Class GeometryCollectionIterator

  • All Implemented Interfaces:
    java.util.Iterator
    public class GeometryCollectionIterator
extends java.lang.Object
implements java.util.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.
