execute

public abstract GeometryCursor execute(GeometryCursor inputGeometries,
                                       GeometryCursor subtractor,
                                       SpatialReference sr,
                                       ProgressTracker progressTracker)

Performs the Topological Difference operation on the geometry set.

Parameters:

inputGeometries - is the set of Geometry instances to be subtracted by the subtractor

subtractor - is the Geometry being subtracted.

Returns:

Returns the result of the subtraction. The operator subtracts subtractor from every geometry in inputGeometries.

execute

public abstract Geometry execute(Geometry inputGeometry,
                                 Geometry subtractor,
                                 SpatialReference sr,
                                 ProgressTracker progressTracker)

Performs the Topological Difference operation on the two geometries.

Specified by:

execute in interface CombineOperator

Parameters:

inputGeometry - is the Geometry instance on the left hand side of the subtraction.

subtractor - is the Geometry on the right hand side being subtracted.

sr - The spatial reference to get the tolerance value from. When sr is null, the tolerance is calculated from the input geometries.

progressTracker - ProgressTracker instance that is used to cancel the lengthy operation. Can be null.

Returns:

Returns the result of subtraction.
