static bool  getCentroid (const geom::Geometry &geom, geom::Coordinate ¢) 
Computes the centroid point of a geometry. More...  
Computes the centroid of a Geometry of any dimension.
If the geometry is nomimally of higher dimension, but contains only components having a lower effective dimension (i.e. zero length or area), the centroid will be computed appropriately.
If the input geometries are empty, a null
Coordinate is returned.
