Member Function Documentation

do_order()

virtual int do_order ( ) const

protectedpure virtual

Derived classes shall return the order (>= 1) of this rule.

do_quadrature_points()

virtual const std::vector< Vector2< double > > & do_quadrature_points ( ) const

protectedpure virtual

Derived classes shall return the vector of quadrature points.

Each of these Vector2 objects represents the barycentric coordinates of a triangle (the third barycentric coordinate is implicit: it is the difference between unity and the sum of the other two coordinates).

do_weights()

virtual const std::vector< double > & do_weights ( ) const

protectedpure virtual

Derived classes shall return the vector of weights.

The sum of all weights must equal 1.0.

operator=() [1/2]

TriangleQuadratureRule & operator= ( const TriangleQuadratureRule & )

operator=() [2/2]

TriangleQuadratureRule & operator= ( TriangleQuadratureRule && )

order()

int order

(

)

const

Returns the order of this rule.

quadrature_points()

const std::vector< Vector2< double > > & quadrature_points

(

)

const

Returns the vector of quadrature points.

These are returned as the first two barycentric coordinates b0 b1; the third is just b2 = 1 - b0 - b1. Each of these has a corresponding weight returned by weights().

weights()

const std::vector< double > & weights

(

)

const

Returns the vector of weights.

These sum to 1 and there is one weight for each point returned by quadrature_points().
