  Flags one method in the class as receiving Frame events from the WebSocket implementation after they have been processed by any extensions declared during the Upgrade handshake.

• isConnecting

  public boolean isConnecting()

  Checks if the connection is connecting.

  Specified by:

  isConnecting in interface IWebSocketComm

  Returns:

  true if the connection is pending.

• isConnected

  public boolean isConnected()

  Checks if the connection is established.

  Specified by:

  isConnected in interface IWebSocketComm

  Returns:

  true if the connection is established.

• isClosing

  public boolean isClosing()

  Checks if the connection is currently closing.

  Specified by:

  isClosing in interface IWebSocketComm

  Returns:

  true if not closed, but closing.

• isClosed

  public boolean isClosed()

  Checks if the connection is disposed of.

  Specified by:

  isClosed in interface IWebSocketComm

  Returns:

  true if closed, not closing.

• close

  public void close()

  Call this method to close the socket.

  Specified by:

  close in interface IWebSocketComm

• close

  public void close(int code, String reason)

  Call this method to close the socket.

  Specified by:

  close in interface IWebSocketComm

  Parameters:

  code - A close code: zero for none, otherwise a code 1000 or range 3000 to 4999.

  reason - The reason code: if code is zero, null applies.

• close

  public boolean close(boolean rightNow)

  Call this method to close the socket.

  Specified by:

  close in interface IWebSocketComm

  Parameters:

  rightNow - If true, the socket is hard-closed, i.e. no close conversation takes place with the server. If false, the client will send a close message to server that replies with a close itself, then the socket is closed.

  Returns:

  true if closed, false if already closed.

• setSubProtocol

  public void setSubProtocol(String subProtocol) throws IllegalStateException

  Assigns a sub-protocol for the WebSocket (in case the processing of sub-protocol negotiation is done e.g. outside the WebSocket communication acceptor).

  Specified by:

  setSubProtocol in interface IWebSocketComm

  Throws:

  IllegalStateException - If the state doesn't permit this operation, or if the implementation doesn't allow it.

• getSubProtocol

  public String getSubProtocol()

  Gets the negotiated and accepted sub-protocol, null for none (yet), or none is provided by the parties (server or client).

  Specified by:

  getSubProtocol in interface IWebSocketComm

  Returns:

  The String for the sub-protocol negotiated, null for none.

• areBinaryDataFramesSupported

  public boolean areBinaryDataFramesSupported()

  Checks if Binary Data Frames are supported.

  Specified by:

  areBinaryDataFramesSupported in interface IWebSocketComm

  Returns:

  true if it is supported, false otherwise.

• send

  public void send(byte[] data) throws IOException

  Sends binary data.

  Specified by:

  send in interface IWebSocketComm

  Parameters:

  data - The byte array containing the data.

  Throws:

  IOException - for failures, e.g. socket is closed, not open, not connected.

• send

  public void send(String data) throws IOException

  Sends a String of data.

  Specified by:

  send in interface IWebSocketComm

• sendHeartBeat

  public boolean sendHeartBeat() throws IOException

  Throws:

  IOException - For send failures.

• getRemoteAddr

  public String getRemoteAddr()

  Returns:

  a String containing the IP address of the client that sent the request.

• getRemoteHost

  public String getRemoteHost()
