Field Detail

disableCurrentConvergence

protected boolean disableCurrentConvergence

The next flag indicates if the current convegence should be neglected. This is used in situations where convergence was reached, but the network continues running. If we would not neglect the current convergence event would continue to be generated. This flag is used to disable the event sfor the current convergence.

Constructor Detail

ConvergenceObserver

public ConvergenceObserver()

Creates a new instance of ConvergenceObserver

Method Detail

addConvergenceListener

public void addConvergenceListener(ConvergenceListener aListener)

Adds a convergence listener.

Parameters:

aListener - the listener to add.

removeConvergenceListener

public void removeConvergenceListener(ConvergenceListener aListener)

Removes a convergence listener.

Parameters:

aListener - the listener to remove.

fireNetConverged

protected void fireNetConverged(Monitor aMonitor)

Fires a net converged event.

Parameters:

aMonitor - a monitor object.

disableCurrentConvergence

public void disableCurrentConvergence()

Disables current convergence events. Used in situations where convergence was reached but the network keeps running. By calling this method no events signaling convergence was reached will be greated. Whenever the network moves out of the convergence state, new events will be created again once the system reaches convergence.
