Method Detail

getFlowModel

public FlowModel getFlowModel(java.lang.String id)
                       throws NoSuchFlowModelException

Description copied from interface: FlowModelLocator

Lookup the flow model with the specified id.

Specified by:

getFlowModel in interface FlowModelLocator

Parameters:

id - the flow model identifier

Returns:

the flow mode

Throws:

NoSuchFlowModelException - when the flow model with the specified id does not exist

setParent

public void setParent(FlowModelRegistry parent)

Description copied from interface: FlowModelRegistry

Sets this registry's parent registry. When asked by a client to locate a flow model this registry will query it's parent if it cannot fulfill the lookup request itself.

Specified by:

setParent in interface FlowModelRegistry

Parameters:

parent - the parent flow model registry, may be null

registerFlowModel

public void registerFlowModel(java.lang.String id,
                              FlowModelHolder modelHolder)

Description copied from interface: FlowModelRegistry

Register a flow model in this registry. Registers a "holder", not the Flow model itself. This allows the actual Flow model to be loaded lazily only when needed, and also rebuilt at runtime when its underlying resource changes without re-deploy.

Specified by:

registerFlowModel in interface FlowModelRegistry

Parameters:

id - the id to register the flow model under

modelHolder - a holder holding the flow model to register

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
