Example 2 with EObjectAtOffsetHelper

use of org.eclipse.xtext.resource.EObjectAtOffsetHelper in project xtext-core by eclipse.

the class DiagnosticResolution method apply.

public WorkspaceEdit apply() {
    DiagnosticModificationContext modificationContext = factory.createModificationContext();
    try {
        XtextResource resource = options.getResource();
        URI uri = resource.getURI();

        EObjectAtOffsetHelper helper = new EObjectAtOffsetHelper();
        EObject obj = helper.resolveContainedElementAt(tmpResource, offset);
        IChangeSerializer serializer = modificationContext.getSerializer();
        serializer.addModification(obj, modification);
