Description copied from interface: InfoByPoint

Executes a consultation about information of a point on the layer.

There is an area around the point where will got the information.

Specified by:

getInfo in interface InfoByPoint

Parameters:

p - point where is the consultation

tolerance - permissible margin around the coordinates of the point where the method will got the information. Each singular implementation of this method would use it in a different way. The coordinates also depend on the implementation.

cancel - shared object that determines if this layer can continue being drawn

Returns:

a DynObjectSet. If the InfoByPoint Object is a vector layer it should return a FeatureSet.

Throws:

LoadLayerException - any exception produced using the driver.

DataException - TODO

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.
