Embodiment Construction

[0030] The core idea of ​​the present invention is to provide an extensible document model and a method for managing the document model, which can dynamically expand the document model with a notification mechanism, so that the extension components conforming to a certain interface can be arbitrarily installed and uninstalled, and the model can be modified Synchronization of all extensions of the model is then handled in a unified fashion.

[0031] The present invention provides an extensible document model, and the structural block diagram of an embodiment of the device is as follows figure 1 As shown, the present invention is an extensible document model packaged on the basis of the document model.

[0032] The extensible document model includes a basic document model, a model modification notification transfer device, a plurality of extension components, an extension component installation module, and an extension component uninstallation module.

[0033] The basic documen...

Abstract

An expandable file model consists of file model with notification mechanism, expansion component erection module for erecting expansion component in said file model according to expansion requirement, expansion component unloading module for unloading expansion component in said file model and model revision notification retransmission unit for monitoring and collecting varied event of each node on said file model as well as for retransmitting varied event to each relevant expansion component.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a device for establishing an extensible document model and a method for managing the document model used in the process of developing a document editor in an integrated development environment. Background technique [0002] In the development process of the document editor of the IDE (Integrated Development Environment), it is necessary to establish a document model for storing the document data structure. The document model generally only has simple document data access capabilities. In order to facilitate the processing of the model, it is necessary to cache some data extracted from the model, expand some model linkage operations or some additional related data, etc. [0003] For example: when editing a UML (Unified Modeling Language) class diagram, the current model is to refer to the UML specification to build the basic model, and only use the nodes of the tree to inde...
