Visual modeling platform based on GMF

Abstract

The invention provides a visual modeling platform based on a GMF (Graphical Modeling Framework). The visual modeling platform is characterized in that on the basis of a definition testing system meta model, a testing system model and a data instance editor are built by using a GMF technology based on a model driven development method. Through a definition domain model, a graphical model, a tooling model and a mapping model combining the definition domain model, the graphical model and the tooling model, an XML (Extensive Markup Language) file which is converted by a testing model and conforms to corresponding Schema is resolved, and visual modeling and automatic generation of partial codes are realized. The visual modeling platform has the advantages that the model driven thought is introduced into the testing field; the model is used as a core; the reutilization of testing resources is realized; and the testing period is effectively shortened.

Description

technical field [0001] The invention relates to a visual modeling platform. More specifically, it refers to a visual modeling platform based on GMF (Graphical Modeling Framework, Graphical Modeling Framework), which can define views in the way of defining models. Background technique [0002] Early graphical interface applications were mainly developed using the GEF (Graphical Editing Framework, Graphical Editing Framework) framework, such as: JBPM process definition tool, using the combined mode of GEF+javaBean, the disadvantage of this method is the processing of the model layer It is too cumbersome and requires developers to manually implement the model notification mechanism, and it is not conducive to later expansion and maintenance. Once the requirements change, it is very difficult to modify the model structure. [0003] EMF (Eclipse Modeling Framework) can help us develop Eclipse applications in a model-driven manner. Specifically, it defines a meta-model called Eco...

Problems solved by technology

[0005] So I tried the combination mode of EMF+GEF, because EMF (Eclipse Modeling Framework, Eclipse Modeling Framework) is relatively mature in model mapping processing, and the entity class driven by EMF also has a notification mechanism, which can change the model structure Notification of status changes to the control layer, but there are new difficulties in the process of use. EMF and GEF have their own command processing mechanisms to define the modification operations on the model. The interfaces defined by the two mechanisms are different. There is no universal approach
