Method Detail

getStatistics

public Statistics getStatistics(SimpleTaskStatus status)

Description copied from interface: StatisticsCapable

Gets the statistics of the object than implements this interface

Specified by:

getStatistics in interface StatisticsCapable

Returns:

the statistics

iterator

public java.util.Iterator<Band> iterator()

Specified by:

iterator in interface java.lang.Iterable<Band>

update

public void update(Observable observable,
                   java.lang.Object notification)

Description copied from interface: Observer

Called whenever a Observable object is changed and this Observer has registered on it to receive notifications.

Implementations of this method will be called for each simple notification or, if a complex notification is created, for each of the child notifications.

In the latter case, don't assume any ordering in the notification between this Observer and other Observers listening to the same Observable.

In a complex notification scenario, if you want to receive only the complex notification and not each of the child notifications, just implement the ComplexObserver and prepare this method implementation to handle receiving DefaultComplexNotification instances as well as direct notification objects.

Specified by:

update in interface Observer

Parameters:

observable - the observable object.

notification - the notification data.
