    • Method Detail

      • usesDimension

        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. 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.

        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
      • getDimension

        Dimension getDimension()
        Returns the dimension of this type, or null if not known.
        Returns:

      • getHierarchy

        Hierarchy getHierarchy()
        Returns the hierarchy of this type. If not applicable, throws.
        Returns:
        hierarchy of this type
      • getLevel

        Level getLevel()
        Returns the level of this type, or null if not known.
        Returns:
        level of this type
