Method Detail

getName

public String getName()

Specified by:

getName in interface Cube

Specified by:

getName in interface OlapElement

getUniqueName

public String getUniqueName()

Specified by:

getUniqueName in interface OlapElement

getQualifiedName

public String getQualifiedName()

Description copied from interface: OlapElement

Returns the name of this element qualified by its class, for example "hierarchy 'Customers'".

Specified by:

getQualifiedName in interface OlapElement

getDimension

public Dimension getDimension()

Description copied from interface: OlapElement

Returns the dimension of a this expression, or null if no dimension is defined. Applicable only to set expressions.

Example 1:

 [Sales].children
 

has dimension [Sales].

Example 2:

 order(except([Promotion Media].[Media Type].members,
              {[Promotion Media].[Media Type].[No Media]}),
       [Measures].[Unit Sales], DESC)
 

has dimension [Promotion Media].

Example 3:

 CrossJoin([Product].[Product Department].members,
           [Gender].members)
 

has no dimension (well, actually it is [Product] x [Gender], but we can't represent that, so we return null);

Specified by:

getDimension in interface OlapElement
