Field Detail

DEFAULT_PORT

static final int DEFAULT_PORT

The default port of WebSockets, as defined in the spec. If the nullary constructor is used, DEFAULT_PORT will be the port the WebSocketServer is binded to. Note that ports under 1024 usually require root permissions.

Method Detail

close

void close(int code,
           java.lang.String message)

sends the closing handshake. may be send in response to an other handshake.

close

void close(int code)

close

void close()

Convenience function which behaves like close(CloseFrame.NORMAL)

closeConnection

void closeConnection(int code,
                     java.lang.String message)

This will close the connection immediately without a proper close handshake. The code and the message therefore won't be transfered over the wire also they will be forwarded to onClose/onWebsocketClose.

send

void send(java.lang.String text)
   throws java.nio.channels.NotYetConnectedException

Send Text data to the other end.

Throws:

java.lang.IllegalArgumentException

java.nio.channels.NotYetConnectedException

send

void send(java.nio.ByteBuffer bytes)
   throws java.lang.IllegalArgumentException,
          java.nio.channels.NotYetConnectedException

Send Binary data (plain bytes) to the other end.

Throws:

java.lang.IllegalArgumentException

java.nio.channels.NotYetConnectedException

send

void send(byte[] bytes)
   throws java.lang.IllegalArgumentException,
          java.nio.channels.NotYetConnectedException

Throws:

java.lang.IllegalArgumentException

java.nio.channels.NotYetConnectedException

sendFrame

void sendFrame(Framedata framedata)

hasBufferedData

boolean hasBufferedData()

getRemoteSocketAddress

java.net.InetSocketAddress getRemoteSocketAddress()

getLocalSocketAddress

java.net.InetSocketAddress getLocalSocketAddress()

isConnecting

boolean isConnecting()

isOpen

boolean isOpen()

isClosing

boolean isClosing()

isFlushAndClose

boolean isFlushAndClose()

Returns true when no further frames may be submitted
This happens before the socket connection is closed.

isClosed

boolean isClosed()

Returns whether the close handshake has been completed and the socket is closed.

getDraft

Draft getDraft()

getReadyState

WebSocket.READYSTATE getReadyState()

Retrieve the WebSocket 'readyState'. This represents the state of the connection. It returns a numerical value, as per W3C WebSockets specs.

Returns:

Returns '0 = CONNECTING', '1 = OPEN', '2 = CLOSING' or '3 = CLOSED'
