Operations

Additionally, for each of the predicate and construction functor types listed above, there is 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 exists:

template<class OutputIterator >
OutputIterator copy_rectangle_vertices_2 (const Rectangle_2 &r, OutputIterator o) const
 copies the four vertices of r in counterclockwise order to o.
 
template<class OutputIterator >
OutputIterator copy_parallelogram_vertices_2 (const Parallelogram_2 &p, OutputIterator o) const
 copies the four vertices of p in counterclockwise order to o.
 
template<class OutputIterator >
OutputIterator copy_strip_lines_2 (const Strip_2 &s, OutputIterator o) const
 copies the two lines bounding s to o.
 
Construct_vector_2 construct_vector_2_object () const
 

Member Typedef Documentation

◆ Area_less_parallelogram_2

AdaptableBinaryFunction class op: Parallelogram_2 \( \times\) Parallelogram_2 \( \rightarrow\) bool.

op(p1,p2) returns true, iff the area of \( p1\) is strictly less than the area of \( p2\).

◆ Area_less_rectangle_2

AdaptableBinaryFunction class.

op: Rectangle_2 \( \times\) Rectangle_2 \( \rightarrow\) bool. op(r1,r2) returns true, iff the area of \( r1\) is strictly less than the area of \( r2\).

◆ Construct_parallelogram_2

Function class.

op: Point_2 \( \times\) Direction_2 \( \times\) Point_2 \( \times\) Direction_2 \( \times\) Point_2 \( \times\) Point_2 \( \rightarrow\) 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.

◆ Construct_rectangle_2

Function class op: Point_2 \( \times\) Direction_2 \( \times\) Point_2 \( \times\) Point_2 \( \times\) Point_2 \( \rightarrow\) 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.

◆ Construct_strip_2

Function class op: Point_2 \( \times\) Direction_2 \( \times\) Point_2 \( \rightarrow\) Strip_2.

op(p1,d,p2) returns the strip bounded by the lines through p1 resp. p2 with direction d.

◆ Construct_vector_from_direction_2

AdaptableFunctor.

op: Direction_2 \( \rightarrow\) Vector_2.

op(d) returns a vector in direction d.

◆ Width_less_strip_2

AdaptableBinaryFunction class.

op: Strip_2 \( \times\) Strip_2 \( \rightarrow\) bool. op(s1,s2) returns true, iff the width of \( s1\) is strictly less than the width of \( s2\).
