Method Detail

constrainRequest

public boolean constrainRequest(RolapCubeMember member,
                                RolapCube baseCube,
                                CellRequest request)

Description copied from interface: RolapCubeLevel.LevelReader

Adds constraints to a cell request for a member of this level.

Specified by:

constrainRequest in interface RolapCubeLevel.LevelReader

Parameters:

member - Member to be constrained

baseCube - base cube if virtual level

request - Request to be constrained

Returns:

true if request is unsatisfiable (e.g. if the member is the null member)

                            RolapCube baseCube,
                            RolapCacheRegion cacheRegion)

Description copied from interface: RolapCubeLevel.LevelReader

Adds constraints to a cache region for a member of this level.

Specified by:

constrainRegion in interface RolapCubeLevel.LevelReader

Parameters:

predicate - Predicate

baseCube - base cube if virtual level

cacheRegion - Cache region to be constrained
