Examples of TypeHierarchy

PrologPlusCG.prolog.TypeHierarchy
client.net.sf.saxon.ce.type.TypeHierarchy
This class exists to provide answers to questions about the type hierarchy. Because such questions are potentially expensive, it caches the answers. There is one instance of this class for a Configuration.
edu.cmu.cs.crystal.util.TypeHierarchy
net.sf.saxon.type.TypeHierarchy
This class exists to provide answers to questions about the type hierarchy. Because such questions are potentially expensive, it caches the answers. There is one instance of this class for a Configuration.

This class exists to provide answers to questions about the type hierarchy. Because such questions are potentially expensive, it caches the answers. There is one instance of this class for a Configuration.
org.xmlvm.util.analytics.data.TypeHierarchy
Holds the hierarchical dependencies between types, such as an inheritance hierarchy.
