clearAllState

public void clearAllState()

Description copied from interface: ActivityStateManager

Remove all previously registered RollbackHandlers for the current workflow

Specified by:

clearAllState in interface ActivityStateManager<T extends ProcessContext<?>>

clearRegionState

public void clearRegionState(String region)

Description copied from interface: ActivityStateManager

Remove all previously registered Rollbackhandlers for the current workflow labelled with the specified region

Specified by:

clearRegionState in interface ActivityStateManager<T extends ProcessContext<?>>

Parameters:

region - The region to which the scope of removal is limited

registerState

public void registerState(RollbackHandler<T> rollbackHandler,
                          Map<String,Object> stateItems)

Description copied from interface: ActivityStateManager

Register a RollbackHandler instance and some arbitrary state items with the StateManager. In the event of a rollbackAllState() call, the StateManager will execute all registered RollbackHandler instances. Note, Broadleaf does not try to wrap the RollbackHandler execution in a database transaction. Therefore, if the RollbackHandler implementation requires a database transaction (i.e. it's updating the database), then the implementer must supply it. The easiest way to achieve this is to register the RollbackHandler as a Spring bean and either use declaration in the app context xml, or use @Transactional annotations in the implementation itself. Then, inject the RollbackHandler into your activity and call registerState when appropriate.

Specified by:

registerState in interface ActivityStateManager<T extends ProcessContext<?>>

Parameters:

rollbackHandler - A RollbackHandler instance that should be executed by the StateManager

stateItems - Configuration items for the RollbackHandler (can be null)

registerState

public void registerState(Activity<T> activity,
                          T processContext,
                          RollbackHandler<T> rollbackHandler,
                          Map<String,Object> stateItems)

Description copied from interface: ActivityStateManager

Register a RollbackHandler instance and some arbitrary state items with the StateManager. In the event of a rollbackAllState() call, the StateManager will execute all registered RollbackHandler instances. Note, Broadleaf does not try to wrap the RollbackHandler execution in a database transaction. Therefore, if the RollbackHandler implementation requires a database transaction (i.e. it's updating the database), then the implementer must supply it. The easiest way to achieve this is to register the RollbackHandler as a Spring bean and either use declaration in the app context xml, or use @Transactional annotations in the implementation itself. Then, inject the RollbackHandler into your activity and call registerState when appropriate.

Specified by:

registerState in interface ActivityStateManager<T extends ProcessContext<?>>

Parameters:

activity - the current activity associated with the RollbackHandler (can be null)

processContext - the current ProcessContext associated with the activity (can be null)

rollbackHandler - A RollbackHandler instance that should be executed by the StateManager

stateItems - Configuration items for the RollbackHandler (can be null)

registerState

public void registerState(Activity<T> activity,
                          T processContext,
                          String region,
                          RollbackHandler<T> rollbackHandler,
                          Map<String,Object> stateItems)

Description copied from interface: ActivityStateManager

Register a RollbackHandler instance and some arbitrary state items with the StateManager. Can be used in conjunction with rollbackRegionState() to limit the scope of a rollback. Note, Broadleaf does not try to wrap the RollbackHandler execution in a database transaction. Therefore, if the RollbackHandler implementation requires a database transaction (i.e. it's updating the database), then the implementer must supply it. The easiest way to achieve this is to register the RollbackHandler as a Spring bean and either use declaration in the app context xml, or use @Transactional annotations in the implementation itself. Then, inject the RollbackHandler into your activity and call registerState when appropriate.

Specified by:

registerState in interface ActivityStateManager<T extends ProcessContext<?>>

Parameters:

activity - the current activity associated with the RollbackHandler (can be null)

processContext - the current ProcessContext associated with the activity (can be null)

region - Label this rollback handler with a particular name.

rollbackHandler - A RollbackHandler instance that should be executed by the StateManager

stateItems - Configuration items for the RollbackHandler (can be null)

rollbackAllState

public void rollbackAllState()
                      throws RollbackFailureException

Description copied from interface: ActivityStateManager

Cause the StateManager to call all registered RollbackHandlers

Specified by:

rollbackAllState in interface ActivityStateManager<T extends ProcessContext<?>>

Throws:

RollbackFailureException - if the rollback fails for some reason

rollbackRegionState

public void rollbackRegionState(String region)
                         throws RollbackFailureException

Description copied from interface: ActivityStateManager

Cause the StateManager to call all registered RollbackHandlers in the specified region.

Specified by:

rollbackRegionState in interface ActivityStateManager<T extends ProcessContext<?>>

Throws:

RollbackFailureException - if the rollback fails for some reason

getRollbackStateLocal

protected RollbackStateLocal getRollbackStateLocal()
