public final class MdmDerivedAttribute

extends MdmSingleValuedAttribute

An MdmSingleValuedAttribute that has values that Oracle OLAP derives from the Expression that is associated with the MdmDerivedAttribute. Oracle OLAP automatically generates some derived attributes, such as the parent attribute for an MdmHierarchy and the level depth attribute for an MdmLevelHierarchy. You can find an existing MdmDerivedAttribute or create a new one by using the findOrCreateDerivedAttribute of an MdmPrimaryDimension.

Method Summary
