accelerateGeometry

public boolean accelerateGeometry(Geometry geometry,
                                  SpatialReference spatialReference,
                                  Geometry.GeometryAccelerationDegree accelDegree)

Processes Geometry to accelerate operations on it. The Geometry and it's copies remain accelerated until modified. The acceleration of Geometry can be a time consuming operation. The accelerated geometry also takes more memory. Some operators share same the same accelerator, some require a different one. If the accelerator is built for the given parameters, the method returns immediately.

Parameters:

geometry - The geometry to be accelerated

spatialReference - The spatial reference of that geometry

accelDegree -

canAccelerateGeometry

public boolean canAccelerateGeometry(Geometry geometry)

Returns true if the geometry can be accelerated.

Parameters:

geometry -

Returns:

true for geometries that can be accelerated, false for geometries that cannot

deaccelerateGeometry

public static void deaccelerateGeometry(Geometry geometry)
