public abstract class SolvedHierarchyMap

extends DimensionMap

An abstract extension of DimensionMap that represents the mapping to data sources of an MdmHierarchy that is solved. A solved hierarchy is one for which the aggregate data exists in persistent storage for the MdmMeasure objects that are dimensioned by the members of the hierarchy.

A SolvedHierarchyMap must have an associated AttributeMap for the parent MdmAttribute of the hierarchy. It must also identify the level depth of each member.

If the SolvedHierarchyMap is for an MdmLevelHierarchy, then it can identify the level depth in either of the following ways.

• Have an AttributeMap for the level depth MdmAttribute.
• Have an AttributeMap for the level name MdmAttribute.

If the SolvedHierarchyMap is for an MdmValueHierarchy, then it can identify the level depth by having an AttributeMap for the level depth MdmAttribute.

A SolvedHierarchyMap for either subclass of MdmHierarchy can also identify the level depth by having an GID Expression. However, this method does not scale well, so an application should use the level depth or level name method.

Method Summary

Expression	getParentLevelIDExpression() Gets the column that contains the identifiers for the parents of the members of the levels of the hierarchy.
void	setLevelIDExpression(Expression input) Specifies the column that contains the identifiers for the levels of the hierarchy.
void	setParentKeyExpression(Expression input) Specifies the column of the relational table that identifies the parents of the members of the hierarchy.
void	setParentLevelIDExpression(Expression input) Specifies the column that contains the identifiers for the parents of the members of the levels of the hierarchy.
