如何在Java中以编程方式合并EMF模型？

Question

有没有办法在Java中以编程方式将多个Ecore模型(2个或更多个)组合在一个Ecore模型中？所有模型都符合相同的元模型.

在:

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

日期:

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

Answer 1

Eclipse项目用于处理EMF比较和合并,称为EMF比较.

以下是他们提供的示例:

// 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的东西.您也可以手动完成更改.
