- All Implemented Interfaces:
java.util.Iterator
public class GeometryCollectionIterator extends java.lang.Object implements java.util.Iterator
Iterates over allGeometry
s in aGeometry
, (which may be either a collection or an atomic geometry). The iteration sequence follows a pre-order, depth-first traversal of the structure of theGeometryCollection
(which may be nested). The originalGeometry
object is returned as well (as the first object), as are all sub-collections and atomic elements. It is simple to ignore the intermediateGeometryCollection
objects if they are not needed.- Version:

- the next geometry in the iteration
-
remove
public void remove()
Removal is not supported.- Specified by:
remove
in interfacejava.util.Iterator
