方法的具体详情如下:
包路径:org.locationtech.jts.geom.Geometry
类名称:Geometry
方法名:getInteriorPoint
[英]Computes an interior point of this Geometry
. An interior point is guaranteed to lie in the interior of the Geometry, if it possible to calculate such a point exactly. Otherwise, the point may lie on the boundary of the geometry.
The interior point of an empty geometry is POINT EMPTY
.
[中]计算此Geometry
的内部点。如果可以精确计算内点,则保证内点位于几何体的内部。否则,该点可能位于几何体的边界上。
空几何体的内部点为POINT EMPTY
。
