Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
In the description of the present application, it is noted that the terms "first", "second", and the like are used merely for distinguishing between descriptions and are not intended to indicate or imply relative importance.
Additional features and advantages of the application will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the embodiments of the application. The objectives and other advantages of the application may be realized and attained by the structure particularly pointed out in the written description and drawings.
An embodiment of the present application provides a method for establishing a model attribute, please refer to fig. 1, where fig. 1 is a flowchart of the method for establishing a model attribute provided in the embodiment of the present application, and the method includes the following steps:
step S1: and acquiring the original element instance and the classification attribute field corresponding to the original element instance from the specified database.
It will be appreciated that the designated database is the database that stores the original component instances in which the original component instance classifications are stored. The original component instance is a reusable component stored in a database and the category attribute field is used to identify the category. For example, the classification attribute field for identifying a classification includes a classification name, a classification description, a classification parent name, and the like. For example, the auto cad drawing is used for drawing, the component instance is various original component instances including an original component instance such as a rectangular component instance in the component database, and the classification name, the classification description and the classification parent name of the rectangular component instance are all classification attribute fields of the rectangular component instance. In the design file created by opening in the design platform software (such as MicroStation), each component dragged into the design file is an original element instance.
Step S2: a global classification attribute declaration is generated based on the original element instance and the classification attribute fields.
It will be appreciated that the global classification attribute declares relevant information for establishing classification attributes of the original component instance, such as an index of the classification attribute field of the original component instance, i.e., a spatial relationship that records the classification attribute field of the original component instance, the classification attribute field storing the original component instance, and the spatial relationship of the original component instance.
As an embodiment, the global classification attribute declaration may be a classification schema, which may be understood as a table, an index, a view, a stored procedure, or the like, and the classification schema is a collection of tables, indexes, views, and stored procedures related to classification. Each original component instance can create a classification schema, and the classification schemas corresponding to all the original component instances form a set, namely a classification schema set, namely a classification attribute declaration set.
Step S3: an attribute instance is generated based on the classification attribute field and the global classification attribute declaration.
Referring to fig. 2, fig. 2 is a flowchart of an attribute example generation step provided by an embodiment of the present application. Optionally, step S3 includes the following substeps:
step S31: the component model of the original component instance is set based on the specified spatial parameters.
In the design platform software (such as MicroStation software), the component model is placed at a specified position or in a specified direction (rotation angle) in a design file created by a developer, so that the development and design of the model are facilitated.
Step S32: and generating an attribute instance based on the classification attribute field and the global classification attribute declaration, and loading the attribute instance to the element model.
It can be understood that the attribute instance of the original element instance is generated according to the classification attribute field corresponding to the original element instance and the global classification attribute declaration corresponding to the original element instance, and the attribute instance of the original element instance is the corresponding classified instance of the original element instance. The global classification attribute declaration may be a classification schema, and when a collection of a table, an index, a view, and a storage procedure of a classification in the classification schema is changed, an attribute instance of an original component instance corresponding to the classification schema is changed, so that a classification attribute field corresponding to the original component instance is changed correspondingly. The classification schema can be regarded as a global variable of an original component example, a table, an index and the like of classification attributes in the classification schema change, and the classification attributes in the component model change correspondingly, so that the classification attributes in the component model can be prevented from being changed one by one, and the efficiency of changing the classification attributes of the component model can be improved.
In the conventional method, when a developer adjusts the classification attribute of a component model created in the design platform software, the classification attribute of another component model needs to be manually modified based on the adjusted classification attribute. Optionally, the present embodiment can implement the update of the same classification attribute on the global all-element model based on the update of the global classification attribute declaration and the set of classification attribute declarations.
Referring to fig. 3, fig. 3 is a flowchart of a step of updating a global classification attribute declaration according to an embodiment of the present application. Optionally, after step S2, the method for establishing model attributes further includes step S6, and step S6 includes the following sub-steps:
step S61: and when the classification attribute declaration set has a classification attribute declaration which is different from the global classification attribute declaration and corresponds to the original element instance, replacing the classification attribute declaration which corresponds to the original element instance in the classification attribute declaration set with the global classification attribute declaration, wherein the classification attribute declaration set comprises the classification attribute declarations of all the model element instances.
It can be understood that the classification attribute declaration set is a classification attribute declaration existing in the component model, the classification attribute declaration set includes different classification attribute declarations, when a classification attribute declaration corresponding to the original component instance and different classification attribute declarations corresponding to the global classification attribute declaration exist in the classification attribute declaration set, the classification attribute declaration corresponding to the original component instance is changed, so that the classification attribute declaration corresponding to the original component instance in the classification attribute declaration set needs to be replaced by the global classification attribute declaration, and the global classification attribute declaration is a classification attribute declaration corresponding to the original component instance at present.
Step S62: and when the classification attribute declaration corresponding to the original element instance does not exist in the classification attribute declaration set, adding a global classification attribute declaration in the classification attribute declaration set.
It can be appreciated that when a classification attribute declaration corresponding to the original element instance does not exist in the set of classification attribute declarations, the classification attribute declaration corresponding to the original element instance is added in the set of classification attribute declarations as a global classification attribute declaration to update the set of classification attribute declarations.
