Owning value type for quadrature rules on canonical reference cells.
Construction requires:
- a supported cell family and non-negative polynomial exactness;
- a vector of points, with at least one element;
- for all points, coordinates must be finite;
- for all points, coordinates beyond the reference dimension of the cell family must be equal to zero; and
- a vector of finite weights, with as many elements as the points.
The constructor checks each requirement and throws InvalidArgumentException when one is violated.
Points may be duplicate or outside the reference cell, and weights may be zero or negative. Construction does not verify weight normalization or polynomial exactness.
