Class StickyDecorator<S>

java.lang.Object
  org.ops4j.peaberry.util.decorators.StickyDecorator<S>

All Implemented Interfaces:

ImportDecorator<S>

public final class StickyDecorator<S>
extends Object
implements ImportDecorator<S>

An ImportDecorator that caches the first valid service instance and uses that until it becomes invalid. The decorator then calls the reset task to see if it should reset the cache and get a new service instance.

If no reset task is provided, the service instance cache is never reset.

Note: sticky decorators only really make sense for single services.
