Constructor Detail

• GProp

  protected GProp()

  Creates a generic property. This constructor should only be used by the PropertyManager, but as the call is dynamically processed, an empty constructor is easiest to handle.

  Once the property is created, the initialize(String name) method should be called.

• GProp

  protected GProp​(Atom propertyAtom)

  Creates a generic property with the specified name with a null value. The initialize method must then be called.

  Parameters:

  propertyAtom - the property atom.

Method Detail

• 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 java.lang.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 java.lang.Object

  Throws:

  java.lang.Throwable - For finalizer errors.

• post

  public void post​(java.lang.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,
                   java.lang.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:

  java.lang.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:

  java.lang.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 java.lang.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 java.lang.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<?> clone()
                 throws java.lang.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 java.lang.Object

  Throws:

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

• extendsClone

  public GProp<?> extendsClone()
                        throws java.lang.CloneNotSupportedException

  Creates a clone out of this property for the Extends Framework. It is basically the same method as clone, except that every property is marked as Extended (can be checked by isPropExtended()), and property container do not clone the Extends Private properties (that return true to isPropExtendsPrivate()).

  Returns:

  The cloned property according to the rules specified above.

  Throws:

  java.lang.CloneNotSupportedException

• onPrepare

  protected void onPrepare​(IAppOwner appOwner,
                           IModuleOwner moduleOwner,
                           boolean isPostCall,
                           java.util.List<java.lang.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<?> virtualize​(IAppSessionGyro appGyro,
                                IClientSessionGyro clientGyro,
                                VirtualSpace virtualSpace,
                                PropCnr virtualizedProp)
                         throws java.lang.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.

  virtualizedProp - The property being virtualized.

  Returns:

  The virtualized property.

  Throws:

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

  PropException - For property errors during the virtualization.

                               VirtualSpace virtualSpace,
                               PropCnr virtualizedProp,
                               GProp<?> clonedProp)
                        throws PropException

  Called when this property has been virtualized.

  Override to perform required processing.

  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.

  virtualizedProp - The property being virtualized.

  clonedProp - The property that is cloned to produce this virtualized property.

  Throws:

  PropException - For property errors during the virtualization.

  Parameters:

  oldValue - The old value.

• modifyPropValue

  protected int modifyPropValue​(java.lang.Object oldValue,
                                java.lang.Object newValue,

                         throws PropException

  Called when setting a new value for this property. This method is normally not overridden by subclasses, but e.g. for properties containing arrays, this may be handled here, in order not modify the "oldValue" (such as an array, but rather to change it with the data from the "newValue").

  Parameters:

  oldValue - The old value.

  newValue - The new value.

  propMgr - The property manager for remote change, null for local.

  Returns:

  1 for value has changed, 0 for same value as current value, -1 for not processed. 2 can also be returned to indicate the current value has been modified with new contents. This is e.g. the case for the StringMapProp.

  Parameters:

  newValue - The new value to set.

  Throws:

  PropException - when the new value doesn't validate correctly.

  Parameters:

  newValue - The new value to set.

  Throws:

  PropTypeException - when the new value isn't of the correct class.

• validatePropValue

  public void validatePropValue​(java.lang.Object newValue)
                         throws PropException

  Validates the value to set. Subclasses can override this method to perform optional value validation. No validation is performed in this method.

  Note: When this method is called, synchronization is done at the property itself, so no synchronization on the tree should be done.

  public int getPropExtendsFlags()

  Checks if this property extends another property, and if so gets the extends flags. This call is only interesting to do in the Designer where the Extends Framework is used. It requires a little processing, so do not call it too often if not required.

  Specified by:

  getPropExtendsFlags in interface IGProp<VALUE>

  Returns:

  A value with the flags in the bit-values below:

  • EXT_EXTENDED - Extended property.
  • EXT_PRIVATE - Private Extends.
  • EXT_FINAL - Final Extends.
  • EXT_OVERRIDES - Overrides a source property.
  • EXT_OVERRIDES_FINAL_ERR - Overrides a source property that is final = error.

  For containers, these two bit values also apply:

  • EXT_CONTAINER_EXTENDS - Container extends another container (only for containers)
  • EXT_CONTAINER_EXTENDS_VALID - Container extends another container, and reference is valid (only for containers).

  Returns:

  the parameter string of this event.

• paramValue

  protected java.lang.String paramValue​(java.lang.Object value)

  Formats the value as a string to add to paramString. The default is to do "value.toString()" if value is not null, otherwise "[null]" is returned.

• toString

  public java.lang.String toString()

  Returns a string representation of this component and its values.

  Overrides:

  toString in class java.lang.Object

                                 int how)

  Processes error property verification. The default processing is to verify the two error properties pe1 and pe2 for equality if includeErrors is 0 or 1, and returns true if the value is 2=no comparison with error properties.

  Override to verify property errors for reference properties.

  Parameters:

  pe1 - The first error property, may be null.

  pe2 - The second error property, may be null.

  how - Flags EQC_* values for equal checking.

  Parameters:

  otherPropValue - The value to compare with.

  Returns:

  true if the values are equal, false otherwise.

• equalsTree

  protected java.lang.Object equalsTree​(PropCnr pc,
