meaningful equals and hashCode

[GoogleCodeExporter]

Is there a plan for a java_bean compiler option to build meaningful hashCode 
and equals methods?  This would be quite handy, and it's a feature I miss from 
the standard google implementation.

Not at the moment but you can certainly override java_bean by providing your 
own override_java_bean.stg that extends it.

The standard google impl hashes the descriptor as well as the field values.  In 
java land, only the field values are hashed.

I have an stg for this.  It seems to work well in my tests, but it will NOT 
work if you use the compiler option to generate primitive values.

I could not make a diff from these.  I'll review this and add the relevant 
parts as a generate_equals_hashcode option.

Thanks!

Implemented in version 1.3.2 (will be released soon).

Out of curiosity, did you use the above changes (eq_java_bean.java.stg)?

It was a surprise to see any movement on this 18 months after posting!
