getCompatibilityFor

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

Description copied from interface: PlacemarkDescriptor

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 PlacemarkDescriptor.setUserDataOf(org.opengis.feature.simple.SimpleFeatureType).

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

Specified by:

getCompatibilityFor in interface PlacemarkDescriptor

Overrides:

getCompatibilityFor in class AbstractPlacemarkDescriptor

Parameters:

featureType - The feature type to be tested.

Returns:

true, if the featureType is compatible.

setUserDataOf

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

Description copied from interface: PlacemarkDescriptor

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 PlacemarkDescriptor.getCompatibilityFor(org.opengis.feature.simple.SimpleFeatureType).

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

Specified by:

setUserDataOf in interface PlacemarkDescriptor

Overrides:

setUserDataOf in class AbstractPlacemarkDescriptor

Parameters:

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

getRoleName

public String getRoleName()

getRoleLabel

public String getRoleLabel()
