Class GeometryCollectionIterator

java.lang.Object

com.vividsolutions.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.

Specified by:

hasNext in interface Iterator

Returns:

true if more geometry elements remain

next

public Object next()

Gets the next geometry in the iteration sequence.

Specified by:

next in interface Iterator

Returns:

the next geometry in the iteration

remove

public void remove()

Removal is not supported.

Specified by:

remove in interface Iterator

Throws:

UnsupportedOperationException - This method is not implemented.
