Code inside @members called two times.

[Mohan Radhakrishnan]

What could be the reason for calling this code multiple times ? This is called two times.

@members {

static{
    System.out.println(" Create Graph DB");
}

}

My code is this.

ANTLRInputStream ais = new ANTLRInputStream( new FileInputStream("file.java"));
JavaLexer jl = new JavaLexer(ais);
CommonTokenStream stream = new CommonTokenStream(jl);
JavaParser jp = new JavaParser( stream);
ParseTree pt = jp.compilationUnit();


ConfiguredRuleRegenerator rewriters = new ConfiguredRuleRegenerator( stream );
jp.addParseListener( rewriters );

ParseTreeWalker walker = new ParseTreeWalker();

/* walkers */
walker.walk(rewriters, pt);

Thanks,
Mohan

It is called once for the lexer and one once for the parser.

You can narrow the generation by specifying lexer::members or parser::members

 Thanks. I was facing a DB lock issue when i tried to put the ParseTree nodes in neo4j.
