restoreState(FlowExecution execution, FlowDefinition definition, FlowExecutionKey key, MutableAttributeMap<java.lang.Object> conversationScope, FlowDefinitionLocator subflowDefinitionLocator) Restore the transient state of the flow execution.

Method Detail

restoreState

FlowExecution restoreState(FlowExecution execution,
                           FlowDefinition definition,
                           FlowExecutionKey key,
                           MutableAttributeMap<java.lang.Object> conversationScope,
                           FlowDefinitionLocator subflowDefinitionLocator)

Restore the transient state of the flow execution.

Parameters:

execution - the flow execution, newly deserialized and needing restoration

definition - the root flow definition for the execution, typically not part of the serialized form

key - the flow execution key, typically not part of the serialized form

conversationScope - the execution's conversation scope, which is typically not part of the serialized form since it could be shared by multiple physical flow execution copies all sharing the same logical conversation

subflowDefinitionLocator - for locating the definitions of any subflows started by the execution

Returns:

the restored flow execution