Continuing with fig. 1, step S4: the property instance is added to the original element instance to generate a model element instance.
Referring to fig. 4, fig. 4 is a flowchart illustrating exemplary steps for updating model elements according to an embodiment of the present application. Step S5 is divided into the following substeps:
step S51: an updated set of classification attribute declarations is obtained based on the updated classification attribute field of the original element instance in the specified database.
It is to be understood that the updating of the original component instance includes adding a field of the original component instance, modifying a field name or deleting a field or removing a class in the specified database, and when the class attribute field of the original component instance in the specified database is updated, the index, linked list, etc. of the class attribute in the class attribute declaration set is correspondingly updated to adapt to the change of the class attribute field of the original component instance.
Step S52: and updating the global classification attribute statement in the model element instance based on the updated classification attribute statement set to obtain an updated classification attribute statement.
It can be understood that the classification attribute of the original element instance in the designated database changes, the index and the linked list of the classification attribute in the classification attribute declaration set are updated, and the classification attribute declaration corresponding to the attribute instance in the model element instance is added for adaptive updating to obtain the updated classification attribute declaration.
As an implementation manner, when the classification attribute field of the original component instance in the designated database is updated, the classification attribute in the classification schema corresponding to the original component instance is updated correspondingly to obtain an updated classification schema, the classification attribute declaration set also completes the update of the classification attribute correspondingly, and the obtaining of the updated classification attribute declaration needs to be based on the updated classification schema, so that step S51 may be omitted in this implementation manner, and step S52 updates the global classification attribute declaration in the model component instance based on the updated classification schema to obtain the updated classification attribute declaration.
Step S53: an update attribute instance is generated based on the classification attribute field and the update classification attribute declaration.
It can be understood that the attribute instance is generated based on the classification attribute field and the global classification attribute declaration, and when the global classification attribute declaration corresponding to the original component instance is updated, the attribute instance generated based on the global classification attribute declaration corresponding to the original component instance and the classification attribute field is correspondingly updated to obtain an updated attribute instance.
Step S54: and replacing the attribute instance in the original element instance with the updated attribute instance to update the model element instance.
It can be understood that the attribute instance addition generates a model element instance on the original element instance, and when the attribute instance is updated to an updated attribute instance, the model element instance is updated correspondingly to obtain an updated model element instance.
Referring to fig. 5, fig. 5 is a flowchart illustrating a step of warehousing original device instances according to an embodiment of the present application. Step S0 includes the following substeps:
step S01: an original element instance is created.
Referring to fig. 6, fig. 6 is a flowchart of a step of creating an original component instance according to an embodiment of the present application. Optionally, step S01 is divided into the following substeps:
step S011: defining original element basic information, wherein the basic information comprises original element names, original element descriptions, original element classifications and original element specialties.
It will be appreciated that the raw elements in the specified database are built from information provided by the user, the element names are used to identify different instances of the elements, the raw element descriptions are used to explain the role and function of the elements, the raw element classifications are used to classify the raw elements, the raw element specializes such as warm-up drainage data when modeling the engineering project, etc.
Step S012: and defining model information of the original element, wherein the model information comprises a model name and a model file name.
It is understood that, when the drawing design is performed, the model information includes a 3D model file name, a 3D model, a 2D model file name, and a 2D model file.
Step S013: an original element field is defined, which is inherited from the classification property field of the parent of the original element.
It will be appreciated that the fields of the original element are inherited from the classification property field of the parent of the original element, and the default values for the fields of the original element may be different from the classification property field of the parent of the original element.
Continuing with fig. 5, step S02: the raw component instances are binned into a designated database based on the classification.
It will be appreciated that defining a classification is actually building a classification dictionary based on which the original component instances are classified. Defining the classification comprises defining a classification statement of the original element instance and establishing a classification attribute field corresponding to the original element instance based on the classification statement of the original element.
Referring to fig. 7, fig. 7 is a flowchart illustrating a step of binning original component instances into a specified database based on classification according to an embodiment of the present application. Optionally, step S02 is divided into the following substeps:
step S021: defining basic information of classification, wherein the basic information of classification comprises a classification name, a classification description and a classification parent-level name.
Step S022: defining a classification inheritance field, wherein the inheritance field is an attribute field of a classification parent level.
Step S023: and defining a classified self-contained field, wherein the classified self-contained field is a classified specific field, and the classified self-contained field cannot be the same as the classified parent-level name.
Step S024: the raw component instances are binned into a designated database based on the classification.
It is understood that step S021, step S022, step S023 and step S024 are actually building a classification dictionary, which is built based on information provided by the user and defines basic classification information, wherein the basic classification information includes a classification name, a classification description and a classification parent name, and defines identification, functions and inheritance relationships of the classification. The define class inherit field is the attribute field that defines the parent of the class. The self-contained field of the defined classification can be used as a distinguishing point of different classifications from the same parent level, and the self-contained field of the defined classification cannot be renamed with the field of the parent level. The raw component instances are stored in a specified database based on the classification in step S024.
