Java Source Code / Java Documentation » GIS » GeoTools 2.4.1 » org.geotools.resources   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.util.AbstractSet    org.geotools.resources.LazySet LazySet final public class LazySet extends AbstractSet (Code) An immutable set built from an iterator, which will be filled only when needed. This implementation do not check if all elements in the iterator are really unique; we assume that it was already verified by javax.imageio.spi.ServiceRegistry . This set is constructed by org.geotools.referencing.FactoryFinder . since:    2.0 version:    $Id: LazySet.java 22443 2006-10-27 20:47:22Z desruisseaux $ author:    Martin Desruisseaux Constructor Summary public   LazySet(Iterator iterator)      Construct a set to be filled using the specified iterator. Method Summary final  boolean exists(int index)      Returns true if an element exists at the given index. public  Object get(int index)      Returns the element at the specified position in this set. public  boolean isEmpty()      Tests if this set has no elements. public  Iterator iterator()      Returns an iterator over the elements contained in this set. public  int size()      Returns the number of elements in this set. Constructor Detail LazySet public LazySet(Iterator iterator)(Code) Construct a set to be filled using the specified iterator. Iteration in the given iterator will occurs only when needed. Method Detail exists final boolean exists(int index)(Code) Returns true if an element exists at the given index. The element is not loaded immediately. NOTE: This method is for use by iterators only. It is not suited for more general usage since it doesn't check for negative index and for skipped elements. get public Object get(int index)(Code) Returns the element at the specified position in this set. isEmpty public boolean isEmpty()(Code) Tests if this set has no elements. iterator public Iterator iterator()(Code) Returns an iterator over the elements contained in this set. This is not the same iterator than the one given to the constructor. size public int size()(Code) Returns the number of elements in this set. Invoking this method force the set to immediately iterates through all remaining elements.
