Class AbstractDecorator<S>

java.lang.Object
  org.ops4j.peaberry.util.AbstractDecorator<S>

All Implemented Interfaces:

ImportDecorator<S>

public abstract class AbstractDecorator<S>
extends Object
implements ImportDecorator<S>

Skeletal implementation to simplify development of ImportDecorators.

Developers only have to extend this class and provide an implementation of the decorate(Object, Map) method, which takes the original service instance and associated attribute map, and returns a decorated instance.
