getHelper

public FeaturePagingHelper getHelper()

Returns a reference to the Paging Helper used to load the data from the DataStore.

Returns:

the paging pagingHelper

setFeatureType

public void setFeatureType(FeatureType featureType)

Sets the FeatureType to show in the table. Used for FeatureStores with many simultaneous FeatureTypes supported. Will cause a reload of the current data.

Parameters:

featureType - the FeatureType of the Features

setSelectionUp

public void setSelectionUp(boolean selectionUp)

fireTableChanged

protected void fireTableChanged()

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.
