virtual bool isDone() const =0
Reports whether the application of this filter can be terminated.
virtual void filter_ro(const CoordinateSequence &, std::size_t)
Performs an operation on a coordinate in a CoordinateSequence.
Definition: CoordinateSequenceFilter.h:81
virtual void filter_rw(CoordinateSequence &, std::size_t)
Performs an operation on a coordinate in a CoordinateSequence.
Definition: CoordinateSequenceFilter.h:69
virtual bool isGeometryChanged() const =0
Reports whether the execution of this filter has modified the coordinates of the geometry.
The internal representation of a list of coordinates inside a Geometry.
