Eclipse Modeling Framework @ JDJthe process of using emf is compatible with the mda approach of omg, however it is missing some of the essential properties of an mda tool.
emf is not a general-purpose code-generation tool. it generates eclipse plugins. it would be difficult to make emf generate, lets say, a .net application.
emf generates code from models. strictly speaking, an mda tool should generate platform-specific models (psm) before generating code. even though it may not line up with omg 100%, emf is one of the most powerful ambassadors for the mda approach.
process of using emf 【推荐阅读:Java Package Process】
the eclipse modeling framework (emf) is an open source code generation tool distributed under the eclipse umbrella. it is a tool created in the spirit of the omgs model driven architecture (mda) and an excellent example of the power of mda.
emf is capable of creating sophisticated editors from abstract business models. these editors are implemented as plugins for eclipse. emf creates feature complete implementations including persistence, business model implementation, editing framework and editors.
(note: websphere studio supports eclipse plugins. the eclipse ide may also be used to directly develop in websphere.)
in this article, well look at the anatomy of emf and what it produces by building a simple eclipse editor for keeping track of music collections.
emf and mda
in figure 1 we have outlined the typical process used when developing plugins with emf.
first, we need to create a business model (omgs pim). in emf, this... 下一页
