Method Detail

setExecutionAttributes

public void setExecutionAttributes(AttributeMap executionAttributes)

Sets the attributes to apply to flow executions created by this factory. Execution attributes may affect flow execution behavior.

Parameters:

executionAttributes - flow execution system attributes

setExecutionListenerLoader

public void setExecutionListenerLoader(FlowExecutionListenerLoader executionListenerLoader)

Sets the strategy for loading listeners that should observe executions of a flow definition. Allows full control over what listeners should apply for executions of a flow definition.

setExecutionKeyFactory

public void setExecutionKeyFactory(FlowExecutionKeyFactory executionKeyFactory)

Sets the strategy for generating flow execution keys for persistent flow executions.

createFlowExecution

public FlowExecution createFlowExecution(FlowDefinition flowDefinition)

Description copied from interface: FlowExecutionFactory

Create a new flow execution product for the given flow definition.

Specified by:

createFlowExecution in interface FlowExecutionFactory

Parameters:

flowDefinition - the flow definition

Returns:

the new flow execution, fully initialized and awaiting to be started

restoreFlowExecution

public FlowExecution restoreFlowExecution(FlowExecution flowExecution,
                                 FlowDefinition flowDefinition,
                                 FlowExecutionKey flowExecutionKey,
                                 MutableAttributeMap conversationScope,
                                 FlowDefinitionLocator subflowDefinitionLocator)

Description copied from interface: FlowExecutionFactory

Restore the transient state of the flow execution.

Specified by:

restoreFlowExecution in interface FlowExecutionFactory

Parameters:

flowExecution - the flow execution, newly deserialized and needing restoration

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

flowExecutionKey - 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
