public class MDHierarchy

extends MDFolder

A client-side representation of a hierarchy in an analytic workspace. An MDHierarchy provides, to a java client, information about a hierarchy in the workspace.

An OLAP hierarchy is a logical structure that uses levels to organize data. A hierarchy can be used to define data aggregation: for example, in a Time dimension, a hierarchy might be used to aggregate data from the "Month" level to the "Quarter" level to the "Year" level. A hierarchy can also be used to define a navigational drill path, regardless of whether the levels in the hierarchy represent aggregated totals.

As an MDFolder, an MDHierarchy can contain other MDObjects. MDHierarchy objects can contain MDLevels.

Method Detail

getDimension

public MDDimension getDimension()
                         throws MetadataManagerException

Retrieves the dimension for this hierarchy.

Returns:

The dimension that this hierarchy structures.

Throws:

MetadataManagerException - If the connection fails during the execution of this method or if there is a problem retrieving objects from the server.

getLevels

public MDLevel[] getLevels()
                    throws MetadataManagerException

Retrieves the levels in this hierarchy.

Returns:

The levels of this hierarchy.

Throws:

MetadataManagerException - If the connection fails during the execution of this method or if there is a problem retrieving objects from the server.

getDataType

public java.lang.String getDataType()

Retrieves the data type of this hierarchy.

Returns:

A constant that represents the datatype. Valid constants are listed in the See Also section.
