Method Details

createUpgradeRequest

UpgradeRequest createUpgradeRequest(ClientEngine.TimeoutHandler timeoutHandler)

Create upgrade request and register ClientEngine.TimeoutHandler.

Parameters:

timeoutHandler - handshake timeout handler. ClientEngine.TimeoutHandler.handleTimeout() is invoked if processResponse(UpgradeResponse, Writer, Connection.CloseListener) is not called within handshake timeout.

Returns:

request to be send on the wire or null, when the request cannot be created. When null is returned, client should free all resources tied to current connection.

processResponse

ClientEngine.ClientUpgradeInfo processResponse(UpgradeResponse upgradeResponse,
 Writer writer,
 Connection.CloseListener closeListener)

Process handshake and return ClientEngine.ClientUpgradeInfo with handshake status (ClientEngine.ClientUpgradeStatus).

Parameters:

upgradeResponse - response to be processed.

writer - used for sending dataframes from client endpoint.

closeListener - will be called when connection is closed, will be set as listener of returned Connection.
