 com.triactive.jdo.enhance.Enhancer
All known Subclasses: com.triactive.jdo.enhance.SunReferenceEnhancer,
| Enhancer | | abstract public class Enhancer (Code) | | Abstract class for JDO bytecode enhancement utility. The expected
command-line syntax is:
java com.triactive.jdo.enhance.Enhancer JDO-metadata-filename ...
Every class listed in the given metadata file(s) should be made persistence
capable via bytecode enhancement.
This class must be subclassed with an implementation that uses a working
bytecode enhancer. The key method that needs to be overridden and implemented
is callExternalEnhancer(String[]).
