Method Detail

getArguments

public PricingEngine.Arguments getArguments()

Specified by:

getArguments in interface PricingEngine

getResults

public PricingEngine.Results getResults()

Specified by:

getResults in interface PricingEngine

reset

public void reset()

Specified by:

reset in interface PricingEngine

update

public void update()

Description copied from interface: Observer

This method is called whenever the observed object is changed.

Specified by:

update in interface PricingEngine

Specified by:

update in interface Observer

Overrides:

update in class FDEngineAdapter<FDAmericanCondition<FDDividendEngine>,VanillaOption.Engine>

addObserver

public void addObserver(Observer observer)

Description copied from interface: Observable

Attaches a observer to the Observable. After attachment the observer gets informed about changes in the Observable.

Specified by:

addObserver in interface Observable

Overrides:

Parameters:

observer - The observer to attach to the observable

countObservers

public int countObservers()

Description copied from interface: Observable

Counts how many Observers were attached to this class.

Specified by:

countObservers in interface Observable

Overrides:

countObservers in class FDEngineAdapter<FDAmericanCondition<FDDividendEngine>,VanillaOption.Engine>

Returns:

the number of Observers

Parameters:

observer - The observer to detach from the observable

deleteObservers

public void deleteObservers()

Description copied from interface: Observable

Detaches all previously attached observer to the observable. After detachment observers do not longer receive change notifications from the observable.

Specified by:

deleteObservers in interface Observable

Overrides:

deleteObservers in class FDEngineAdapter<FDAmericanCondition<FDDividendEngine>,VanillaOption.Engine>

getObservers

public java.util.List<Observer> getObservers()

Description copied from interface: Observable
