Class GeometryCollectionIterator

java.lang.Object
org.locationtech.jts.geom.GeometryCollectionIterator
All Implemented Interfaces:
Iterator
public class GeometryCollectionIterator extends Object implements Iterator
Iterates over all Geometrys in a Geometry, (which may be either a collection or an atomic geometry). The iteration sequence follows a pre-order, depth-first traversal of the structure of the GeometryCollection (which may be nested). The original Geometry object is returned as well (as the first object), as are all sub-collections and atomic elements. It is simple to ignore the intermediate GeometryCollection objects if they are not needed.
