Examples with ILinkingService org.eclipse.xtext.linking.ILinkingService used on opensource projects

Example 1 with ILinkingService

use of org.eclipse.xtext.linking.ILinkingService 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);
        }
    });
    res.setDiagnosticMessageProvider(new LinkingDiagnosticMessageProvider());
    assertEquals(referencedObject, res.getEObject("foo"));
}

Example 2 with ILinkingService

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

the class LazyLinkingResourceTest method testWarningInsteadOfError.

@Test
public void testWarningInsteadOfError() throws Exception {
    final EAnnotation source = EcoreFactory.eINSTANCE.createEAnnotation();
    LazyLinkingResource res = new LazyLinkingResource();
    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 Collections.emptyList();
        }
    });
    res.setDiagnosticMessageProvider(new LinkingDiagnosticMessageProvider() {

        @Override
        public DiagnosticMessage getUnresolvedProxyMessage(ILinkingDiagnosticContext context) {
            return new DiagnosticMessage("myMessage", Severity.WARNING, null);
        }
    });
    assertTrue(res.getWarnings().isEmpty());
    assertNull(res.getEObject("foo"));
    assertEquals(1, res.getWarnings().size());
    assertTrue(res.getErrors().isEmpty());
    assertEquals("myMessage", res.getWarnings().get(0).getMessage());
