Abstract

PROBLEM TO BE SOLVED: To enable a user to customize an object by inhibiting or permitting the deletion and protecting a password not for an application level but for the object itself. SOLUTION: This information processor consists of a CPU 1, a display device 2, a hard disk device 3, a main storage 4, a mouse input device 5 and a keyboard input device 6. The method executable and unexecutable states are alternately changed by the instruction of a user. In an instance execution mode, a selected method is executed to a selected object if the selected method is kept in a password non-protection state. If the method that selected in an instance execution mode is kept in a password protection state, the user is instructed to input a password. Then the selected method is executed to a selected instance as long as the password inputted by the user is correct.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus to which the object-oriented theory is applied.

[0002]

2. Description of the Related Art An information processing apparatus is realized by operation of software installed in a computer. In recent years, software has been provided with an object for realizing a user-friendly man-machine interface. Elements of a graphic user interface (windows, windows, etc.) displayed on a display device and operated by an input means such as a mouse by applying the orientation theory.
In many cases, resources such as menus, buttons, edit controls, and scroll bars, or data associated with resources (such as icons) are encapsulated using a class structure. That is, data handled by software based on the object-oriented theory is not a simple type such as an integer type, but an instance of an object typed as a specific class (incarnation,
(Specified entity). This class is
It is similar to a structure, and generally includes a group of variables called data members and a group of methods that perform some behavior.

[0003] The group of methods can include an event handler which is called when a specific event occurs, changes the value of a certain data member, or performs an action such as calling another specific method. . For example, an event handler that displays a list of executable methods for the object when the right mouse button is clicked can be described.

[0004] Then, an instance of an object having this event handler is generated, and a resource related to the instance is displayed on a display device. When the user has the focus and is in an enabled state, the user can right-click this resource. When clicked, the event handler is called, and the above list is displayed. And
When the user selects a method to be executed from the list, the method (the event handler associated with the selected resource) is executed for the instance. For example, if you click the "Document" instance with the right mouse button, its methods "Open",
A menu such as "Delete" is displayed next to the instance. If the "open" method is selected, a module for editing is activated, the data of the document is displayed in the module, and the document is edited.

[0005]

However, in the prior art, the event handler is always called when a specific event occurs, so that the user changes the method of the object from the executable state to the impossible state. Or it could not be changed from an unexecutable state to an enabled state. Therefore, for example, it has not been possible to satisfy a user's request to make a method “delete” currently executable for a certain object unexecutable for the purpose of prohibiting erroneous deletion. Further, in the related art, a user cannot protect a method of an object with a password. Therefore, for example, the method of "open" which can be currently executed for an object can be satisfied by a user who wants to provide a password protection function for the purpose of not disclosing the contents of the object to a third party. Did not.

Accordingly, an object of the present invention is to provide an information processing apparatus capable of customizing the behavior of an object.

[0007]

An information processing apparatus according to the present invention includes means for recording a list of a plurality of objects that can be generated on a non-volatile storage medium and a list of method candidates that can be executed for each object. Means for recording in a non-volatile storage medium in association with each object, information indicating whether each method is currently executable, information indicating whether or not the password protection state and the password character string, Means for recording in a non-volatile storage medium corresponding to each method, means for switching between an object editing mode, an instance generation mode, and an instance execution mode according to a user's instruction, and an object to be edited by a user in the object editing mode. Means to select the object, and in the object edit mode, A means for displaying a list of currently executable or non-executable methods, and a means for mutually changing a state between an executable state and an unexecutable state according to a user's instruction in the object editing mode, Means for mutually changing the state of a method executable by a user's instruction in a password protected state and a password unprotected state in an object editing mode, and a means for displaying a list of objects that can be generated in an object instance generating mode. Means for allowing the user to select an object to be generated in the instance generation mode, means for generating an instance of the type of the selected object in the instance generation mode, and an instance to be executed by the user in the instance execution mode. Means for selecting, in the instance execution mode, means for displaying a currently executable method for the selected instance, and, in the instance execution mode, a method to be executed among the displayed executable methods to the user. In the instance execution mode,
If the selected method is password protected, the means to execute the selected method on the selected object, and if the selected method is password protected in instance execution mode, Means for inputting a password and executing the selected method on the selected instance only when a valid password is input.

Means for switching between an object editing mode, an instance generation mode, and an instance execution mode in accordance with a user's instruction; means for allowing a user to select an object to be edited in the object editing mode; List of currently executable or non-executable methods Means for mutually changing a state between a state in which the method can be executed and a state in which the method cannot be executed in response to a user's instruction in the object editing mode; Means for mutually changing the method between a password protected state and a password unprotected state; and
Means for displaying a list of objects that can be created, means for allowing the user to select an object to be created in the instance creation mode, means for creating an instance of the type of the selected object in the instance creation mode, and instance execution mode A means for allowing a user to select an instance to be executed; and a means for displaying a currently executable method for the selected instance in an instance execution mode;
In the instance execution mode, means for allowing the user to select a method to be executed among the displayed executable methods, and, in the instance execution mode, when the selected method is in a password unprotected state, the selected object is executed. In the instance execution mode, if the selected method is in a password protected state, the user is required to enter a password, and only when a valid password is entered, Means for executing the selected method on the selected instance. With this configuration, deletion prohibition / permission and password protection can be performed not on the application level but on the object itself.

