Class FeaturePropertyAccessorFactory
Object
FeaturePropertyAccessorFactory
- All Implemented Interfaces:
- PropertyAccessorFactory
public class FeaturePropertyAccessorFactory
- extends Object
- implements PropertyAccessorFactory
Creates a namespace aware property accessor for ISO Features.
The created accessor handles a small subset of xpath expressions, a non-nested "name" which
corresponds to a feature attribute, and "@id", corresponding to the feature id.
THe property accessor may be run against org.geotools.feature.Feature
, or against
org.geotools.feature.FeatureType
. In the former case the feature property value is
returned, in the latter a descriptor is returned (in case of "@" attributes, a Name is returned
or null if the attribute doesn't exist - can be used to validate an x-path!) .
