Tests whether a point lies inside or on a ring.
The ring may be oriented in either direction. A point lying exactly on the ring boundary is considered to be inside the ring.
This method does not first check the point against the envelope of the ring.
- Parameters
-
p | point to check for ring inclusion |
ring | an array of coordinates representing the ring (which must have first point identical to last point) |
- Returns
true
if p is inside ring

- RayCrossingCounter::locatePointInRing()
Tests whether a point lies on the line defined by a CoordinateSequence.
- Parameters
-
p | the point to test |
line | the line coordinates |
- Returns
- true if the point is a vertex of the line or lies in the interior of a line segment in the line
Determines whether a point lies in the interior, on the boundary, or in the exterior of a ring. The ring may be oriented in either direction.
This method does not first check the point against the envelope of the ring.
- Parameters
-
p | point to check for ring inclusion |
ring | an array of coordinates representing the ring (which must have first point identical to last point) |
- Returns
- the Location of p relative to the ring
