 const std::vector< Real > & get_weights() const
The libMesh namespace provides an interface to certain functionality in the library. 
std::vector< Point > _points
The locations of the quadrature points in reference element space. 
std::vector< Real > _weights
The quadrature weights. 
Order _order
The polynomial order which the quadrature rule is capable of integrating exactly. ...
const std::vector< Point > & get_points() const
This class implements specific orders of Gauss quadrature. 
virtual void init(const Elem &e, unsigned int p_level=invalid_uint)
Initializes the data structures for a quadrature rule for the element e. 
virtual void init_1D() override
Uses a Gauss rule in 1D.
