        public final java.util.List dimensions
        List of dimensions that define this tile.

        Each dimension is a column from the lattice. The list of dimensions defines the level of aggregation, like a GROUP BY clause.

        Required, but may be empty. Each element is either a string (the unique label of the column within the lattice) or a string list (a pair consisting of a table alias and a column name).
