Re: Rational argument for not using a preprocessor for Java?

Arne Vajh?j <arne@vajhoej.dk> writes:


  Sometimes I run Java code through a preprocessor.

  For example, I write the file ?Add.java? in the
  directory ?de/dclj/ram? as:

$include /java.gpp
$define VERSION slr@2009-08-29T17:35:33+02:00
$define SINCE slr@2007-08-30T01:17:50+02:00
HEADER
/**
REFERENCES */

@de.dclj.ram.meta.quality.Cleaned(2)
DECLARE(interface)< Domain >
{ public void add( final Domain value ); }

  The preprocessor generates from this:

public interface Add /* de.dclj.ram.Add */< Domain >
{ public void add( final Domain value ); }

  Thus, the preprocessor inserts some boilerplate and
  derives the name of the type declared from the file
  name.
