Examples with TypeVisibility org.eclipse.n4js.scoping.accessModifiers.AbstractTypeVisibilityChecker.TypeVisibility used on opensource projects

Example 1 with TypeVisibility

use of org.eclipse.n4js.scoping.accessModifiers.AbstractTypeVisibilityChecker.TypeVisibility in project n4js by eclipse.

the class VisibilityAwareTypeScope method isAccepted.

@Override
protected boolean isAccepted(IEObjectDescription description) {
    EObject proxyOrInstance = description.getEObjectOrProxy();
    if (proxyOrInstance instanceof Type) {
        Type type = (Type) proxyOrInstance;
        if (type.eIsProxy() && contextResource != null) {
            // we found a proxy. Only valid precondition for a proxy that was returned from a
            // UserDataAwareScope is that the resource that contains the real instance is already
            // available in the resource set and loaded.
            // thus it's save to use resourceSet.getEObject(uri, false) and it has to return a proper instance
            // 
            ResourceSet resourceSet = contextResource.getResourceSet();
            // don't load on demand

            } else {
                // assume the unresolved proxy to be visible to reduce number of follow-up problems.
                return true;
            }
        }
        // paranoid double check - object from resource set should never be a proxy
        if (!type.eIsProxy()) {
            TypeVisibility typeVisibility = checker.isVisible(contextResource, type);
