[antlr-interest] Lexer code missing @header info

[Bart Kiers]

Hi David,

The snippet:

@header {
package parser;
import java.util.HashMap;
}


is short for:

@parser::header {
package parser;
import java.util.HashMap;
}


You'll need to do the following as well:

@lexer::header {
package parser;
import java.util.HashMap;
}



Regards,

Bart.
