Constructor Detail

RolapCubeLevel

public RolapCubeLevel(RolapLevel level,
                      RolapCubeHierarchy cubeHierarchy)

Method Detail

setStarKeyColumn

public void setStarKeyColumn(RolapStar.Column column)

getStarKeyColumn

public RolapStar.Column getStarKeyColumn()

This is the RolapStar.Column that is related to this RolapCubeLevel

Returns:

the RolapStar.Column related to this RolapCubeLevel

getBaseStarKeyColumn

public RolapStar.Column getBaseStarKeyColumn(RolapCube baseCube)

this method returns the RolapStar.Column if non-virtual, if virtual, find the base cube level and return it's column

Parameters:

baseCube - the base cube for the specificed virtual level

Returns:

the RolapStar.Column related to this RolapCubeLevel

getCube

public final RolapCube getCube()

Returns the (non virtual) cube this level belongs to.

Returns:

cube

getDimension

public final RolapCubeDimension 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);
