ConnectionStateListener (AMPS Java Client (5.3.4.0.14fbce6f.256885))

All Known Implementing Classes:

MessageStream
```
public interface ConnectionStateListener
```
An interface that allows an application to be notified when the client state changes. To use a ConnectionStateListener, you implement this interface, construct an instance of your new class, and then use the addConnectionStateListener method on the Client to register for notifications. See the 'Java Developer Guide' for more details on monitoring connection state.

- Method Detail
  - connectionStateChanged
```
void connectionStateChanged(int newState_)
```
    Called on an implementation of this interface when the connection state changes. This method will be called immediately after the client detects the new state: in particular, this means that when the method is called with a state of 2, the client is connected, but has not yet logged on or completed any recovery (such as replaying the publish store, re-entered subscriptions, and so on). The listener should not issue commands on the client while recovery is in progress. Once recovery is complete, if you need to issue a command on this client, it must be executed on another thread. Executing a command within this method will deadlock the client.
    
    Parameters:
    
    newState_ - The connection state change.
