All Implemented Interfaces:
EventListener, IFocusComp, ILockUI, IMessageBox, IUIPanelAnimation, ICustomDataProvider, IGProp<GProp<?>[]>, IPropCnr, IVSComponent, IVSComponentListener, IVSComponentState, IVSMessageComponent, Cloneable
Direct Known Subclasses:
EditorVSAction
public class VSAction extends VSComponent implements IVSMessageComponent, ILockUI, IUIPanelAnimation
The VirtualSpace Action property class holds the property name, value and optionally has a parent and/or property listener(s).

VSAction has an array of PropReference's back to the linked data action property, and the order in this array is significant.

      public String getComponentIsDisabled()
      Gets the focus message for "Component is disabled" but for the component in question.
      Specified by:
      getComponentIsDisabled in class VSComponent

    • isAnimationPropPrivate

      public boolean isAnimationPropPrivate()
      Returns if the animation property is private or not.
      Specified by:
      isAnimationPropPrivate in interface IUIPanelAnimation
      Returns:
      Always false for VS actions.

    • onParentStateChanged

      public void onParentStateChanged(IVSComponent parent, IVSComponentState.State state, boolean stateValue)
      Invokes the parent state notification function for the component.
      Specified by:
      onParentStateChanged in interface IVSComponentListener
      Parameters:
      parent - The parent who's state was changed.
      state - The state that changed.
      stateValue - The new state value.

    • createActionActors

      protected ActionActors createActionActors()
      Creates a new instance of the action actors, overridden for the Editor.

    • addPredefinedProps

      protected void addPredefinedProps() throws PropException
      Adds the predefined properties for this container. This method is called once just after construction of the property container and sometimes population of it.

      The method should add properties to create or get reference to using the maybeAddProp method. When the PropCnr instance is cloned, the method getPredefinedProps() is called in order for the subclass to be able to retrieve the new instances to these properties, if stored in instance variables.

      Overrides:
      addPredefinedProps in class PropCnr
      Throws:
      PropException - for property exceptions.

    • getPredefinedProps

      protected void getPredefinedProps()
      Gets potential references to predefined properties for this container. This method is called once just after cloning of the property container.

      The method should get reference to using the getProp(...) methods. This allows the subclass to be able to retrieve the new instances to the properties created during addPredefinedProps() if stored in instance variables.

      Overrides:
      getPredefinedProps in class PropCnr

    • getActionActors

      public ActionActors getActionActors()
      Gets the action actors instance.
      Returns:
      The instance of the actors.

    • getTargetVirtualSpace

      public VSReference getTargetVirtualSpace()
      Gets the target VirtualSpace for operations.
      Returns:
      The target VirtualSpace if defined, otherwise the same VirtualSpace as the action.

    • addListener

      public boolean addListener(IVSActionListener listener)
      Adds a new listener to the VS action.
      Parameters:
      listener - The listener for VS action events.
      Returns:
      true for success, false if the listener already is added.

    • removeListener

      public boolean removeListener(IVSActionListener listener)
      Removes a listener from the VS action.
      Parameters:
      listener - The existing listener for VS action events.
      Returns:
      true for success, false if the listener has not been added.

    • onListenerChanged

      protected void onListenerChanged(IVSActionListener listener)
      Called when a listener is added or removed. This method is overridden by the Designer to update connections.

    • getActionListeners

      public IVSActionListener[] getActionListeners()
      Gets the listeners of the VS action events.
      Returns:
      A cached array of listeners for the value, retrieved without synchronization if possible.

    • onPrepare

      protected void onPrepare(IAppOwner appOwner, IModuleOwner moduleOwner, boolean isPostCall, List<Throwable> errors) throws PropException
      Called when the application is being prepared. The order of onPrepare calls is always parent first, the children. The method is called twice, first time with isPostCall set to false, then a second time with true.
      Overrides:
      onPrepare in class VSComponent
      Parameters:
      appOwner - The application owner.
      moduleOwner - The Module owner.
      isPostCall - Flag indicating this is a post-call.
      errors - A list of errors that occurred but did not cause an abort.
      Throws:

    • invokeExecute

      public String invokeExecute()
      Invokes and executes the action directly in the callers thread, regardless of the action settings.

      Note: This must be done with care: certain Action Actors may require its processing to run in a special thread that suites their purpose. If this thread happens to be the current caller thread, the operation may not succeed or hang.

      If not enabled or read-only, the method will fail with an error message. The same message will then also be logged as a warning,

      If this method is called from a Run Mode not being any of the Server Run Modes, the method will just log an informational message and return null

      Returns:
      null for success, otherwise an error message. The entire action TX process is performed before returning.

    • invokeExecute

      public String invokeExecute(IClientSessionGyro clientGyro)
      Invokes and executes the action directly in the callers thread, regardless of the action settings.

      Note: This must be done with care: certain Action Actors may require its processing to run in a special thread that suites their purpose. If this thread happens to be the current caller thread, the operation may not succeed or hang.

      If not enabled or read-only, the method will fail with an error message. The same message will then also be logged as a warning,

      If this method is called from a Run Mode not being any of the Server Run Modes, the method will just log an informational message and return null

      Parameters:
      clientGyro - Client gyro to use, null to look-it up if needed from current thread.
      Returns:
      null for success, otherwise an error message. The entire action TX process is performed before returning.
