public class InstrumentTask
extends BasicInstrumentationTask

An Ant task for instrumenting persistent classes in order to enable field-level interception using CGLIB.

In order to use this task, typically you would define a a taskdef similiar to:

where lib.class.path is an ANT path reference containing all the required Hibernate and CGLIB libraries.

And then use it like:

...

where the nested ANT fileset includes the class you would like to have instrumented.

Optionally you can chose to enable "Extended Instrumentation" if desired by specifying the extended attriubute on the task:

...

See the Hibernate manual regarding this option.
