Class LazyIterable<T>

java.lang.Object

com.spectralogic.ds3client.utils.collections.LazyIterable<T>

All Implemented Interfaces:

java.lang.Iterable<T>

public class LazyIterable<T>
extends java.lang.Object
implements java.lang.Iterable<T>

Produces an Iterator that will lazily load content. Our definition of lazy for this class, is that the Iterator is returned right away with no data. Data is only then loaded, as needed, in pieces as defined by the LazyIterableLoader. To use, supply a LazyIterable.LazyLoaderFactory which is used to fetch data as it is needed.
