C# Class Rhino.Delegator

This is a helper class for implementing wrappers around Scriptable objects.

This is a helper class for implementing wrappers around Scriptable objects. It implements the Function interface and delegates all invocations to a delegee Scriptable object. The normal use of this class involves creating a sub-class and overriding one or more of the methods. A useful application is the implementation of interceptors, pre/post conditions, debugging.

Public Methods

Method	Description
Call ( Context cx, Scriptable scope, Scriptable thisObj, object args ) : object
Construct ( Context cx, Scriptable scope, object args ) : Scriptable	Note that if the `delegee` is `null`, this method creates a new instance of the Delegator itself rathert than forwarding the call to the `delegee`. Note that if the `delegee` is `null`, this method creates a new instance of the Delegator itself rathert than forwarding the call to the `delegee`. This permits the use of Delegator prototypes.
Delegator ( ) : System	Create a Delegator prototype. Create a Delegator prototype. This constructor should only be used for creating prototype objects of Delegator.
Delegator ( Scriptable obj ) : System	Create a new Delegator that forwards requests to a delegee Scriptable object. Create a new Delegator that forwards requests to a delegee Scriptable object.
Delete ( int index ) : void
Delete ( string name ) : void
Get ( int index, Scriptable start ) : object
Get ( string name, Scriptable start ) : object
GetClassName ( ) : string
GetDefaultValue ( Type hint ) : object	Note that this method does not get forwarded to the delegee if the `hint` parameter is null, `ScriptRuntime.ScriptableClass` or `ScriptRuntime.FunctionClass`. Note that this method does not get forwarded to the delegee if the `hint` parameter is null, `ScriptRuntime.ScriptableClass` or `ScriptRuntime.FunctionClass`. Instead the object itself is returned.
GetDelegee ( ) : Scriptable	Retrieve the delegee. Retrieve the delegee.
