Public Methods

Method	Description
CanProxy ( ) : bool	Determines whether a proxy can be generated for the types given in the constructor.
DelegateDuckProxyType ( Type toDelegateType, Type fromDelegateType ) : System	Constructs an object.
Prepare ( ) : void	Prepares by generating the proxy type for the types given in the constructor.
WrapDuck ( Delegate duck ) : Delegate	Calls the static WrapDuck method of the generated proxy type to initialize a new instance of the proxy type with a given duck delegate and return a delegate to its invoke method.

Private Methods

Method	Description
GenerateProxyType ( ) : void	If a proxy type has not been generated yet, generates a proxy type that defines a method matching the method signature of the to delegate type given in the constructor which forwards calls to a delegate of the from type given in the constructor.
GetParameterTypes ( ParameterInfo parameters ) : System.Type[]	Utility to create an array of parameter types from an array of parameters.
ImplementInvokeMethod ( TypeBuilder proxyType, FieldInfo duckDelegateField ) : MethodBuilder	Implements the method of the proxy type that invokes the delegate given in its constructor.

Method Details

CanProxy() public method

Determines whether a proxy can be generated for the types given in the constructor.

return	bool

DelegateDuckProxyType() public method

Constructs an object.

public DelegateDuckProxyType ( Type toDelegateType, Type fromDelegateType ) : System
toDelegateType	System.Type	Type to be casted to.
fromDelegateType	System.Type	Type of delegate to be casted.
return	System

Prepare() public method

Prepares by generating the proxy type for the types given in the constructor.

WrapDuck() public method

Calls the static WrapDuck method of the generated proxy type to initialize a new instance of the proxy type with a given duck delegate and return a delegate to its invoke method.

public WrapDuck ( Delegate duck ) : Delegate
duck	System.Delegate	Duck delegate that the new proxy object should forward calls to.
return	System.Delegate
