CachedSockets maintain a Socket member that is a reference to a Socket or Socket subclass. It defines and maintains the possible states of the socket. CachedSockets are maintained in a SocketCache for reuse. The Socket subclass passed into the CachedSocket constructor is the delegate object. The standard Socket responsibilities are passed to the delegate. Possible states the socket can be in is as follows: IDLE - defines the socket as ready for use ACTIVE - socket is currently in use CLOSED - marked to be closed Member variables _state - the current defined socket state _host - the host address the client socket will connect to _port - the port connected to _inputStream - the CSBufferedInputStream (Cached Socket BufferedInputStream) _socket - the 'real' socket class this CachedSocket represents _timer - starts when the socket is set to an IDLE state. If it times out, the socket deletes itself. author:    Kevin Hartig See Also:   SocketCache See Also:   CSBufferedInputStream Field Summary final public static  int ACTIVE      final public static  int CLOSED      final public static  int IDLE      Constructor Summary public   CachedSocket(Socket socket)      Constructor for CachedSocket.

Field Detail ACTIVE final public static int ACTIVE(Code) CLOSED final public static int CLOSED(Code) IDLE final public static int IDLE(Code) Constructor Detail CachedSocket public CachedSocket(Socket socket) throws IOException(Code) Constructor for CachedSocket. It defines the IP address the client socket will connect to and sets the initial state to IDLE. A CachedSocketFactory creates the proper type of Socket subclass to be passed into the CachedSocket constructor. Parameters:   socket - Defines the 'real' socket this class represents (the socketdelegate). exception:   IOException - throws IOException Method Detail close public synchronized void close() throws IOException(Code) Closes the socket and Removes the CachedSocket from the SocketCache exception:   IOException - throws IOException getInetAddress public InetAddress getInetAddress()(Code) Returns the address to which the socket is connected. the remote IP address to which this socket is connected. getInputStream public CSBufferedInputStream getInputStream()(Code) Get the CSBufferedInputStream associated with this socket. CSBufferedInputStream The input stream associated with thisCachedSocket getLocalAddress public InetAddress getLocalAddress()(Code) Gets the local address to which the socket is bound. getLocalPort public int getLocalPort()(Code) Returns the local port to which this socket is bound. getOutputStream public OutputStream getOutputStream() throws IOException(Code) Returns an output stream for this socket. the local port number to which this socket is connected. exception:   IOException - throws IOException getPort public int getPort()(Code) Returns the remote port to which this socket is connected. getSocket public Socket getSocket()(Code) getSocketCache public SocketCache getSocketCache()(Code) Get the socket cache where this CachedSocket is being stored. a reference to the SocketCache where this scoket is being stored. getState public synchronized int getState()(Code) Return the current socket state. int Returns the static value representing the current socketstate. getType public String getType()(Code) Get the type of socket. setActive public synchronized void setActive()(Code) Method used to define the socket ACTIVE meaning it's currently in use. setClosed public synchronized void setClosed()(Code) Method used to mark the socket ready to be closed and cleaned up. setIdle public synchronized void setIdle()(Code) Method used to define the socket IDLE indicating it's ready for use. Setting to IDLE state causes a timer to be started. If it times out, this socket will be cleaned up. This method uses the default timeout value set in the CachedSocketFactory.config setSocketCache public void setSocketCache(SocketCache socketCache)(Code) Set a reference to the Socket Cache so a CachedSocket knows how to remove itself from the cache. Parameters:   SocketCache - The cache where this CachedSocket is stored. setTimeout public synchronized void setTimeout(int timeout)(Code) Set the timeout value for the socket. Parameters:   timeout - The number of seconds the socket can stay alive while idle. setType public void setType(String socketType)(Code) Set the type of socket represented. timeOut public synchronized void timeOut()(Code) Implementation of the TimerClient interface method. If the socket is in the IDLE state and the idle timer expires, this method is called by the expired timer to clean up the socket. toString public String toString()(Code) Converts this socket to a String. For now, just the socket delegate representation. the String representation of the CachedSocket object Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
