execute

public abstract boolean execute(Geometry inputGeom1,
 Geometry inputGeom2,
 SpatialReference sr,
 String de_9im_string,
 ProgressTracker progressTracker)

Performs the Relation operation between two geometries using the DE-9IM matrix encoded as a string.

Parameters:

inputGeom1 - The first geometry in the relation.

inputGeom2 - The second geometry in the relation.

sr - The spatial reference of the geometries.

de_9im_string - The DE-9IM matrix relation encoded as a string.

Returns:

Returns True if the relation holds, False otherwise.

local

public static OperatorRelate local()

canAccelerateGeometry

public boolean canAccelerateGeometry(Geometry geometry)

Description copied from class: Operator

Returns true if the geometry can be accelerated.

Overrides:

canAccelerateGeometry in class Operator

Parameters:

geometry -

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.
