Description copied from interface: WebSocket

This callback will be invoked when a text message has been received.

Specified by:

onMessage in interface WebSocket

Parameters:

text - the text received from the remote end-point.

Parameters:

code - the closing status code.

close

public void close(int code,
         String reason)

Description copied from interface: WebSocket

send

public Future<DataFrame> send(byte[] data)

Description copied from interface: WebSocket

Send a binary frame to the remote end-point.

Specified by:

send in interface WebSocket

Returns:

Future which could be used to control/check the sending completion state.

send

public Future<DataFrame> send(String data)

Description copied from interface: WebSocket

Send a text frame to the remote end-point.

Specified by:

send in interface WebSocket

Returns:

Future which could be used to control/check the sending completion state.

sendPing

public Future<DataFrame> sendPing(byte[] data)

Description copied from interface: WebSocket

Sends a ping frame with the specified payload (if any).

Specified by:

sendPing in interface WebSocket

Parameters:

data - optional payload. Note that payload length is restricted to 125 bytes or less.

Returns:

Future which could be used to control/check the sending completion state.

sendPong

public Future<DataFrame> sendPong(byte[] data)

Description copied from interface: WebSocket

Sends a ping frame with the specified payload (if any).

It may seem odd to send a pong frame, however, RFC-6455 states:

"A Pong frame MAY be sent unsolicited. This serves as a unidirectional heartbeat. A response to an unsolicited Pong frame is not expected."

Specified by:

sendPong in interface WebSocket

Parameters:

data - optional payload. Note that payload length is restricted to 125 bytes or less.

Returns:

Future which could be used to control/check the sending completion state.

stream

public Future<DataFrame> stream(boolean last,
                       String fragment)

Description copied from interface: WebSocket

Sends a fragment of a complete message.

Specified by:

stream in interface WebSocket

Parameters:

last - boolean indicating if this message fragment is the last.

fragment - the textual fragment to send.

Returns:

Future which could be used to control/check the sending completion state.

stream

public Future<DataFrame> stream(boolean last,
                       byte[] bytes,
                       int off,
                       int len)

Description copied from interface: WebSocket

Sends a fragment of a complete message.

Specified by:

stream in interface WebSocket

Parameters:

last - boolean indicating if this message fragment is the last.

bytes - the binary fragment to send.

off - the offset within the fragment to send.

len - the number of bytes of the fragment to send.

Returns:

Future which could be used to control/check the sending completion state.
