Interface GeometryOperation

All Known Implementing Classes:

BufferValidatedGeometryOperation, GeometryFunctionOperation, GeometryMethodOperation, LoggingGeometryOperation, OverlayValidatedGeometryOperation, PreparedGeometryOperation, PreparedGeometryTeeOperation, TeeGeometryOperation

public interface GeometryOperation

Interface for classes which execute operations on Geometrys. The arguments may be presented as Strings, even if they should be calling a method with non-String arguments. Geometry will always be supplied as Geometry objects, however. This interface abstracts out the invocation of a method on a Geometry during a Test. Subclasses can provide substitute or additional methods during runs of the same test file.
