Class ClipOperation

java.lang.Object

org.gvsig.geoprocess.algorithm.base.core.GeometryOperation

org.gvsig.geoprocess.algorithm.clip.ClipOperation

public class ClipOperation
extends GeometryOperation

This class analyzes all features of a layer, clipping its geometries with the convex hull of another layer. If the geometry of the feature analyzed doesnt intersect with the convex hull geometry, the clipvisitor will ignore it. It intersects, computes intersection and creates a new feature with the same attributes and the new intersection geometry.

invoke

public EditableFeature invoke(Geometry g,
                              Feature feature)

clips feature's geometry with the clipping geometry, preserving feature's original attributes. If feature's geometry doesnt touch clipping geometry, it will be ignored.

Specified by:

invoke in class GeometryOperation

Returns:
