All Implemented Interfaces:

FlowExecutionRepository

Direct Known Subclasses:

AbstractConversationFlowExecutionRepository

public abstract class AbstractFlowExecutionRepository
extends java.lang.Object
implements FlowExecutionRepository

Abstract base class for flow execution repository implementations. Does not make any assumptions about the storage medium used to store active flow executions. Mandates the use of a FlowExecutionStateRestorer, used to rehydrate a flow execution after it has been obtained from storage from resume.

The configured FlowExecutionStateRestorer should be compatible with the chosen FlowExecution implementation and is configuration as done by a FlowExecutionFactory (listeners, execution attributes, ...).
