Examples with ASN1Listener org.eclipse.titan.designer.parsers.asn1parser.ASN1Listener used on opensource projects

Example 1 with ASN1Listener

use of org.eclipse.titan.designer.parsers.asn1parser.ASN1Listener in project titan.EclipsePlug-ins by eclipse.

the class ASN1ReferenceParser method parseReference.

private Reference parseReference(final IFile file, final String input, final int line, final int offset) {
    Reference reference = null;
    StringReader reader = new StringReader(input);
    CharStream charStream = new UnbufferedCharStream(reader);
    Asn1Lexer lexer = new Asn1Lexer(charStream);
    lexer.setTokenFactory(new TokenWithIndexAndSubTokensFactory(true));
    ASN1Listener lexerListener = new ASN1Listener();
    // remove ConsoleErrorListener
    lexer.removeErrorListeners();
    lexer.addErrorListener(lexerListener);
    ModuleLevelTokenStreamTracker tracker = new ModuleLevelTokenStreamTracker(lexer);
    tracker.discard(Asn1Lexer.WS);
    tracker.discard(Asn1Lexer.MULTILINECOMMENT);
    tracker.discard(Asn1Lexer.SINGLELINECOMMENT);
    Asn1Parser parser = new Asn1Parser(tracker);
    parser.setProject(file.getProject());
    parser.setActualFile(file);
    parser.setLine(line);
    parser.setOffset(offset);
    parser.setBuildParseTree(false);
    ASN1Listener parserListener = new ASN1Listener();
    // remove ConsoleErrorListener
    parser.removeErrorListeners();
    parser.addErrorListener(parserListener);
    reference = parser.pr_parseReference().reference;
    return reference;
}

Example 2 with ASN1Listener

use of org.eclipse.titan.designer.parsers.asn1parser.ASN1Listener in project titan.EclipsePlug-ins by eclipse.

the class SpecialASN1Module method parseSpecialInternalAssignment.

/**
 * Parses the special internal assignments to build their semantic
 * representation.
 *
 * @param inputCode
 *                the code to parse.
 * @param identifier
