Field Detail

state

public ConnectionState state

The current state of this Connection.

reason

public ErrorInfo reason

Error information associated with a connection failure.

key

public java.lang.String key

The assigned connection key.

recoveryKey

public java.lang.String recoveryKey

RTN16b) Connection#recoveryKey is an attribute composed of the connection key and latest serial received on the connection

id

public java.lang.String id

A public identifier for this connection, used to identify this member in presence events and message ids.

serial

public long serial

The serial number of the last message to be received on this connection.

connectionManager

public final ConnectionManager connectionManager

Method Detail

connect

public void connect()

Causes the library to re-attempt connection, if it was previously explicitly closed by the user, or was closed as a result of an unrecoverable error.

ping

public void ping(CompletionListener listener)

Send a heartbeat message to the Ably service and await a response.

Parameters:

listener: - a listener to be notified of the outcome of this message.

close

public void close()

Causes the connection to close, entering the closed state, from any state except the failed state. Once closed, the library will not attempt to re-establish the connection without a call to connect().

onConnectionStateChange

public void onConnectionStateChange(ConnectionStateListener.ConnectionStateChange stateChange)

apply

protected void apply(ConnectionStateListener listener,
                     ConnectionEvent event,
                     java.lang.Object... args)

Specified by:

apply in class EventEmitter<ConnectionEvent,ConnectionStateListener>

emitUpdate

public void emitUpdate(ErrorInfo errorInfo)

emit

                             ConnectionStateListener.ConnectionStateChange stateChange)

Deprecated.

on

@Deprecated
public void on(ConnectionState state,
                           ConnectionStateListener listener)

Deprecated.
