Polygon LINQ

This project was created to imagine what an api for working with Polygons similar to LINQ would look like.

code examples

create Polygon

Polygon _polygon = new();
_polygon.Points.Add(new Point(0, 0));
_polygon.Points.Add(new Point(2, 0));
_polygon.Points.Add(new Point(2, 1));
_polygon.Points.Add(new Point(0, 1));

checking a polygon for a rectangle

(bool)_polygon.CheckIfThis.
    IsCornerCount(4).
    IsAllCornersIs(x => x == 90)

checking a polygon for a square

(bool)_polygon.CheckIfThis.
    IsCornerCount(4).
    IsAllCornersIs(x => x == 90).
    IsAllSidesIs((l, i, x) => l[i-1] == x, 1)

function

// checking the number of corners
IsCornerCount(int count)

// checking the number of sides
IsSidesCount(int count)

// checking the two sides for parallelism
IsTwoSidesParallel(int n1, int n2)

// checking the function for all sides
IsAllSidesIs(Func<double[], int, double, bool> func, int startIndex = 0, int endIndex = -1)
IsAllSidesIs(Func<double, bool> func, int startIndex = 0, int endIndex = -1)

// checking the function for all corner
IsAllCornersIs(Func<double[], int, double, bool> func, int startIndex = 0, int endIndex = -1)
IsAllCornersIs(Func<double, bool> func, int startIndex = 0, int endIndex = -1)
