Brush-valued properties that turn into sampler-properties in the shader. Represents the image present in the initial state of the transition. A Dependency property as the backing store for Progress. Also used to represent the state of a transition from start to finish (range between 0 and 1). Creates a modifiable clone (deep copy) of the using its current values. Makes a deep copy of the transition effect. Implements CloneCurrentValue in Silverlight. A clone of current instance of transition effect. Updates the shader's variables to the default values. Gets or sets the Input variable within the shader. Gets or sets the OldImage variable within the shader. Gets or sets the Progress variable within the shader. Provides data about which objects were affected when resolving a name change. Helper class to handle the logic of resolving a TargetName into a Target element based on the context provided by a host element. Occurs when the resolved element has changed. Gets or sets the name of the element to attempt to resolve. The name to attempt to resolve. The resolved object. Will return the reference element if TargetName is null or empty, or if a resolve has not been attempted. Gets or sets the reference element from which to perform the name resolution. The reference element. Gets or sets a value indicating whether the reference element load is pending. True if [pending reference element load]; otherwise, False. If the Host has not been loaded, the name will not be resolved. In that case, delay the resolution and track that fact with this property. Attempts to update the resolved object from the name within the context of the namescope reference element. The old resolved object. Resets the existing target and attempts to resolve the current TargetName from the context of the current Host. If it cannot resolve from the context of the Host, it will continue up the visual tree until it resolves. If it has not resolved it when it reaches the root, it will set the Target to null and write a warning message to Debug output. The current version of the flow file schema. This number should be incremented whenever: A new _required_ field is added. The data type of a field is changed. The semantic interpretation of a field is changed. When upgrading the current schema number, you'll also need to take into account migration/upgrade strategies, and mechanisms for deserializing older schemas. In some cases, the same serializer data structure may suffice by applying different parsing validation rules. In other cases, a new data structure may be needed to deserialize the old format from disk. Represents an action that can be targeted to affect an object other than its AssociatedObject. The type constraint on the target. TargetedTriggerAction extends TriggerAction to add knowledge of another element than the one it is attached to. This allows a user to invoke the action on an element other than the one it is attached to in response to a trigger firing. Override OnTargetChanged to hook or unhook handlers on the target element, and OnAttached/OnDetaching for the associated element. The type of the Target element can be constrained by the generic type parameter. If you need control over the type of the AssociatedObject, set a TypeConstraintAttribute on your derived type. Initializes a new instance of the class. Gets the target object. If TargetName is not set or cannot be resolved, defaults to the AssociatedObject. The target. In general, this property should be used in place of AssociatedObject in derived classes. Called when the target property changes. Override this to hook and unhook functionality on the specified Target, rather than the AssociatedObject. The old target. The new target. Represents an action that can be targeted to affect an object other than its AssociatedObject. This is an infrastructure class. Action authors should derive from TargetedTriggerAction<T> instead of this class. Gets or sets the target object. If TargetObject is not set, the target will look for the object specified by TargetName. If an element referred to by TargetName cannot be found, the target will default to the AssociatedObject. This is a dependency property. The target object. Gets or sets the name of the object this action targets. If Target is set, this property is ignored. If Target is not set and TargetName is not set or cannot be resolved, the target will default to the AssociatedObject. This is a dependency property. The name of the target object. Gets the target object. If TargetObject is set, returns TargetObject. Else, if TargetName is not set or cannot be resolved, defaults to the AssociatedObject. The target object. In general, this property should be used in place of AssociatedObject in derived classes. The Target element does not satisfy the type constraint. Gets the associated object type constraint. The associated object type constraint. Define a TypeConstraintAttribute on a derived type to constrain the types it may be attached to. Gets the target type constraint. The target type constraint. Called when the target changes. The old target. The new target. This function should be overriden in derived classes to hook and unhook functionality from the changing source objects. Called after the action is attached to an AssociatedObject. Called when the action is being detached from its AssociatedObject, but before it has actually occurred. Represents an attachable object that encapsulates a unit of functionality. The type to which this action can be attached. Initializes a new instance of the class. Gets the object to which this is attached. The associated object. Gets the associated object type constraint. The associated object type constraint. Represents an attachable object that encapsulates a unit of functionality. This is an infrastructure class. Action authors should derive from TriggerAction<T> instead of this class. Gets or sets a value indicating whether this action will run when invoked. This is a dependency property. True if this action will be run when invoked; otherwise, False. Gets the object to which this action is attached. The associated object. Gets the associated object type constraint. The associated object type constraint. Gets or sets a value indicating whether this instance is attached. True if this instance is attached; otherwise, False. Attempts to invoke the action. The parameter to the action. If the action does not require a parameter, the parameter may be set to a null reference. Invokes the action. The parameter to the action. If the action does not require a parameter, the parameter may be set to a null reference. Called after the action is attached to an AssociatedObject. Called when the action is being detached from its AssociatedObject, but before it has actually occurred. When implemented in a derived class, creates a new instance of the derived class. The new instance. Gets the associated object. The associated object. Attaches to the specified object. The object to attach to. Cannot host the same TriggerAction on more than one object at a time. dependencyObject does not satisfy the TriggerAction type constraint. Detaches this instance from its associated object. Represents a collection of actions with a shared AssociatedObject and provides change notifications to its contents when that AssociatedObject changes. Initializes a new instance of the class. Internal, because this should not be inherited outside this assembly. Called immediately after the collection is attached to an AssociatedObject. Called when the collection is being detached from its AssociatedObject, but before it has actually occurred. Called when a new item is added to the collection. The new item. Called when an item is removed from the collection. The removed item. Creates a new instance of the TriggerActionCollection. The new instance. Represents an object that can invoke actions conditionally. The type to which this trigger can be attached. TriggerBase is the base class for controlling actions. Override OnAttached() and OnDetaching() to hook and unhook handlers on the AssociatedObject. You may constrain the types that a derived TriggerBase may be attached to by specifying the generic parameter. Call InvokeActions() to fire all Actions associated with this TriggerBase. Initializes a new instance of the class. Gets the object to which the trigger is attached. The associated object. Gets the type constraint of the associated object. The associated object type constraint. Argument passed to PreviewInvoke event. Assigning Cancelling to True will cancel the invoking of the trigger. This is an infrastructure class. Behavior attached to a trigger base object can add its behavior as a listener to TriggerBase.PreviewInvoke. Represents an object that can invoke Actions conditionally. This is an infrastructure class. Trigger authors should derive from Trigger<T> instead of this class. Gets the object to which the trigger is attached. The associated object. Gets the type constraint of the associated object. The associated object type constraint. Gets the actions associated with this trigger. The actions associated with this trigger. Event handler for registering to PreviewInvoke. Invoke all actions associated with this trigger. Derived classes should call this to fire the trigger. Called after the trigger is attached to an AssociatedObject. Called when the trigger is being detached from its AssociatedObject, but before it has actually occurred. Creates a new instance of the TriggerBase derived class. The new instance. Gets the associated object. The associated object. Attaches to the specified object. The object to attach to. Cannot host the same trigger on more than one object at a time. dependencyObject does not satisfy the trigger type constraint. Detaches this instance from its associated object. Represents a collection of triggers with a shared AssociatedObject and provides change notifications to its contents when that AssociatedObject changes. Initializes a new instance of the class. Internal, because this should not be inherited outside this assembly. Called immediately after the collection is attached to an AssociatedObject.
