Method Summary

boolean	equals(Object obj)
Cube	getCube() Returns the cube.
Dimension	getDimension() Returns the dimension of this type, or null if not known.
Hierarchy	getHierarchy() Returns the hierarchy of this type.
Level	getLevel() Returns the level of this type, or null if not known.
int	hashCode()
boolean	usesDimension(Dimension dimension, boolean maybe) Returns whether this type contains a given dimension. For example: DimensionType([Gender]) uses only the [Gender] dimension. TupleType(MemberType([Gender]), MemberType([Store])) uses [Gender] and [Store] dimensions. The maybe parameter comes into play when the dimensional information is incomplete.

Constructor Detail

CubeType

public CubeType(Cube cube)

Creates a type representing a cube.

Parameters:

cube - Cube

Method Detail

getCube

public Cube getCube()

Returns the cube.

Returns:

the cube

usesDimension

public boolean usesDimension(Dimension dimension,
                             boolean maybe)

Description copied from interface: Type

Returns whether this type contains a given dimension.

For example:

• DimensionType([Gender]) uses only the [Gender] dimension.
• TupleType(MemberType([Gender]), MemberType([Store])) uses [Gender] and [Store] dimensions.

The maybe parameter comes into play when the dimensional information is incomplete. For example, when applied to TupleType(MemberType(null), MemberType([Store])), usesDimension([Gender], false) returns true because it is possible that the expression returns a member of the [Gender] dimension.

Specified by:

usesDimension in interface Type

Parameters:

dimension - Dimension

maybe - If true, returns true only if this type definitely uses the dimension

Returns:

whether this type definitely (or if maybe is true, possibly) uses the given dimension
