Interface PlacemarkDescriptor

All Known Implementing Classes:

AbstractPlacemarkDescriptor, GcpDescriptor, GenericPlacemarkDescriptor, GeometryDescriptor, PinDescriptor, PointDescriptor, PointPlacemarkDescriptor, TrackPointDescriptor

public interface PlacemarkDescriptor

Placemark descriptors are used to describe and create Placemarks.

New placemark descriptors can be added by using the Service Provider Interface META-INF/services/PlacemarkDescriptor.

Since this interface is likely to change, clients should not directly implement it. Instead they should derive their implementation from AbstractPlacemarkDescriptor.

Since:

BEAM 2.0 (full revision since BEAM 4.10)

Version:

Method Details

createPlacemark

Placemark createPlacemark(org.opengis.feature.simple.SimpleFeature feature)

Creates a new placemark by wrapping the given feature.

Parameters:

feature - The feature to be wrapped.

Returns:

The new placemark.

setUserDataOf

void setUserDataOf(org.opengis.feature.simple.SimpleFeatureType compatibleFeatureType)

Asks the descriptor to set any application specific information in the feature type's user data. When called, the framework has already classified the given feature type as being DecodeQualification.INTENDED or DecodeQualification.SUITABLE by consulting the method getCompatibilityFor(org.opengis.feature.simple.SimpleFeatureType).

Implementors of this method may consider setting specific user data that allows getCompatibilityFor(org.opengis.feature.simple.SimpleFeatureType) to return DecodeQualification.INTENDED after e.g. data has been deserialized from a persistent data store.

Parameters:

compatibleFeatureType - A compatible feature type whose user data may or may not be altered.

getCompatibilityFor

DecodeQualification getCompatibilityFor(org.opengis.feature.simple.SimpleFeatureType featureType)

Gets the compatibility for the given featureType with respect to the placemarks created by this descriptor.

The method shall only return DecodeQualification.INTENDED, if the descriptor was designed for interpreting the given feature type, e.g. by inspecting the featureType's user data which may be set by setUserDataOf(org.opengis.feature.simple.SimpleFeatureType).

The method may return DecodeQualification.SUITABLE, if the createPlacemark(org.opengis.feature.simple.SimpleFeature) method can successfully create a new placemark from a feature having the compatible featureType.

Parameters:

featureType - The feature type to be tested.

Returns:

true, if the featureType is compatible.

getBaseFeatureType

org.opengis.feature.simple.SimpleFeatureType getBaseFeatureType()

Gets the feature type that provides the minimum set of attributes required for this placemark descriptor.

Returns:

The base feature type.
