Class ObjectRelationalDataTypeDescriptor

java.lang.Object
  org.eclipse.persistence.descriptors.ClassDescriptor
      org.eclipse.persistence.descriptors.RelationalDescriptor
          org.eclipse.persistence.mappings.structures.ObjectRelationalDataTypeDescriptor

All Implemented Interfaces:

Serializable, Cloneable

public class ObjectRelationalDataTypeDescriptor
extends RelationalDescriptor

Purpose: Differentiates object-relational descriptors from normal relational descriptors. The object-relational descriptor describes a type not a table, (although there is normally a table associated with the type, unless it is aggregate).
