class ReaderMonitor(Observable):

View In Hierarchy

Class that monitors reader insertion/removal. and notify observers

note: a reader monitoring thread will be running as long as the reader monitor has observers, or ReaderMonitor.stop() is called.

It implements the shared state design pattern, where objects of the same type all share the same state, in our case essentially the ReaderMonitoring Thread. Thanks to Frank Aune for implementing the shared state pattern logics.

Method countObservers Undocumented
Method deleteObservers Undocumented
Method hasChanged Undocumented
Method notifyObservers If 'changed' indicates that this object has changed, notify all its observers, then call clearChanged(). Each observer has its update() called with two arguments: this observable object and the generic 'arg'.
Method setChanged Undocumented
Instance Variable changed Undocumented
Instance Variable obs Undocumented
