Method Detail

execute

public abstract boolean execute(Geometry inputGeom1,
              Geometry inputGeom2,
              SpatialReference sr,
              ProgressTracker progressTracker)

Performs the given relation operation between two geometries.

Returns:

Returns True if the relation holds, False otherwise.

canAccelerateGeometry

public boolean canAccelerateGeometry(Geometry geometry)

Description copied from class: Operator

Returns true if the geometry can be accelerated.

Overrides:

canAccelerateGeometry in class Operator

Returns:

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

accelerateGeometry

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

Description copied from class: Operator

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 the same accelerator, some require a different one. If the accelerator is built for the given parameters, the method returns immediately.

Overrides:

accelerateGeometry in class Operator

Parameters:

geometry - The geometry to be accelerated

spatialReference - The spatial reference of that geometry

accelDegree - The acceleration degree for geometry.
