public ClusterChannelStateObserver()

Method Details

connected

public void connected(ChannelCommunicationData channelData)

Description copied from interface: IClusterChannelStateObserver

Method that should be called when the connection to a node was established. This method should invoke the appropriate listeners added via IClusterChannelStateObserver.addListener(IClusterChannelStateListener).

Specified by:

connected in interface IClusterChannelStateObserver

Parameters:

channelData - Details about the current state of the channel for the node.

disconnected

public void disconnected(ChannelCommunicationData channelData)

Description copied from interface: IClusterChannelStateObserver

Method that should be called when the connection to a node was cut. As long as the channel is not closed, the connection could be established later again. This method should invoke the appropriate listeners added via IClusterChannelStateObserver.addListener(IClusterChannelStateListener).

Specified by:

disconnected in interface IClusterChannelStateObserver

Parameters:

channelData - Details about the current state of the channel for the node.

closed

public void closed(ChannelCommunicationData channelData)

Description copied from interface: IClusterChannelStateObserver

Method that should be called when the channel was closed. Once the channel is closed, no more connections can be established anymore. This method should invoke the appropriate listeners added via IClusterChannelStateObserver.addListener(IClusterChannelStateListener).

Specified by:

closed in interface IClusterChannelStateObserver

Parameters:

channelData - Details about the current state of the channel for the node.

addListener

public void addListener(IClusterChannelStateListener listener)

Description copied from interface: IClusterChannelStateObserver

Adds a listener that will be invoked when an event related to a change in a channel occurs.

Specified by:

addListener in interface IClusterChannelStateObserver

Parameters:

listener - Listener to add that will be invoked when an event occurs.

removeListener

public void removeListener(IClusterChannelStateListener listener)

Description copied from interface: IClusterChannelStateObserver

Removes a listener previously added via IClusterChannelStateObserver.addListener(IClusterChannelStateListener).

Specified by:

removeListener in interface IClusterChannelStateObserver

Parameters:

listener - Listener that should not be invoked anymore.
