|
* Computes the location of points |

|
|
|
|
|
|
|
* relative to an areal {@link Geometry}, |
37
|
|
|
|
|

|
|
|
|
|
|
* This algorithm is suitable for use in cases where |
40

|
|
|

|
* only one or a few points will be tested against a given area. |
41
|
|

|
|
|
|
|
|
* The algorithm used is only guaranteed to return correct results |
43
|
|
|
|
|
|
|
* for points which are not on the boundary of the Geometry. |
