public final class MdmValueHierarchy

extends MdmHierarchy

An MdmHierarchy that represents elements of an Oracle OLAP dimension that are organized hierarchically by values rather than by levels. The hierarchical organization is defined by parent-child relationships between the elements of the MdmValueHierarchy. For example, the employee reporting structure of a company can be represented with parent-child relationships but without levels.

MdmAttribute objects record the parent-child relationships among the elements of an MdmValueHierarchy You use the getParentAttribute and getAncestorsAttribute methods to get the MdmAttribute objects that relate parents to children and ancestors to descendents, respectively.

A database administrator can specify an MdmHierarchy as an MdmValueHierarchy in the OLAP Catalog. You can also create a transient MdmValueHierarchy with the createValueHierarchy method of an MdmCustomObjectFactory.

acceptVisitor

public java.lang.Object acceptVisitor(MdmObjectVisitor visitor,
                                      java.lang.Object context)

Parameters:

visitor - An MdmObjectVisitor.

context - An Object.

Returns:

The Object returned by the visitMdmValueHierarchy method.

Overrides:

acceptVisitor in class MdmObject
