Example 51 with IEObjectDescription

use of org.eclipse.xtext.resource.IEObjectDescription in project n4js by eclipse.

the class FilterWithErrorMarkerScope method getSingleElement.

/**
 * Returns the first not filtered element found in the parent scope; if no such element is found, an
 * {@link IEObjectDescriptionWithError} is created for the element originally found in the parent scope by that
 * name.
 * <p>
 * Note that the extended behavior of looking for possibly shadowed elements makes only sense if the parent's
 * {@link IScope#getElements(QualifiedName)} returns more than one element and if
 * {@link IScope#getSingleElement(EObject)} is only an optimization in case only one element is present.
