  • Method Details

    • connected

      void connected(ChannelCommunicationData channelData)
      Method that should be called when the connection to a node was established. This method should invoke the appropriate listeners added via addListener(IClusterChannelStateListener).
      Parameters:
      channelData - Details about the current state of the channel for the node.

    • disconnected

      void disconnected(ChannelCommunicationData channelData)
      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 addListener(IClusterChannelStateListener).
      Parameters:
      channelData - Details about the current state of the channel for the node.

    • closed

      void closed(ChannelCommunicationData channelData)
      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 addListener(IClusterChannelStateListener).
      Parameters:
      channelData - Details about the current state of the channel for the node.

    • addListener

      void addListener(IClusterChannelStateListener listener)
      Adds a listener that will be invoked when an event related to a change in a channel occurs.
      Parameters:
      listener - Listener to add that will be invoked when an event occurs.

    • removeListener

      void removeListener(IClusterChannelStateListener listener)
      Removes a listener previously added via addListener(IClusterChannelStateListener).
      Parameters:
      listener - Listener that should not be invoked anymore.
