如何在Java中以编程方式合并EMF模型? [英] How to merge EMF models programmatically in Java?

问题描述

是否有一种方法可以用Java以编程方式在单个Ecore模型中组合多个Ecore模型(2个或更多)?所有模型都遵循相同的元模型.

Is there a way to combine multiple Ecore models (2 or more) in a single Ecore model programmatically in Java? With all models conform to the same metamodel.

在:

Model1 conforming to metamodelX
Model2 conforming to metamodelX
model3 conforming to metamodelX
model4 conforming to metamodelX
model5 conforming to metamodelX

出局:

modelOut conforming to metamodelX and merge of Model1, Model2, model3, model4, model5 ...

推荐答案

有一个用于处理EMF比较和合并的Eclipse项目，称为EMF Compare.

There is Eclipse project for handling EMF comparing and Merging, called EMF Compare.

以下是他们提供的示例:

Here is example provided by them:

// Loading models
EObject model1 = ModelUtils.load(model1, resourceSet);
EObject model2 = ModelUtils.load(model2, resourceSet);

// Matching model elements
MatchModel match = MatchService.doMatch(model1, model2, Collections.<String, Object> emptyMap());
// Computing differences
DiffModel diff = DiffService.doDiff(match, false);
// Merges all differences from model1 to model2
List<DiffElement> differences = new ArrayList<DiffElement>(diff.getOwnedElements());
MergeService.merge(differences, true);

这确实提供了很好的方法来处理模型合并和其他比较工作.您也可以手动进行更改.

This really provides very good ways to handle model merging and other compare stuffs. You can also manually go through the changes.
