Examples with IEObjectDescription org.eclipse.xtext.resource.IEObjectDescription used on opensource projects

Example 1 with IEObjectDescription

use of org.eclipse.xtext.resource.IEObjectDescription in project xtext-eclipse by eclipse.

the class JdtBasedSimpleTypeScope method createScopedElement.

public IEObjectDescription createScopedElement(String fullyQualifiedName) {
    InternalEObject proxy = createProxy(fullyQualifiedName);
    IEObjectDescription eObjectDescription = EObjectDescription.create(getQualifiedNameConverter().toQualifiedName(fullyQualifiedName), proxy);
    return eObjectDescription;

Example 2 with IEObjectDescription

use of org.eclipse.xtext.resource.IEObjectDescription in project xtext-eclipse by eclipse.

the class JdtIndexedJvmTypeAccess method findAccessibleType.

@Override
protected EObject findAccessibleType(String fragment, ResourceSet resourceSet, Iterator<IEObjectDescription> fromIndex) throws UnknownNestedTypeException {
    // we know that the iterator is not empty thus we can directly obtain the handles et al without additional guards

    allVisibleContainerHandles.addAll(plainProjectsState.getVisibleContainerHandles(javaProject.getElementName()));
    List<String> visibleContainerHandles = allVisibleContainerHandles;
    IEObjectDescription bestDescription = null;
    while (fromIndex.hasNext() && !visibleContainerHandles.isEmpty()) {

        IEObjectDescription description = fromIndex.next();
        URI trimFragment = description.getEObjectURI().trimFragment();
        String handle = javaProjectsState.getContainerHandle(trimFragment);
        int idx = visibleContainerHandles.indexOf(handle);
        if (idx >= 0) {
            bestDescription = description;
            // reduce the search scope - only check containers that are better than the current
            visibleContainerHandles = allVisibleContainerHandles.subList(0, idx);
        }
    }
    if (bestDescription != null) {
        return getAccessibleType(bestDescription, fragment, resourceSet);
    }
    return null;
