示例1:
bool
BufferResultMatcher::isBufferResultMatch(const geom::Geometry& actualBuffer,
const geom::Geometry& expectedBuffer,
double distance)
{
if (actualBuffer.isEmpty() && expectedBuffer.isEmpty())
return true;
/**
* MD - need some more checks here - symDiffArea won't catch
* very small holes ("tears")
* near the edge of computed buffers (which can happen
* in current version of JTS (1.8)).
* This can probably be handled by testing
* that every point of the actual buffer is at least a certain
* distance away from the geometry boundary.
*/

std::cerr << "isSymDiffAreaInTolerance failed" << std::endl;

}示例2: failed
bool

double distance)

// NOTE: we need to test hausdorff distance in both directions
