Method Detail

getInetSocketAddress

public java.net.InetSocketAddress getInetSocketAddress()

Get the InetSocketAddress for the established connection.

Specified by:

getInetSocketAddress in interface RemoteEndpoint

Returns:

the InetSocketAddress for the established connection. (or null, if the connection is no longer established)

sendBytes

public void sendBytes(java.nio.ByteBuffer data)
               throws java.io.IOException

Blocking write of bytes.

Specified by:

sendBytes in interface RemoteEndpoint

Parameters:

data - the message to be sent

Throws:

java.io.IOException - if unable to send the bytes

sendBytesByFuture

public java.util.concurrent.Future<java.lang.Void> sendBytesByFuture(java.nio.ByteBuffer data)

Description copied from interface: RemoteEndpoint

Initiates the asynchronous transmission of a binary message. This method returns before the message is transmitted. Developers may use the returned Future object to track progress of the transmission.

Specified by:

sendBytesByFuture in interface RemoteEndpoint

Parameters:

data - the data being sent

Returns:

the Future object representing the send operation.

sendBytes

public void sendBytes(java.nio.ByteBuffer data,
                      WriteCallback callback)

Description copied from interface: RemoteEndpoint

Initiates the asynchronous transmission of a binary message. This method returns before the message is transmitted. Developers may provide a callback to be notified when the message has been transmitted or resulted in an error.

Specified by:

sendBytes in interface RemoteEndpoint

Parameters:

data - the data being sent

callback - callback to notify of success or failure of the write operation

uncheckedSendFrame

public void uncheckedSendFrame(WebSocketFrame frame,
                               WriteCallback callback)

sendPartialBytes

public void sendPartialBytes(java.nio.ByteBuffer fragment,
                             boolean isLast)
                      throws java.io.IOException

Description copied from interface: RemoteEndpoint

Send a binary message in pieces, blocking until all of the message has been transmitted. The runtime reads the message in order. Non-final pieces are sent with isLast set to false. The final piece must be sent with isLast set to true.

Specified by:

sendPartialBytes in interface RemoteEndpoint

Parameters:

fragment - the piece of the message being sent

isLast - true if this is the last piece of the partial bytes

Throws:

java.io.IOException - if unable to send the partial bytes

sendPartialString

public void sendPartialString(java.lang.String fragment,
                              boolean isLast)
                       throws java.io.IOException

Description copied from interface: RemoteEndpoint

Send a text message in pieces, blocking until all of the message has been transmitted. The runtime reads the message in order. Non-final pieces are sent with isLast set to false. The final piece must be sent with isLast set to true.

Specified by:

sendPartialString in interface RemoteEndpoint

Parameters:

fragment - the piece of the message being sent

isLast - true if this is the last piece of the partial bytes

Throws:

java.io.IOException - if unable to send the partial bytes

sendPing

public void sendPing(java.nio.ByteBuffer applicationData)
