Class ReferenceDescriptor

java.lang.Object
  org.jbpm.util.DefaultObservable
      org.jbpm.wire.descriptor.AbstractDescriptor
          org.jbpm.wire.descriptor.ReferenceDescriptor

All Implemented Interfaces:

java.io.Serializable, Observable, Descriptor

public class ReferenceDescriptor
extends AbstractDescriptor
implements Descriptor

This Descriptor specifies a reference to an object. The object referenced should be declared somewhere else in the wireContext.

The constructed object is the referenced object.

The AbstractDescriptor.init field can be used to force initialization of the referenced object.

Method Detail

construct

public java.lang.Object construct(WireContext wireContext)

Description copied from interface: Descriptor

constructs the object.

Specified by:

construct in interface Descriptor

Parameters:

wireContext - WireContext in which the object is created. This is also the WireContext where the object will search for other object that may be needed during the initialization phase.

Returns:

the constructed object.

isDelayedInitializationAllowed

public boolean isDelayedInitializationAllowed()

setValue

public void setValue(java.lang.String objectName)
