Public Methods

Method	Description
AddEdge ( EdgeCreationWrapper ecw ) : void	A new underlying edge has been created, this is used to add the edge to the EdgeListener for handling and to wrap the edge.
CreateEdgeTo ( TransportAddress ta, EdgeCreationCallback ecb ) : void	This wraps the underlying CreateEdgeTo using EdgeCreationWrappers
Start ( ) : void	This is passed to the underlying EdgeListener. By default we do nothing to this.
Stop ( ) : void	This is passed to the underlying EdgeListener. By default we do nothing to this.
UpdateLocalTAs ( Edge e, TransportAddress ta ) : void	This is passed tothe underlying EdgeListener. By default we do nothing to this.
UpdateRemoteTAs ( IList list, Edge e, TransportAddress ta ) : void	This is passed tothe underlying EdgeListener. By default we do nothing to this.
WrapperEdgeListener ( EdgeListener el ) : System

Protected Methods

Method	Description
EdgeClose ( object o, EventArgs ea ) : void	This is called when one of our edges closes. This handles removing the state from the EdgeListener as necessary.
Finalize ( WrapperEdge wedge ) : void	When the edge is finally wrapped, this is called to finalize the adding of the edge to the edgelistner.
HandleEdgeCloseRequestEvent ( object el, EventArgs ea ) : void	This handles the RequestClose of the underlying edge. The convoluted model for handling edge closes is this... I) UEL calls RequestClose 1) Triggers HandleEdgeCloseRequestEvent 2) If there is a wrapper edge, call RequestClose on it 3) If there isn't a wrapper edge, we are forced to simply close the edge and send a failed ecw II) A wrapper edge is responsible for calling edge close on the wrapped edge on edge close III) if an wrapped edge calls close, we are notified via an event, that will send a failed ecw or close the wrapper edge
HandleEdgeEvent ( object edge, EventArgs ea ) : void	A new edge has been created! This comes from the underlying EL's SendEdgeEvent.
SendEdgeEventHelper ( bool success, Edge e, Exception x ) : void	This is a EdgeCallback used when to handle the cases for inbound edes. This executes SendEdgeEvent for this WEL.
WrapEdge ( Edge edge ) : void	This method is usd to wrap the edge.

Method Details

AddEdge() public method

A new underlying edge has been created, this is used to add the edge to the EdgeListener for handling and to wrap the edge.

public AddEdge ( EdgeCreationWrapper ecw ) : void
ecw	EdgeCreationWrapper
return	void

CreateEdgeTo() public method

This wraps the underlying CreateEdgeTo using EdgeCreationWrappers

public CreateEdgeTo ( TransportAddress ta, EdgeCreationCallback ecb ) : void
ta	TransportAddress
ecb	EdgeCreationCallback
return	void

EdgeClose() protected method

This is called when one of our edges closes. This handles removing the state from the EdgeListener as necessary.

protected EdgeClose ( object o, EventArgs ea ) : void
o	object
ea	System.EventArgs
return	void

Finalize() protected method

When the edge is finally wrapped, this is called to finalize the adding of the edge to the edgelistner.

protected Finalize ( WrapperEdge wedge ) : void
wedge	WrapperEdge
return	void

HandleEdgeCloseRequestEvent() protected method

This handles the RequestClose of the underlying edge.

The convoluted model for handling edge closes is this... I) UEL calls RequestClose 1) Triggers HandleEdgeCloseRequestEvent 2) If there is a wrapper edge, call RequestClose on it 3) If there isn't a wrapper edge, we are forced to simply close the edge and send a failed ecw II) A wrapper edge is responsible for calling edge close on the wrapped edge on edge close III) if an wrapped edge calls close, we are notified via an event, that will send a failed ecw or close the wrapper edge

protected HandleEdgeCloseRequestEvent ( object el, EventArgs ea ) : void
el	object
ea	System.EventArgs
return	void

HandleEdgeEvent() protected method

A new edge has been created! This comes from the underlying EL's SendEdgeEvent.

protected HandleEdgeEvent ( object edge, EventArgs ea ) : void
edge	object
ea	System.EventArgs
return	void

SendEdgeEventHelper() protected method

This is a EdgeCallback used when to handle the cases for inbound edes. This executes SendEdgeEvent for this WEL.

protected SendEdgeEventHelper ( bool success, Edge e, Exception x ) : void
success	bool
e	Edge
x	System.Exception
return	void

Start() public method

This is passed to the underlying EdgeListener. By default we do nothing to this.

public Start ( ) : void
return	void

Stop() public method

This is passed to the underlying EdgeListener. By default we do nothing to this.

public Stop ( ) : void
return	void

UpdateLocalTAs() public method

This is passed tothe underlying EdgeListener. By default we do nothing to this.

public UpdateLocalTAs ( Edge e, TransportAddress ta ) : void
e	Edge
ta	TransportAddress
return	void

UpdateRemoteTAs() public method

This is passed tothe underlying EdgeListener. By default we do nothing to this.

public UpdateRemoteTAs ( IList list, Edge e, TransportAddress ta ) : void
list	IList
e	Edge
ta	TransportAddress
return	void

WrapEdge() protected method

This method is usd to wrap the edge.

protected WrapEdge ( Edge edge ) : void
edge	Edge
return	void

WrapperEdgeListener() public method

public WrapperEdgeListener ( EdgeListener el ) : System
el	EdgeListener
return	System
