Interface ErrorListener

All Known Implementing Classes:

ConnectionManager

public interface ErrorListener

This interface is used to notify the application of errors that occur in an underlying messaging connection.

This should be set before the connection is initiated.

The connection error callback is called in 1 of the 3 scenarios

• The connection with the server is closed and an attempt will not be made to reconnect. In this case the exception will be of type ConnectionException. The status of the connection will be NOT_CONNECTED
• The connection with the server is lost but an attempt will be made to reconnect. In this scenario the exception will be of type TemporaryConnectionException. (This replaces the deprecated ReconnectException.) The status of the connection will be RECONNECTING.
• The connection with the server has been recovered. In this scenario the exception will be of type TemporaryConnectionException. (This replaces the deprecated ReconnectException.) The status of the connection will be CONNECTED.

Temporary connections serve to notify the application that the connection is down temporarily and recovery will be attempted. API Calls to sent and receive messages can continue as normal without being impacted. (Messages are typically queued by the underlying implementation until the connection is resumed.)
