ConstructorsConstructorDescriptionPlasticClassPool
(ClassLoader parentLoader, PlasticManagerDelegate delegate, Set<String> controlledPackages, Set<TransformationOption> options) Creates the pool with a set of controlled packages; all classes in the controlled packages are loaded by the pool's class loader, and all top-level classes in the controlled packages are transformed via the delegate. -

PlasticClassPool
public PlasticClassPool(ClassLoader parentLoader, PlasticManagerDelegate delegate, Set<String> controlledPackages, Set<TransformationOption> options) Creates the pool with a set of controlled packages; all classes in the controlled packages are loaded by the pool's class loader, and all top-level classes in the controlled packages are transformed via the delegate.- Parameters:
parentLoader
- typically, the Thread's context class loaderdelegate
- responsible for end stages of transforming top-level classescontrolledPackages
- set of package names (note: retained, not copied)options
- used when transforming classes
