MdmValueHierarchy (Oracle OLAP Java API Reference)

An MdmHierarchy that represents members of an Oracle OLAP dimension that are organized hierarchically by values rather than by levels. An application creates an MdmValueHierarchy with the findOrCreateValueHierarchy method of an MdmPrimaryDimension.

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.

To map an MdmValueHierarchy to a data source, you use a SolvedValueHierarchyMap. You specify the children of the hierarchy with the setKeyExpression method of the SolvedValueHierarchyMap and you specify the parents with the setParentKeyExpression method.

Method Summary
`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.
`SolvedValueHierarchyMap`	`findOrCreateSolvedValueHierarchyMap()` Gets the `SolvedValueHierarchyMap` that is contained by this `MdmValueHierarchy` or creates a new `SolvedValueHierarchyMap` if one does not already exist.
`MdmDimensionMemberInfo`	`getDefaultMember()` Gets the `MdmDimensionMemberInfo` that specifies the default member of this `MdmValueHierarchy`.
`SolvedValueHierarchyMap`	`getSolvedHierarchyMap()` Gets the `SolvedValueHierarchyMap` that is contained by this `MdmValueHierarchy`.
`void`	`setDefaultMember(MdmDimensionMemberInfo defaultMember)` Specifies a default member for this `MdmValueHierarchy`.
`void`	`setSolvedHierarchyMap(SolvedValueHierarchyMap map)` Specifies a `SolvedValueHierarchyMap` for this `MdmValueHierarchy`.

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.

Specified by:: acceptVisitor in class MdmObject

Parameters:: visitor - An MdmObjectVisitor.; context - An Object.
Returns:: The Object returned by the visitMdmValueHierarchy method.

getDefaultMember

public MdmDimensionMemberInfo getDefaultMember()
                                        throws oracle.express.mdm.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.

Specified by:: getDefaultMember in class MdmHierarchy

Returns:: An MdmDimensionMemberInfo that has the default member of this MdmValueHierarchy.
Throws:: oracle.express.mdm.MetadataNotFoundException

setDefaultMember

public void setDefaultMember(MdmDimensionMemberInfo defaultMember)
                      throws oracle.express.mdm.MetadataNotFoundException,
                             MdmInvalidValueException

Specifies a default member for this MdmValueHierarchy.

Specified by:: setDefaultMember in class MdmHierarchy

Parameters:: defaultMember - An MdmDimensionMemberInfo that has the value that you want the default member of this MdmValueHierarchy to have.
Throws:: oracle.express.mdm.MetadataNotFoundException; MdmInvalidValueException

getSolvedHierarchyMap

public final SolvedValueHierarchyMap getSolvedHierarchyMap()

Gets the SolvedValueHierarchyMap that is contained by this MdmValueHierarchy.

Returns:: The SolvedValueHierarchyMap for this MdmValueHierarchy.

setSolvedHierarchyMap

public final void setSolvedHierarchyMap(SolvedValueHierarchyMap map)

Specifies a SolvedValueHierarchyMap for this MdmValueHierarchy.

Parameters:: map - The SolvedValueHierarchyMap for this MdmValueHierarchy.

findOrCreateSolvedValueHierarchyMap

public SolvedValueHierarchyMap findOrCreateSolvedValueHierarchyMap()

Gets the SolvedValueHierarchyMap that is contained by this MdmValueHierarchy or creates a new SolvedValueHierarchyMap if one does not already exist.
