- Direct Known Subclasses:

public class UniqueNameFeatureTypeImpl
- extends FeatureTypeImpl
A specialisation of FeatureTypeImpl
that avoids equality tests on feature types with
cyclic definitions by considering features types to be equal if and only if their names are
equal.
Users of this class must not create multiple 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.
It should be noted that app-schema does not support the multiple definition XSD types with the
same name. This restriction allows multiple XSD elements and thus WFS feature types (with
different names) to have the same XSD type, because the XSD type can be recognised by name even
if it has a cyclic definition. This simplified equality testing allows FeatureTypeCache
to handle these types, despite their cyclic definition preventing a full recursive implementation
of equals(Object)
equals(). Unit test coverage is in GeoServer app-schema-test
DuplicateTypeTest.
