Example 1
private void testSequence(String stringModel) throws Exception {
	EObject model = getModel(stringModel);
	ISerializationContext context = nmSequencer.findContexts(model, true, null).iterator().next();
	DebugSequenceAcceptor actual = new NoEnterNodesDebugSequenceAcceptor(false);
	ISemanticSequencer semanticSequencer = semanticSequencerProvider.get();
	ISyntacticSequencer syntacticSequencer = syntacticSequencerProvider.get();
	IHiddenTokenSequencer hiddenTokenSequencer = hiddenTokenSequencerProvider.get();
	semanticSequencer
			.init((ISemanticSequenceAcceptor) syntacticSequencer, ISerializationDiagnostic.STDERR_ACCEPTOR);
	syntacticSequencer.init(context, model, (ISyntacticSequenceAcceptor) hiddenTokenSequencer,
			ISerializationDiagnostic.STDERR_ACCEPTOR);
	hiddenTokenSequencer.init(context, model, actual, ISerializationDiagnostic.STDERR_ACCEPTOR);
	semanticSequencer.createSequence(context, model);
	//		System.out.println(actual);
	//		System.out.println(NodeModelUtils.compactDump(NodeModelUtils.findActualNodeFor(model), true));
	assertEquals(Joiner.on("\n").join(getNodeSequence(model)), Joiner.on("\n").join(actual.getColumn(4)));
