------------------------------------
Hi Richard,
There is no way of knowing the "enhance date".
Things like "methodsAdded", "bytesAdded" etc should only ever be returnable
from enhanceXXX() rather than as a separate method; it is the enhance process
that would define these.
Presumably "enhanceVendor" is to return the vendor name of the enhancer being
used?
I don't see the need for
public Class enhance(String className);
since
void enhanceClasses(String... classNames);
provides that.
Similarly the signature "enhance(String className, File jdoConfigFile);" since
the class name implies the location of the config file (JDO compliant locations
in the CLASSPATH).
What is "JDO configuration" ? Why would you set it ?

> URL: https://issues.apache.org/jira/browse/JDO-591
> Project: JDO
> Issue Type: New Feature
> Components: api2
> Reporter: Andy Jefferson
> Assignee: Andy Jefferson
> Fix For: JDO 2 maintenance release 3
>
>
> Having a standard interface to invoke the enhancer makes a lot of sense so we
> can have interchangeability of enhancers (for implementations that support
> BinaryCompatibility).
> A start point (for discussions) could be
> java -cp classpath {enhancer-class} [options] [jdo-files] [class-files]
> where options can be
> -persistenceUnit persistence-unit-name : Name of a "persistence-unit"
> to enhance the classes for
> -d target-dir-name : Write the enhanced classes to the specified
> directory
> -checkonly : Just check the classes for enhancement status
> -v : verbose output
> This then allows enhancement of the specified classes, or the classes defined
> by the specified JDO files, or the classes defined by the specified
> persistence-unit.
> What other control would people like to see ?
