Update of /cvsroot/hibernate/Hibernate/cirrus/hibernate/tools/codegen
In directory sc8-pr-cvs1:/tmp/cvs-serv29617/cirrus/hibernate/tools/codegen
Modified Files:
Generator.java Field.java ClassMapping.java BasicRenderer.java
Log Message:
* CodeGenerator Improvements:
- fixed some problems with composite-ids
- composite-id classes now implement equals(), hashCCode()
- all generated classes implement toString()
* Use ObjectUtil.equals() in a bunch of places
