The following type is used for expensive precondition checking only.

Constructions

MinQuadrilateralTraits_2::Construct_vector_2
	a model for Kernel::Construct_vector_2.
MinQuadrilateralTraits_2::Construct_vector_from_direction_2
	AdaptableFunctor op: Direction_2 $$ Vector_2. op(d) returns a vector in direction d.

	a model for Kernel::Construct_opposite_direction_2.
MinQuadrilateralTraits_2::Construct_line_2
	a model for Kernel::Construct_line_2.
MinQuadrilateralTraits_2::Construct_rectangle_2
	Function class op: Point_2 $$ × Direction_2 $$ × Point_2 $$ × Point_2 $$ × Point_2 $$ Rectangle_2. If the points p1,p2,p3,p4 form the boundary of a convex polygon (oriented counterclockwise), op(p1,d,p2,p3,p4) returns the rectangle with one of the points on each side and one sides parallel to d.
MinQuadrilateralTraits_2::Construct_parallelogram_2
	Function class op: Point_2 $$ × Direction_2 $$ × Point_2 $$ × Direction_2 $$ × Point_2 $$ × Point_2 $$ Rectangle_2. If the points p1,p2,p3,p4 form the boundary of a convex polygon (oriented counterclockwise), op(p1,d1,p2,d2,p3,p4) returns the parallelogram with one of the points on each side and one side parallel to each of d1 and d2.
MinQuadrilateralTraits_2::Construct_strip_2
	Function class op: Point_2 $$ × Direction_2 $$ × Point_2 $$ Strip_2. op(p1,d,p2) returns the strip bounded by the lines through p1 resp. p2 with direction d.

Operations

Additionally, for each of the predicate and construction functor types listed above, there must exist a member function that requires no arguments and returns an instance of that functor type. The name of the member function is the uncapitalized name of the type returned with the suffix _object appended. For example, for the functor type Construct_vector_2 the following member function must exist:
