[antlr-interest] Modifying Java Source

[Ismet Ozalp]

First of all thank you all for your fast comments on the subject.

Terence, after I created the tokenRewriteStream

JavaLexer javaLexer = new JavaLexer(new ANTLRFileStream(file));
TokenRewriteStream tokenRewriteStream = new TokenRewriteStream(javaLexer);

Are you suggesting me to find tokens between {} and replace them with the
tokens I want?
In that case how can I detect class definition and inner class definitions
because i don't want to replace them. Maybe I am not completely
understanding
your suggestion. I feel like telling the grammar skip method definitions but
yet i am not successful.  I am using antlr 3.1.3. Also TokenRewriteStream's
delete(int from, int to) seems not deleting the tokens in it's token list? I
am just calling tokenRewriteStream.delete(10,20) and the tokens are still
there? Thank you very much...

Regards,
Ismet
