IHandlePartFactory
IHandlePart
s for the given targets. As
additional information might be needed by the IHandlePartFactory
to identify the creation context, the initiating contextBehavior
is expected to pass in a reference to itself as well as a
contextMap.
The contextMap may either directly contain the additional information needed by the factory, or it may be used as a reference to identify the creation context, in case the factory needs to query back the initiating contextBehavior for such information.
This mechanism is needed because all IBehavior
s are expected to
be stateless, so only the information within the contextMap will
allow the contextBehavior to identify the respective creation
context. A contract between a (concrete) IBehavior
and a
(concrete) IHandlePartFactory
that is based on such a query may
be realized as follows:
List createHandleParts(List targets, IBehavior contextBehavior, Map<Object, Object> contextMap) { if (contextBehavior instanceof ConcreteBehavior) { SomeAdditionalInformation i = ((ConcreteBehavior) contextBehavior) .giveSomeAdditionalInformation(contextMap); ... } }
