Examples of org.geotools.feature.type.UniqueNameFeatureTypeFactoryImpl

org.geotools.feature.type.UniqueNameFeatureTypeFactoryImpl
A specialisation of {@link FeatureTypeFactoryImpl} that returns {@link UniqueNameFeatureTypeImpl}instead of {@link FeatureTypeImpl} to avoid equality tests on types with cyclic definitions.
Users of this factory must not use it to create multiple FeatureType instances with the same name unless they represent the same type, because other parts of the implementation will assume they are equal, and if they are not, Bad Things Will Happen. @author Ben Caradoc-Davies (CSIRO Earth Science and Resource Engineering) @see GEOT-3354 @source $URL$
