public interface ReconnectionStrategy
extends Cloneable

Implementations are strategies used by MqttClient implementation to reconnect to the broker if the connection is lost. Implementations must be thread safe.

Method Summary

ReconnectionStrategy	clone()
void	connectionEstablished() Called by an MqttClient instance when a connection to the broker is established.
long	connectionLost(MqttClient client, Throwable cause) Called by an MqttClient each time the connection to the broker is lost other than by an intentional disconnect.

Returns:

Milliseconds the client should wait before trying to connect to the broker again. If <= 0 the client will stop trying to connect to the broker.

connectionEstablished

void connectionEstablished()

Called by an MqttClient instance when a connection to the broker is established.

clone

ReconnectionStrategy clone()
