Class GProp<VALUE>

Method Details

• dispose

  public final void dispose()

  Disposes of the property, but doesn't remove it from a parent. Calling the method more than once will result in a no-operation.

  All children of this property, if any, will also be disposed of.

  This method calls the onPropDispose() method.

  Specified by:

  dispose in interface IGProp<VALUE>

• isDisposed

  public final boolean isDisposed()

  Checks if the property is disposed.

  Specified by:

  isDisposed in interface IGProp<VALUE>

  Returns:

  true if property is disposed of, false otherwise.

• finalize

  protected void finalize() throws Throwable

  Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

  When called, the property is disposed of.

  Overrides:

  finalize in class Object

  Throws:

  Throwable - For finalizer errors.

• post

  public void post(Runnable runnable)

  Post a runnable for invocation at a later stage by the worker thread (or SWT thread for the Designer).

  Parameters:

  runnable - The runnable.

• post

  public void post(Worker worker, Runnable runnable)

  Post a runnable for invocation at a later stage by the worker thread (or SWT thread for the Designer if the worker parameter is null).

  In the server, this call MUST be done from a virtualized property if the worker is null. The worker used is the application session worker.

  Parameters:

  worker - The worker to use, null for default.

  runnable - The runnable.

• getAppWorker

  public Worker getAppWorker()

  Gets the application session worker.

  Do not abuse of this method (save the reference to the worker) as it requires a little look-up work to get the application session gyro.

  Returns:

  The application session worker, or null if the AppSessionGyro is not found (e.g. called from Designer or not a virtualized property).

  Throws:

  IllegalStateException - If called in the server and the AppSessionGyro cannot be retrieved AND the property is virtualized.

• getClientWorker

  public Worker getClientWorker()

  Gets the client session worker.

  Do not abuse of this method (save the reference to the worker) as it requires a little look-up work to get the client session gyro.

  Returns:

  The client session worker, or null if the ClientSessionGyro is not found (e.g. called from Designer or not a virtualized property).

  Throws:

  IllegalStateException - If called in the server and the ClientSessionGyro cannot be retrieved AND the property is virtualized.

• getListeners

  public EventListener[] getListeners()

  Gets the listeners.

  Returns:

  A new array of event listeners, never null.

• getTreeLock

  public final Object getTreeLock()

  Gets the tree-lock object used when locking the property tree when structural changes are made or when creating/reading transactions that could potentially cause a structural change. Code synchronized on a single property should not synchronize on the tree, it must synchronize on the tree first, then the property itself.

  Specified by:

  getTreeLock in interface IGProp<VALUE>

  Returns:

  The tree lock object, perhaps asking the parent for it until the root is found. This call is quite expensive in terms of CPU and should be avoided if possible.

• isPropClientCreated

  public final boolean isPropClientCreated()

  Checks if this property is created on the client or not.

  Specified by:

  isPropClientCreated in interface IGProp<VALUE>

  Returns:

  true for the client, false for server or editor.

• onPropInvalidateCache

  protected void onPropInvalidateCache()

  Invalidates a potential cache in this property. This method is called during a synchronized state of the property. Subclasses override this method to provide a robust caching mechanism.

• resolveRuntimeReferences

  public void resolveRuntimeReferences(IRuntimeResolver resolver)

  Called before transactions are prepared for sending. This method allows creation of e.g. runtime references such as Styles or Panel references that adds a virtual instance for the Client.

  This call is propagated in the entire client tree.

  Specified by:

  resolveRuntimeReferences in interface IGProp<VALUE>

  Parameters:

  resolver - The reference resolver.

• getValueClasses

  public abstract Class<?>[] getValueClasses()

  Gets the list of possible native Java classes that can be used to set a value using setPropertyValue, in order of importance. Note that loss of precision in data if e.g. an Float property accepts a Double. However, the setPropertyValue throws IllegalArgumentException if the range in invalid, e.g. conversion of a Integer to a Byte, and the value is not -127 to 128.

  Specified by:

  getValueClasses in interface IGProp<VALUE>

  Returns:

  The array of Java classes that can be accepted in the setPropertyValue method. The first type is the "native" or most preferred type. The array is at least one item in length and never null.

