| Class | public final class DynamicBindingChain |
This class provides a wrapper implementation for the mx.bindings.utils API from which multiple objects within a Binding Chain can be managed and modified
| Property | Defined by | ||
|---|---|---|---|
| Host : Object [read-only]
Retrieves the host object which contains the property
which other objects in the Binding chain are bound
| DynamicBindingChain | ||
| Property : String [read-only]
Retrieves the property which objects added to the
Binding chain will be bound to
| DynamicBindingChain | ||
| Method | Defined by | ||
|---|---|---|---|
|
DynamicBindingChain(owner:Object, property:String)
Constructor
Creates a new DynamicBindingChain object and initializes
properties.
| DynamicBindingChain | ||
|
addHandlerToObject(instance:Object, handler:Function):void
Adds a handler function to an object which has been added
to the DynamicBindingChain instance which is invoked whenever
the value of the host property in the binding chain changes
| DynamicBindingChain | ||
|
addToBindingChain(instance:Object, property:String):void
Adds a new object to the current binding chain for
this DynamicBindingChain instance
| DynamicBindingChain | ||
|
getCurrentValue(instance:Object):Object
Retrieves the property value of each object which has been
added to the DynamicBindingChain instance
| DynamicBindingChain | ||
|
objectIsBound(instance:Object):Boolean
Determines if the object property of a bindable object
which has been added to the DynamicBindingChain instance
is currently bound to the value of the host property
| DynamicBindingChain | ||
|
objectsInChain():int
Determines the amount of objects currently added
to the Binding Chain
| DynamicBindingChain | ||
|
removeFromBindingChain(instance:Object):void
Removes binding from a dynamic bindable object property
which has been added to the DynamicBindingChain instance
| DynamicBindingChain | ||
| Host | property |
Host:Object [read-only]Retrieves the host object which contains the property which other objects in the Binding chain are bound
Implementation public function get Host():Object
| Property | property |
Property:String [read-only]Retrieves the property which objects added to the Binding chain will be bound to
Implementation public function get Property():String
| DynamicBindingChain | () | constructor |
public function DynamicBindingChain(owner:Object, property:String)Constructor Creates a new DynamicBindingChain object and initializes properties.
DynamicBindingChain objects can be used to wrap the mx.binding.utils API in order to manage the binding chain throughout the lifecycle of a DynamicBindingChain instance
Parametersowner:Object — owner of the properrty from which the
host object is to be bound
|
|
property:String — property that the newly binded property
will be bound
|
| addHandlerToObject | () | method |
public function addHandlerToObject(instance:Object, handler:Function):voidAdds a handler function to an object which has been added to the DynamicBindingChain instance which is invoked whenever the value of the host property in the binding chain changes
Parametersinstance:Object — instance which contains the bound property
|
|
handler:Function — which handles property change updates
|
| addToBindingChain | () | method |
public function addToBindingChain(instance:Object, property:String):voidAdds a new object to the current binding chain for this DynamicBindingChain instance
Parametersinstance:Object — host object from which to add a bindable
property. This object will be used as the
key for managing the ChangeWatcher instance
created by adding the dynamic binding
|
|
property:String — property on the host object which is to
be made bindable
|
| getCurrentValue | () | method |
public function getCurrentValue(instance:Object):ObjectRetrieves the property value of each object which has been added to the DynamicBindingChain instance
Parametersinstance:Object — instance which contains the bound property
|
Object — the current bound property value
|
| objectIsBound | () | method |
public function objectIsBound(instance:Object):BooleanDetermines if the object property of a bindable object which has been added to the DynamicBindingChain instance is currently bound to the value of the host property
Parametersinstance:Object — instance which contains the bound property
|
Boolean — true if binding has been added, otherwise false
|
| objectsInChain | () | method |
public function objectsInChain():intDetermines the amount of objects currently added to the Binding Chain
Returnsint — the length of the Binding Chain
|
| removeFromBindingChain | () | method |
public function removeFromBindingChain(instance:Object):voidRemoves binding from a dynamic bindable object property which has been added to the DynamicBindingChain instance
Parametersinstance:Object — instance which contains the bound property
