Class CloningSpecializer

java.lang.Object
  net.sf.composite.specialize.specializers.BaseSpecializer
      net.sf.composite.specialize.specializers.CloningSpecializer

All Implemented Interfaces:

Specializer

public class CloningSpecializer
extends BaseSpecializer

Specializes a composite by cloning it and then filtering out components that are not of the requested specializedType. Since this specializer relies on cloning, the original composite must implement the requested specializedType.

The main benefit of this specializer is performance. The main drawback is that the composite to be specialized must implement all of the interfaces to which it may be specialized.
