quadrature_option_type (2rheolef)

The quadrature_option_type class is used to send options to the integrate function see integrate(4). This class allows to set the family (Gauss, Gauss-Lobatto, etc) and the polynomial degree that is exactly integrated. See also the see quadrature(2) for more on quadrature formulae.
