Constructor Detail
AbstractActionActorTXPNode
protected AbstractActionActorTXPNode()
Default constructor used by theAbstractJavaActionActor
constructor.
AbstractActionActorTXPNode
protected AbstractActionActorTXPNode(VSActionTXProcess actionProcess, SETTINGS settings)
Constructor for action actors.
Method Detail
createLogger
protected final void createLogger()
Overrides logger creation to set our own.- Overrides:
createLogger
in classAbstractTXPNode
setState
protected void setState(ITXPNode.State state)
Changes the node's state to the specified state. Any changes in the state will be logged.- Parameters:
state
- The new node state.
assignSettings
public final void assignSettings(VSActionTXProcess actionProcess, SETTINGS settings) throws java.lang.IllegalStateException
Called when the construction is performed of the node to assign the settings property container.This method is called by the framework and should not be called.
- Specified by:
assignSettings
in interfaceIActionActorSettingsReceiver<SETTINGS extends AbstractSettings>
- Parameters:
actionProcess
- The action process.settings
- The property container instance.- Throws:
java.lang.IllegalStateException
- If called outside of the framework.
getSettings
public final SETTINGS getSettings()
Gets the settings container. If this call is done in the constructor, it will return null.- Specified by:
getSettings
in interfaceIActionActorSettingsReceiver<SETTINGS extends AbstractSettings>
- Returns:
- The settings container, or null if not yet set. After constructor has been called, this value is non-null.
getActionProcess
public final VSActionTXProcess getActionProcess()
Gets the action transaction process.- Specified by:
getActionProcess
in interfaceIActionActorSettingsReceiver<SETTINGS extends AbstractSettings>
- Returns:
- The VSActionTXProcess instance invoking this Java Actor, or
null
if called in e.g. the constructor and the initialization using
has not yet been done.assignSettings(VSActionTXProcess, AbstractSettings)
getAction
public final VSAction getAction()
Gets the action associated with the VirtualSpace Action TXP process.- Specified by:
getAction
in interfaceIActionActorSettingsReceiver<SETTINGS extends AbstractSettings>
- Returns:
- The VSAction instance invoking this Java Actor, or
null
if called in e.g. the constructor and the initialization using
has not yet been done.assignSettings(VSActionTXProcess, AbstractSettings)
getVirtualSpace
public final VirtualSpace getVirtualSpace()
Gets the VirtualSpace for the process VirtualSpace Action TXP process.- Specified by:
getVirtualSpace
in interfaceIActionActorSettingsReceiver<SETTINGS extends AbstractSettings>
- Returns:
- The VirtualSpace instance invoking this Java Actor, or
null
if called in e.g. the constructor and the initialization using
has not yet been done.assignSettings(VSActionTXProcess, AbstractSettings)
getLoggerInfo
public final java.lang.String getLoggerInfo()
Gets the node information string.- Returns:
- Node information string information to pass to the logger output, or null for not yet initialized.
prepareAction
public final java.lang.Throwable prepareAction()
Method called to do the serialized preparation of the action actor.This method is called once all nodes are associated with the TXProcess and each node has processed "begin" successfully.
If this action fails preparation, the process is rolled back, and this is handled by the framework.
- Returns:
- null for success of the action prepare stage, otherwise the exception.
prepare
protected void prepare() throws java.lang.Exception
Action actor specific action needed for preparation. This method is called from the prepareAction.This method is overridden by the action actor as required.
- Throws:
java.lang.Exception
- For any error in the prepare phase.
executeAction
public final java.lang.Throwable executeAction()
Method called to do the serialized execution work of the action actor.This method is called once all nodes are associated with the TXProcess, each node has processed "begin" and "prepare" successfully.
- Returns:
- null for success of the action execution, otherwise the exception.
execute
public abstract void execute() throws java.lang.Exception
Method called to do the serialized work of the action actor. This method is called once all nodes are associated with the TXProcess and each node has processed "begin" successfully.This method must be implemented by the action actor.
- Throws:
java.lang.Exception
- For any error in the execution phase.
forget
public void forget(ITXProcess process)
Notifies the node it got disassociated from the process ie it can abort, rollback (if needed) and forget about the process.
cleanUp
protected final void cleanUp()
Cleans up once by calling
and then logs potential clean-up error. The node is then cleared of TXProcess references.onCleanup()
onCleanup
protected void onCleanup()
Called last to perform clean-up.Override this method to perform the required clean-up of resources, etc.
