[antlr-interest] ANTLR 3: Problem with static DFA class generation

[Oliver Zeigermann]

The attached patch for Java.stg (org/antlr/codegen/templates/) will
make the below lexer fragment work:

lexer grammar XMLLexer;
{
   boolean tagMode = false;
}

TAG_START_OPEN : { !tagMode }? '<' { tagMode = true; } ;
TAG_END_OPEN : { !tagMode }? "</" { tagMode = true; } ;

....

It simple makes all DFA code non static to allow full access to the
outer class' (Lexer) fields. The part that creates a single DFA per
decision and lexer like this:

class XMLLexer extends Lexer {

...

private dfa10 = new DFA10();

...

alt10 = dfa10.predict(input);

...

}

is missing, as it requires changes not only to the template. 

Anyway, hopefully this is sufficient to make my point clear.
