- def isInRing(p: Coordinate, ring: Array[Coordinate]): Boolean
Tests whether a point lies inside or on a ring.
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.
- p
point to check for ring inclusion
- ring
an array of coordinates representing the ring (which must have first point identical to last point) return true if p is inside ring

- def isOnLine(p: Coordinate, line: CoordinateSequence): Boolean
Tests whether a point lies on the line defined by a {link CoordinateSequence}.
Tests whether a point lies on the line defined by a {link CoordinateSequence}.
- p
the point to test
- line
the line coordinates return true if the point is a vertex of the line or lies in the interior of a line segment in the line
- def isOnLine(p: Coordinate, line: Array[Coordinate]): Boolean
Tests whether a point lies on the line defined by a list of coordinates.
Tests whether a point lies on the line defined by a list of coordinates.
- p
the point to test
- line
the line coordinates return true if the point is a vertex of the line or lies in the interior of a line segment in the line
- def locateInRing(p: Coordinate, ring: Array[Coordinate]): Int
Determines whether a point lies in the interior, on the boundary, or in the exterior of a ring.
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.
- p
point to check for ring inclusion
- ring
an array of coordinates representing the ring (which must have first point identical to last point) return the { @link Location} of p relative to the ring
