C# Class P2PStateServer.ServiceSocket

Represents an exception-safe wrapper of the .NET socket class. It exposes asynchronous methods and properties useful for state server soket operations.

The .NET Socket class is thread-safe but you can never be too careful. This class introduces an extra synchronization layer.

Public Methods

Method	Description
Abort ( ) : void	Terminates a connection
BeginConnect ( string Host, int Port, AsyncCallback ConnectCallBack, object StateObject ) : IAsyncResult	Begins an asynchronous Connect
BeginReceive ( int BufferLength, AsyncCallback ReadCallBack, object StateObject ) : IAsyncResult	Begins an asynchronous receive
CheckConnection ( ) : bool	Returns a value which indicates whether the socket is still connected. This method actively checks the connection status by sending a zero-sized payload packet to inbound sockets or calling Socket.Poll for outbound sockets.
Close ( ) : void	Closes the socket gracefully
EndConnect ( IAsyncResult ar ) : void	Ends an asynchronous Connect
EndReceive ( IAsyncResult ar, bool &Error ) : byte[]	Ends an asynchronous Receive
Equals ( object obj ) : bool
GetHashCode ( ) : int
Listen ( int Port, AsyncCallback AcceptCallback ) : Socket	Listens on a specified port on the machine
Send ( ResponseData Message ) : void	Sends data via the socket asynchronously
ServiceSocket ( Socket socket, bool IsPeerSocket, IBufferPool Buffers ) : System	Initializes a new instance of the ServiceSocket class.
ServiceSocket ( bool IsPeerSocket, IBufferPool Buffers ) : System	Initializes a new instance of the ServiceSocket class.

Method Details

Abort() public method

Terminates a connection

public Abort ( ) : void
return	void

BeginConnect() public method

Begins an asynchronous Connect

public BeginConnect ( string Host, int Port, AsyncCallback ConnectCallBack, object StateObject ) : IAsyncResult
Host	string	Host to connect to
Port	int	Port number to connect to
ConnectCallBack	AsyncCallback	Callback to call on connecting
StateObject	object	State object to pass to ConnectCallback
return	IAsyncResult

BeginReceive() public method

Begins an asynchronous receive

public BeginReceive ( int BufferLength, AsyncCallback ReadCallBack, object StateObject ) : IAsyncResult
BufferLength	int
ReadCallBack	AsyncCallback	Method to call on receiving data
StateObject	object	State object to be passed to ReadCallBack
return	IAsyncResult

CheckConnection() public method

Returns a value which indicates whether the socket is still connected.

This method actively checks the connection status by sending a zero-sized payload packet to inbound sockets or calling Socket.Poll for outbound sockets.

public CheckConnection ( ) : bool
return	bool

Close() public method

Closes the socket gracefully

public Close ( ) : void
return	void

EndConnect() public method

Ends an asynchronous Connect

public EndConnect ( IAsyncResult ar ) : void
ar	IAsyncResult	AsyncResult obtained from BeginConnect
return	void

EndReceive() public method

Ends an asynchronous Receive

public EndReceive ( IAsyncResult ar, bool &Error ) : byte[]
ar	IAsyncResult	AsyncResult obtained from BeginReive
Error	bool	Indicates an error occured while receiving data
return	byte[]

Equals() public method

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

GetHashCode() public method

public GetHashCode ( ) : int
return	int

Listen() public static method

Listens on a specified port on the machine

public static Listen ( int Port, AsyncCallback AcceptCallback ) : Socket
Port	int	Port number
AcceptCallback	AsyncCallback	Callback for accepting new connections
return	Socket

Send() public method

Sends data via the socket asynchronously

public Send ( ResponseData Message ) : void
Message	ResponseData	Data to transmit
return	void

ServiceSocket() public method

Initializes a new instance of the ServiceSocket class.

public ServiceSocket ( Socket socket, bool IsPeerSocket, IBufferPool Buffers ) : System
socket	Socket	The .NET Socket object to encapsulate
IsPeerSocket	bool	Indicates if this socket was spawned from the state server peer port
Buffers	IBufferPool
return	System

ServiceSocket() public method

Initializes a new instance of the ServiceSocket class.

public ServiceSocket ( bool IsPeerSocket, IBufferPool Buffers ) : System
IsPeerSocket	bool	Indicates if this socket was spawned from the state server peer port
Buffers	IBufferPool
return	System
