Examples with XDocument org.eclipse.n4js.xtext.ide.server.XDocument used on opensource projects

Example 1 with XDocument

use of org.eclipse.n4js.xtext.ide.server.XDocument in project n4js by eclipse.

the class N4JSRenameService method rename.

// #################################################################################################################
// rename
// 
// In case of #rename() we entirely replace the implementation from the super class by our own implementation (in
// order to reuse reference finding as far as possible, for consistency):
@Override
public WorkspaceEdit rename(Options options) {
    RenameParams renameParams = options.getRenameParams();
    CancelIndicator cancelIndicator = options.getCancelIndicator();
    ResourceTaskContext rtc = resourceTaskManager.currentContext();
    if (rtc == null || !rtc.isTemporary()) {
        throw new IllegalStateException("N4JSRenameService#rename expects to be invoked within a temporary resource task context");
    }
    ResourceSet resourceSet = rtc.getResourceSet();
    XtextResource resource = rtc.getResource();
    XDocument document = rtc.getDocument();
    int offset = document.getOffSet(renameParams.getPosition());
    // in case the temporary resource task context we are using was created without 'resolveAndValidate' we need to
    // trigger resolution (not validation) here:
    EcoreUtil2.resolveLazyCrossReferences(resource, cancelIndicator);
    EObject element = getElementToBeRenamed(resource, offset);
    if (element == null) {
        // empty edit
        return new WorkspaceEdit();
    }
    WorkspaceEdit result = computeRenameEdits(resourceSet, element, renameParams.getNewName(), resourceTaskManager.createLiveScopeIndex(), cancelIndicator);
    return result;
}

}

Example 3 with XDocument

use of org.eclipse.n4js.xtext.ide.server.XDocument in project n4js by eclipse.
