possible to determine whether the edited element is transmitted, when the edited result is transmitted to the disassembling apparatus 12, the edited element can be distinguished and transmitted.

The state transition display editing apparatus 2 displays the state transition diagram to the user in the same manner as a general computer, such as display on a CRT or liquid crystal monitor, or printing by a printer. As an input means from the user, a mouse or a keyboard can be considered.
When displaying the synthesized state transition diagram, the display position must be determined for the state and transition. Regarding the data stored in the state transition data storage device 3, the display position data is Uses the position specified when creating a state or transition.
Alternatively, when the common part data is added, the state transition display editing device 2 may automatically move appropriately. When the state transition display editing device 2 automatically moves, there is a method of moving each state until the state is stabilized by giving repulsion between the states arranged within a certain distance. As for the transition, there is a method of increasing or decreasing the shape in proportion to the distance between the incoming and outgoing states.

  The state transition display editing device 2 can follow the manner of a general state transition diagram editor for the method of adding / deleting / changing an action or changing a label or the like of a state or transition. However, in the case of an additional process, it is necessary to distinguish whether it is data to be stored in the state transition data storage device 3 or data to be handled as common part data. Therefore, if the data is to be handled as common part data, the common part data on the state transition display editing device 2 is designated in advance as the affiliation target of the new data, and the state transition display editing device 2 newly creates the data. Need to be crafted to process the data to be processed as part of the common data.

The following describes how these devices operate and operate with examples.
For example, the state transition data storage device 3 storing data as shown in FIG. 7, the common part data storage device 4 storing data as shown in FIG. 8, and the common part data application position storing data as shown in FIG. Consider the case where there is a storage device 5.
At this time, the synthesizing device 11 first reads data whose data ID is 1 in the common part data application position storage device 5 of FIG. This data is a definition of a parallel state. Then, the data shown in FIG. 7 is read from the state transition data storage device 3, and this is held as the whole data. Since the application destinations of the common part data application position are S2 and S3, S2 and S3 are searched from the entire data, and the SA designated as the common data is combined with S2 and S3 in a parallel state. At this time, the SA has a variable element {g}. Since this value is specified as g = 4 on the data of the common part data application position, the guard condition [gv <{g}] of the transition on the SA including the variable element is [gv <4 on the entire data. ] Is synthesized.
The result of this synthesis is represented as a parallel state including S2 and S3 in FIG.

Next, data with ID 2 is read out and processed in the same way as with ID 1 and this is the parallel state of S3 and S5 in FIG. The same applies to data with an ID of 3.
Next, the data with ID 4 is synthesized. This has in common the definition of events and actions for one state. Since the application positions of this data are S2 and S4, a common event / action definition is synthesized for S2 and S4 on the entire data. This result is a description of the action corresponding to the event described in the squares indicating S2 and S4 in FIG.
FIG. 10 shows the result of processing all the common part data application positions shown in FIG.

  The readability is low as it is in FIG. Therefore, if the user is not particularly interested in the SA of the composite data, the compositing device is used so that the data with IDs 1 and 3 in the common part data application position storage device 5 is not composited using the common part display selection mechanism 6. 11 is instructed. Then, as shown in FIG. 11, unnecessary information is not displayed, and readability can be improved.

  With respect to the data in the common part data application position storage device 5 instructed not to be combined, the display can be simplified by marking the state that is the application position. In FIG. 12, a triangular flag is displayed at the common part data application position with ID = 1, and a square flag is displayed at the application position with ID = 3. When this display method is adopted, it can be expressed that the synthesis result that is not visible at each application position is hidden. It is possible for the state transition display editing device 2 to automatically assign what kind of mark is to be added, and it is specified by the user by saving the mark information to be added to the common part data application position storage device 5 Marks can also be displayed.

Next, a case where an editing operation is added to this data will be described.
Assume that the state transition display editing apparatus 2 displaying FIG. 12 newly creates a state S6 and creates transitions S3 to S6 and S6 to S2 as shown in FIG. In this case, a tag indicating that it is the data of the state transition data storage device 3 is automatically assigned as described above by creating the S6 and each transition without instructing that they are common part data. This additional data is added as new data in the state transition data storage device 3 by the disassembling device 12.
In the case of editing / deleting the states of S1 to S5 and transitions between them, the editing contents are determined to be related to the state transition data storage device 3 as in the case of addition, and the data of the state transition data storage device 3 is determined. Is updated.

  In the state transition display editing apparatus 2 displaying FIG. 13, a guard condition of [p <10] is created for the transition from the combined state S3 and S5 to the end from the combined state S3 and S5. In the case of FIG. 14, since this transition is a result created by composition, a tag indicating the common part data application position with ID 2 is assigned by the composition device 11. Therefore, the disassembling apparatus 12 determines that the change of the transition is a change related to the SB of the common part data storage device 4 and edits the data of the common part data storage device 4. When the common part data storage device 4 is updated, the other combined portions where the common part data is used are also updated at the same time.

When creating a new state and transition in the synthesized part as shown in FIG. 15, in order to inform the state transition display editing apparatus 2 in advance of the user's intention as to whether or not it is added as a common part, Perform a specific operation. The specific operation includes means such as selecting “add to this common part data” from the menu after instructing a place to be added such as b1 or b2. A tag related to the common part data application position is added to the element added after such an operation, and data is added to the common part data storage device 4 by the disassembling device 12 using the tag.
The addition and deletion of the common part data application position allows the user to select which common part data is added / deleted after the user selects the state that is the application position. In accordance with this editing operation, the disassembly device 12 updates the data in the common part data application position storage device 5.
When it is unclear whether the editing operation is related to the state transition data storage device 5 or the common part data storage device 4, the state transition display editing device 2 can make an inquiry to the user.

  In the first embodiment, the state is set as the synthesis application position. However, it is also possible to have the transition as the synthesis application position and have a common guard condition as common part data.

According to the first embodiment, state transitions that occur frequently are provided as common part data separately from the state transition data, and state transition diagram data, state transition data, common part data, and common part data are state transitioned. It is expressed by the data of the common part data application position indicating where to synthesize the data, and then the respective data are synthesized and presented to the user, and the editing result of the user is decomposed and stored in each of the above data The data of the common part can be unified, so that there is no need to write the same thing over and over, and there is an effect that it is not necessary to repeatedly apply the same correction to the figure when the common part is corrected.
Further, by making it possible to switch whether or not to synthesize the common part data, the state transition diagram can be appropriately omitted and the readability can be improved.
