lexer.dat and parser.dat

[fidel....@gmail.com]

Hi, Ettienne!

I have always wondered why the lexer and parser tables have been moved to lexer.dat and parser.dat respectively. We can see the tables in the code commented out. But, was there a specific reason for moving them to these two external files? Was it for efficiency reasons?

Thanks in advance!

Hi Fidel,

It's to circumvent a limitation of class files. When lexer and parser tables get big, the static class initializer (which prefills tables with data) can't fit within the 64k method size limit of the class file format.

Have fun,

Etienne
