Class ObjectRef

java.lang.Object
  org.netbeans.api.registry.ObjectRef

---

public final class ObjectRef
extends Object

Identification of the object bound in a context. Object is identified by the context in which it is bound and by its binding name.

ObjectRef instance can be stored to Context by method Context.putObject(java.lang.String, java.lang.Object). There are two options for retrieval. Calling Context.getRef(java.lang.String) method on bound ObjectRef instance returns that instance. Calling Context.getObject(java.lang.String, java.lang.Object), however, will recursively dereference ObjectRef instance and return directly object the ObjectRef points to. If ObjectRef is invalid or referenced binding does not exist the ObjectRef instance is returned.