Next, an embodiment of the present invention will be described with reference to the drawings. Here, FIG. 1 is a configuration diagram of an information processing apparatus according to an embodiment of the present invention, and FIG. 2 is a configuration diagram of an “object table” according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a central processing unit that controls each device and makes logical decisions; 2 denotes a display device such as a liquid crystal display or a CRT (cathode ray tube); A hard disk device as a non-volatile storage medium for storing the program file and a data file such as an “object table” to be executed from the hard disk device 3;
Are a mouse input device and a keyboard input device for the user to send instructions to the system.

An "object table" file as shown in FIG. 2 is recorded on the hard disk device 3. That is, the “object table” records the names of objects that can be generated by the device and a plurality of executable methods corresponding to the objects. The method stores an “execution attribute” and a “password character string” indicating whether or not the method is currently executable and whether password protection is provided. Alternatively, a data member holding “execution attribute” and “password character string” and a method for changing the values of these data members may be described.

Specifically, when the method is currently executable and the password is not protected, the numerical value 01 is set as the “execution attribute”. When the method is currently executable and the password is protected, the numerical value 01 is set as the “execution attribute”. Numerical value 11 is recorded as the numerical value 11 as the “execution attribute” when the method cannot be executed at present. Nothing is initially recorded in the “password character string” (NUL
L), when the user sets any password, a specific character string is recorded. In the initial state, the numerical value 00 is set in the “execution attribute” of all the methods, and no characters are set in the “password character string”.

First, how to enter the object edit mode, instance creation mode, and instance execution mode will be described with reference to FIG. Here, FIG. 3 is a diagram showing a display example when a mode is selected in the embodiment of the present invention. When the user gives an instruction to enter the object editing mode by operating the mouse input device 5 or the keyboard input device 6 to select a menu on the display device 2 as shown in FIG. Into the instance creation mode,
The device enters the instance creation mode, and when instructed to enter the instance execution mode, the device enters the instance execution mode.

Next, the operation in the object editing mode will be described with reference to FIG. Here, FIG. 4 is a flowchart of the object editing process according to the embodiment of the present invention. As described above, the object editing mode is entered according to the user's instruction. At this time, in step 1, the central processing unit 1 reads out the “object table” file on the hard disk device 3 onto the main storage device 4.
In step 2, the central processing unit 1 refers to the read "object table" and displays an object list on the display device 2 as shown in FIG. That is, the object name and the currently executable method (that is, the “execution attribute” is 01 or 11) and the currently unexecutable method (that is, the “execution attribute” is 00) are associated with the object. indicate. At this time, only the method that can be currently executed is displayed at the top with a “O” mark indicating that. Further, only the method having the password protection (that is, the “execution attribute” is 11) is displayed at the top with a “P” mark indicating that fact.

Further, in this state, when the user double-clicks the desired method with the mouse input device 5,
As shown in FIG. 6, an editing panel is displayed, in which the user edits the method. That is, when the currently executable method is made unexecutable, the “executable” button is clicked with the mouse input device 5. Also, "executable" when making a method that is not executable at present executable
Click the button with the mouse input device 5 and click the "Password" button to add a password and enter the password to be set in the "Password box", or "No password" if no password is to be added. Click the button. Here, if the user clicks the “OK” button, the central processing unit 1 stores the “object table” data in the main storage device 4 as a file in the hard disk device 3 in step 4.

Next, the operation in the instance generation mode will be described with reference to FIG. Here, FIG. 7 is a flowchart of the instance generation processing in one embodiment of the present invention. As described above, an instance generation mode is entered according to a user's instruction.
The central processing unit 1 reads the “object table” file on the hard disk device 3 onto the main storage device 4.
In step 2, the central processing unit 1 refers to the read "object table" and displays an object list on the display device 2 as shown in FIG. In step 3, if the user clicks on the object generated by the user with the mouse input device 5 and clicks the "OK" button, in step 4, the central processing unit 1 displays an instance as shown in FIG.

Next, the operation in the instance execution mode will be described with reference to FIG. As described above, the process enters the instance execution mode in accordance with the user's instruction. At this time, in step 1, the central processing unit 1 reads out the “object table” file on the hard disk device 3 onto the main storage device 4. In step 2, the user clicks and selects an instance on the display device 2 with the mouse input device 5. In step 3, the central processing unit 1 displays a currently executable method corresponding to the selected instance on the "object table" next to the instance as shown in FIG.

In step 4, the user clicks a method on the display device 2 with the mouse input device 5 to select it. If the method selected in step 5 is password protected, proceed to step 7; otherwise proceed to step 6. In step 6, the central processing unit 1
Executes a method on the instance, and displays the result on the display device 2 as shown in FIG. 12, for example. In step 7, the central processing unit 1 prompts the user to input a password as shown in FIG. If it is determined in step 8 that the input password is valid, the process proceeds to step 6; otherwise, the process proceeds to step 9. In step 9, the central processing unit 1 displays on the display device 2 that the password input to the user is incorrect.

[0018]

According to the present invention, since a method for an object can be executed or disabled according to the user's request, erroneous operations such as erroneous deletion of an object that should not be deleted can be prevented. . In addition, since the password protection function can be used, only a limited number of users can be allowed to execute the method. From these things, the user can customize the object.
