Called when the control task is connected/disconnected or unstable

Specified by:

controlTaskStateChanged in interface TaskGraphListener

nodeAdded

public void nodeAdded(TaskNodeEvent event)

Called when a data input node is added.

Specified by:

nodeAdded in interface TaskListener

nodeRemoved

public void nodeRemoved(TaskNodeEvent event)

Called when a data input node is removed.
