Member Typedef Documentation

◆ Angle_less

AdaptableBinaryFunction class: Point_2 \( \times\) Point_2 \( \rightarrow\) bool.

It returns true, iff the angle of the direction corresponding to the first argument with respect to the positive \( x\)-axis is less than the angle of the direction corresponding to the second argument.

◆ Max_coordinate

AdaptableUnaryFunction class: Point_2 \( \rightarrow\) FT.

Max_coordinate(p) returns the coordinate of p with largest absolute value.

◆ Scale

AdaptableBinaryFunction class: Point_2 \( \times\) FT \( \rightarrow\) Point_2.

Scale(p,k) returns the point that results from scaling the vector corresponding to p by a factor of k.

◆ Sum

AdaptableBinaryFunction class: Point_2 \( \times\) Point_2 \( \rightarrow\) Point_2.

It returns the point that results from adding the vectors corresponding to both arguments.
