public abstract class AbstractWrapper
extends Object
implements Cloneable

Base class of wrapper implementations. ObjectWrapper.wrap calls setTarget to pass the target object then create(), which the implementation must override. If create returns false an ObjectWrapperRTException is thrown from wrap.

The abstract wrapper implementations are created as prototypes and passed to ObjectWrapper, which clones them whenever one is needed.
