Example 1 with LinkingHelper

use of org.eclipse.xtext.linking.impl.LinkingHelper in project xtext-core by eclipse.

the class LazyLinkingResourceTest method testEObjectReference.

@Test
public void testEObjectReference() throws Exception {
    final EAnnotation source = EcoreFactory.eINSTANCE.createEAnnotation();
    final EObject referencedObject = XtextFactory.eINSTANCE.createGrammar();
    LazyLinkingResource res = new LazyLinkingResource();
    res.setLinkingHelper(new LinkingHelper() {

        @Override
        public String getCrossRefNodeAsString(INode node, boolean convert) {
            return node.getText();
        }
    });
    res.setEncoder(new LazyURIEncoder() {

        @Override
        public boolean isCrossLinkFragment(Resource res, String s) {
            return "foo".equals(s);
        }

        @Override
        public Triple<EObject, EReference, INode> decode(Resource res, String uriFragment) {
            return Tuples.create((EObject) source, EcorePackage.Literals.EANNOTATION__REFERENCES, (INode) new LeafNode());
        }
    });
    res.setLinkingService(new ILinkingService() {

        @Override
        public List<EObject> getLinkedObjects(EObject context, EReference reference, INode node) throws IllegalNodeException {
            return Lists.newArrayList(referencedObject);
        }
