Example 6 with ISyntacticSequencer

use of org.eclipse.xtext.serializer.sequencer.ISyntacticSequencer in project xtext-core by eclipse.

the class FormatterTest method serializeToTokenBuffer.

protected void serializeToTokenBuffer(String model, ITokenStream out) throws Exception {
    EObject semanticObject = get(ParseHelper.class).parse(model);
    ISerializationDiagnostic.Acceptor errors = ISerializationDiagnostic.EXCEPTION_THROWING_ACCEPTOR;

    ISerializationContext context = new SerializationContext.RuleContext(null, (ParserRule) get(IGrammarAccess.class).getGrammar().getRules().get(0));
    syntactic.init(context, semanticObject, (ISyntacticSequenceAcceptor) hidden, errors);
    hidden.init(context, semanticObject, tokenstream, errors);
    tokenstream.init(context);
    semantic.createSequence(context, semanticObject);
}

Example 7 with ISyntacticSequencer

use of org.eclipse.xtext.serializer.sequencer.ISyntacticSequencer in project xtext-core by eclipse.

the class SyntacticSequencerTest method testSequence.
