EMF模型比较与EMF比较

Question

我有两个基于同一ecore模型的EMF实例版本。我需要以以下格式准备一个从v1到v2更改的事物列表

public Comparison compare()
{
    // Load the two input models
    ResourceSet resourceSet1 = new ResourceSetImpl();
    ResourceSet resourceSet2 = new ResourceSetImpl();
    String xmi1 = "src/test/java/com/equifax/ic/provisioning/service/v1.xmi";
    String xmi2 = "src/test/java/com/equifax/ic/provisioning/service/v2.xmi";
    load(xmi1, resourceSet1);
    load(xmi2, resourceSet2);

    // Configure EMF Compare
    EMFCompare comparator = EMFCompare.builder().build();

    // Compare the two models
    IComparisonScope scope = EMFCompare.createDefaultScope(resourceSet1, resourceSet2);
    return comparator.compare(scope);
}

@Test
public void testCompare()
{
    Comparison comparison = compare();
    List<Diff> differences = comparison.getDifferences();

    for(Diff d: differences)
    {
        System.err.println("d.getKind(): "+d.getKind());
        System.err.println("d.getMatch(): " + d.getMatch());
        System.err.println("State: " + d.getState());
    }

    assertSame(Integer.valueOf(12), Integer.valueOf(differences.size()));
}

d.getKind(): ADD
d.getMatch(): MatchSpec{left=BillableSystemEvent@1b5340c Application Processed, right=BillableSystemEvent@16c163f Application Processed, origin=<null>, #differences=2, #submatches=2}
State: UNRESOLVED

d.getKind(): DELETE
d.getMatch(): MatchSpec{left=BillableSystemEvent@1b5340c Application Processed, right=BillableSystemEvent@16c163f Application Processed, origin=<null>, #differences=2, #submatches=2}
State: UNRESOLVED

我不能说我真的理解您想要实现的一切，但据我所知，您对EMF Compare格式的差异并不真正感兴趣。相反，您正在尝试为差异生成一种不同的表示形式。

您可能对重新实现IDiffProcessor感兴趣。每次我们检测到变化时，都会通知Diff处理器。默认情况下，我们创建“diff”实例...没有什么可以阻止您生成DML语句。您可以在这里快速了解IDiffProcessor API。
