Class 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.

    • Constructor Detail

      • GeometryCollectionIterator

        public GeometryCollectionIterator​(Geometry parent)
        Constructs an iterator over the given Geometry.
        Parameters:
        parent - the geometry over which to iterate; also, the first element returned by the iterator.

    • Method Detail

      • hasNext

        public boolean hasNext()
        Tests whether any geometry elements remain to be returned.
        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
