A transitionable state that spawns a subflow when executed. When the subflow
this state spawns ends, the ending result is used as grounds for a state
transition out of this state.
A subflow state may be configured to map input data from its flow -- acting
as the parent flow -- down to the subflow when the subflow is spawned. In
addition, output data produced by the subflow may be mapped up to the parent
flow when the subflow ends and the parent flow resumes. See the
FlowAttributeMapper interface definition for more information on how
to do this. The logic for ending a subflow is located in the EndState
implementation.
