C# Class P2PStateServer.GetTransferMessage

Represents the GetTransferMessage message

The GetTransferMessage is broadcast to all connected peers when a peer wishes to receive a session resource from the network. The message is in turn forwarded to other peers that receive the message until tthe message traverses the network. If a peer receives this message and has the requested session resource, it proceeds to transfer the session resource to the peer that originated the broadcast. This message is only transmitted between peers.

Public Methods

Method	Description
Broadcast ( string OriginHost, List sockets, StateServer Service, string SessionKey, System.Guid MessageID, int MaxForwards, System.Guid BroadcastID ) : void	Sends a GetTransferMessage to a list of ServiceSockets
Broadcast ( string OriginHost, List sockets, StateServer Service, string SessionKey, System.Guid MessageID, int MaxForwards, System.Guid BroadcastID, System.DateTime TimeoutStamp, Action FoundAction, System TimeoutAction ) : void	Sends a GetTransferMessage to a list of ServiceSockets and queues an Action to be called if the requested session is transferred to this peer, and another Action to be called if no session is transferred after a set time.
Equals ( object obj ) : bool
Forward ( ) : void	Forwards this message to other peers on the network
GetHashCode ( ) : int
GetTransferMessage ( HTTPPartialData Data, StateServer Service ) : System	Initializes a new instance of the GetTransferMessage class
Process ( ) : void	Process the message
Rebroadcast ( ) : void	Rebroadcasts this message across the network. Rebroadcasts are different from Forwards because they have a different broadcast id and are also sent to the originating peer

Private Methods

Method	Description
CallExportEndedActions ( List Actions ) : void	Calls a list of Actions waiting to be processed after a session transfer is complete
CompleteTransferRequest ( ISessionObject Session, object StateObject ) : void	Called by the SessionDictionary.BeginExport method to complete processing the request, if the requested session was found and read
GetMergedHashCode ( System.Guid MessageID, System.Guid BroadcastID ) : int	Gets a hashcode value based on the combination of the message's ID and RebroadcastID
TransferFailure ( AsyncMessageTracker transferredMessage ) : void	Ends a failed Session Transfer
TransferSuccess ( AsyncMessageTracker transferredMessage ) : void	Ends a successful session transfer

Method Details

Broadcast() public static method

Sends a GetTransferMessage to a list of ServiceSockets

public static Broadcast ( string OriginHost, List sockets, StateServer Service, string SessionKey, System.Guid MessageID, int MaxForwards, System.Guid BroadcastID ) : void
OriginHost	string	The Host name of the peer that originally initiated this message
sockets	List	List of target ServiceSockets
Service	StateServer	Instance of state server
SessionKey	string	The requested session URI
MessageID	System.Guid	The unique message identifier
MaxForwards	int	The maximum number of nodes to forward the message to. This field is decremented by one for each forward
BroadcastID	System.Guid	The broadcast identifier. Used by peers to identify different broadcasts of the same message.
return	void

Broadcast() public static method

Sends a GetTransferMessage to a list of ServiceSockets and queues an Action to be called if the requested session is transferred to this peer, and another Action to be called if no session is transferred after a set time.

public static Broadcast ( string OriginHost, List sockets, StateServer Service, string SessionKey, System.Guid MessageID, int MaxForwards, System.Guid BroadcastID, System.DateTime TimeoutStamp, Action FoundAction, System TimeoutAction ) : void
OriginHost	string	The Host name of the peer that originally initiated this message
sockets	List	List of target ServiceSockets
Service	StateServer	Instance of state server
SessionKey	string	The requested session URI
MessageID	System.Guid	The unique message identifier
MaxForwards	int	The maximum number of nodes to forward the message to. This field is decremented by one for each forward
BroadcastID	System.Guid	The broadcast identifier. Used by peers to identify different broadcasts of the same message
TimeoutStamp	System.DateTime	The Time in UTC, at which point the message query is considered timed out
FoundAction	Action	The Action to be called if the requested session is transferred to this peer
TimeoutAction	System	The Action to be called if the requested session is not transferred to this peer after the TimeoutStamp time
return	void

Equals() public method

public Equals ( object obj ) : bool
obj	object
return	bool

Forward() public method

Forwards this message to other peers on the network

public Forward ( ) : void
return	void

GetHashCode() public method

public GetHashCode ( ) : int
return	int

GetTransferMessage() public method

Initializes a new instance of the GetTransferMessage class

public GetTransferMessage ( HTTPPartialData Data, StateServer Service ) : System
Data	HTTPPartialData	The HTTPPartialData class to load this instance from
Service	StateServer	State server instance
return	System

Process() public method

Process the message
