org.apache.derby.iapi.sql.dictionary
Class SubConstraintDescriptor  

java.lang.Object
  org.apache.derby.iapi.sql.dictionary.TupleDescriptor
      org.apache.derby.iapi.sql.dictionary.SubConstraintDescriptor

All Implemented Interfaces:

UniqueTupleDescriptor

Direct Known Subclasses:

SubCheckConstraintDescriptor, SubKeyConstraintDescriptor

---

public abstract class SubConstraintDescriptor

extends TupleDescriptor

implements UniqueTupleDescriptor

This interface is used to get information from a SubConstraintDescriptor. A SubKeyConstraintDescriptor is used within the DataDictionary to get auxiliary constraint information from the system table that is auxiliary to sysconstraints.
