public final class MdmValueHierarchy

extends MdmHierarchy

An MdmHierarchy that represents members 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 members 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 members 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 Oracle OLAP metadata. You can also create a transient MdmValueHierarchy with the createValueHierarchy method of an MdmCustomObjectFactory.

Method Detail

acceptVisitor

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

Calls the visitMdmValueHierarchy method on the specified MdmObjectVisitor and passes that method this MdmValueHierarchy and the specified context object.

Overrides:

acceptVisitor in class MdmObject

Parameters:

visitor - An MdmObjectVisitor.

context - An Object.

Returns:

The Object returned by the visitMdmValueHierarchy method.

getValueHierarchyMap

public MtmValueHierarchyMap getValueHierarchyMap()
                                          throws MetadataNotFoundException

Gets the MtmValueHierarchyMap for this MdmValueHierarchy. The MtmValueHierarchyMap maps the members of this MdmValueHierarchy to data in the Oracle Database.

Returns:

The MtmValueHierarchyMap for this MdmValueHierarchy.

getDefaultMember

public MdmDimensionMemberInfo getDefaultMember()
                                        throws MetadataNotFoundException

Gets the MdmDimensionMemberInfo that specifies the default member of this MdmValueHierarchy. From the MdmDimensionMemberInfo you can get the value of the default member by calling its getLocalValue or getUniqueValue method.

Overrides:

getDefaultMember in class MdmHierarchy

Returns:

An MdmDimensionMemberInfo that has the default member of this MdmValueHierarchy.

setDefaultMember

public void setDefaultMember(MdmDimensionMemberInfo defaultMember)
                      throws MetadataNotFoundException,
                             MdmInvalidValueException

Specifies a default member for this MdmValueHierarchy.

Overrides:

setDefaultMember in class MdmHierarchy

Parameters:

defaultMember - An MdmDimensionMemberInfo that has the value that you want the default member of this MdmValueHierarchy to have.
