void onBusBindingOpening(String busName)

Notifies that an AEP engine is opening a bus binding.

Parameters:

busName - The name of the bus bound to.

onBusBindingOpened

void onBusBindingOpened(String busName)

Notifies that an AEP engine's bus binding is open and operational.

Parameters:

busName - The name of the bus bound to.

onBusBindingFailed

void onBusBindingFailed(String busName,
                        String cause)

Notifies that an AEP engine's bus binding has failed.

Parameters:

busName - The name of the bus bound to.

cause - A string containing a description of the cause of failure.

onBusBindingDestroyed

void onBusBindingDestroyed(String busName)

Notifies that an AEP engine's bus binding has been destroyed (torn down).

Parameters:

busName - The name of the bus bound to.

Threading:

This method can be invoked concurrently by multiple threads with itself and other methods in this interface.

onChannelOpened

void onChannelOpened(String busName,
                     String channelName,
                     boolean joined)

Notifies that a bus channel has been opened.

Parameters:

busName - The name of the bus containing the channel.

channelName - The name of the channel.

joined - Indicates whether the channel was joined or not.

onChannelClosed

void onChannelClosed(String busName,
                     String channelName)

Parameters:

busName - The name of the bus containing the channel.

channelName - The name of the channel.

onClientConnected

void onClientConnected(String clientName)

Notifies that a 'server' client has connected.

Parameters:

clientName - The name of the connected client.