• clone

  public GProp<VALUE> clone() throws CloneNotSupportedException

  Creates a clone out of this property. The cloning is overridden by the super classes in order to handle cloning of its class variables appropriately.

  Cloning is used for "virtualization" of a property tree in the server. Client property classes will therefore throw CloneNotSupportedException.

  Once a tree has been cloned, the change-flag is reset, and the create-flag is set. All listeners are also removed! The new cloned property is an orphan, i.e. has no parent set.

  Note that the cloning process is done WITHOUT thread synchronization for performance reasons, thus no modifications should be done to the tree!

  Overrides:

  clone in class Object

  Throws:

  CloneNotSupportedException - If a subclass doesn't allow cloning, e.g. the client properties.

• 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.

  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:

  PropException - For property errors during the application preparation to need to abort.

• isPropVirtualizing

  protected boolean isPropVirtualizing()

  Checks if currently virtualizing during a clone operation.

  Returns:

  true during the virtualization process, false otherwise (also when virtualization has completed).

• virtualize

  protected GProp<VALUE> virtualize(IAppSessionGyro appGyro, IClientSessionGyro clientGyro, VirtualSpace virtualSpace) throws CloneNotSupportedException, PropException

  Call this method to "virtualize" a property tree. This method is used at runtime in the Server for the application session of virtual instances of VirtualSpace, but also virtual instances of panels, for the individual client session. The VirtualSpace is virtualized once for the application session and is shared for parallel client sessions.

  This method is similar to cloning, but enables references that are already resolved to remain if they point to a shared instance, e.g. the VirtualSpace pointing to its participants in the application property container shared instance, or a panel with references to text IDs, assets, etc.

  It is up to the property class to handle this by overriding this method.

  Parameters:

  appGyro - The application gyro instance performing the virtualization.

  clientGyro - The client gyro session, can be null if not initialized from the client gyro.

  virtualSpace - The virtualized VirtualSpace.

  Returns:

  The virtualized property.

  Throws:

  CloneNotSupportedException - If a subclass doesn't allow cloning, e.g. the client properties.

  PropException - For property errors during the virtualization.

  IllegalStateException - IllegalStateException if the property is in an invalid state, e.g. in virtualizing state.

• onVirtualizationCompleted

  protected void onVirtualizationCompleted(IAppSessionGyro appGyro, IClientSessionGyro clientGyro, VirtualSpace virtualSpace, boolean isPostResolve)

  Called when virtualization completed.

  Overriding classes must call super.onVirtualizationCompleted(IAppSessionGyro appGyro,IClientSessionGyro clientGyro,VirtualSpace virtualSpace,boolean isPostResolve) if they override this method.

  This method is called to the entire tree of the newly virtualized property container.

  Parameters:

  appGyro - The application gyro instance performing the virtualization.

  clientGyro - The client gyro session, can be null if not initialized from the client gyro.

  virtualSpace - The virtualized VirtualSpace.

  isPostResolve - Flag indicating this call is done after references are attempted to be resolved.

• getAppSessionGyro

  public IAppSessionGyro getAppSessionGyro()

  Returns the Application Session Gyro instance of this virtualized property.

  To get the IAppSessionGyro instance from the current thread use IAppSessionGyro.getSessionInstance(), or IAppSessionGyro.getSessionInstance(SessionInfo) to get it from the session information instance.

  Do not abuse of this method as it requires a little look-up work.

  Specified by:

  getAppSessionGyro in interface IGProp<VALUE>

  Returns:

  The Application Session Gyro if this instance is virtualized, null otherwise.

• getClientSessionGyro

  public IClientSessionGyro getClientSessionGyro()

  Returns the Client Session Gyro instance of this virtualized property. This method only work for properties in a panel tree. Data connectors may sometimes also provide IClientSessionGyro support.

  To get the IClientSessionGyro instance from the current thread use IClientSessionGyro.getSessionInstance(), or IClientSessionGyro.getSessionInstance(SessionInfo) to get it from the session information instance.

  Do not abuse of this method as it requires a little look-up work.

  Specified by:

  getClientSessionGyro in interface IGProp<VALUE>

  Returns:

  The Client Session Gyro if this instance is virtualized and is in a UIPanelBase (panels) tree (or for certain data connectors), null otherwise.
