Method Detail

setParent

void setParent(FlowModelRegistry parent)

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.

Parameters:

parent - the parent flow model registry, may be null

registerFlowModel

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

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.

Parameters:

id - the id to register the flow model under

modelHolder - a holder holding the flow model to register
