Examples of org.antlr.runtime.ANTLRStringStream

org.antlr.runtime.ANTLRStringStream
A pretty quick CharStream that pulls all data from an array directly. Every method call counts in the lexer. Java's strings aren't very good so I'm avoiding.

        NodeTestDSLParser parser = new NodeTestDSLParser( new CommonTokenStream( lexer ) );
        return parser;
    }


    private static NodeTestDSLParser getParser(final String source) throws IOException {
        NodeTestDSLLexer lexer = new NodeTestDSLLexer( new ANTLRStringStream( source ) );
        NodeTestDSLParser parser = new NodeTestDSLParser( new CommonTokenStream( lexer ) );
        return parser;
    }

        return parse( name,
                      text.toString() );
    }


    private CharStream newCharStream(final String text) {
        return new ANTLRStringStream( text );
