@Beta public abstract class PagedIterable<E> extends com.google.common.collect.FluentIterable<IterableWithMarker<E>>
FluentIterable
allowing you to lazily advance through
sequence of pages in a result set. Typically used in APIs that return only a
certain number of records at a time.
Simplest usage is to employ the concat()
convenience function, and iterate.
FluentIterable extends Image> images = imageApi.listInDetail().concat(); for (Image image: images) { System.out.println(image); }Another usage is to employ the
concat()
convenience function, and one
of the methods from FluentIterable
.
Optional extends Image> image = imageApi.listInDetail().concat().firstMatch(isInterestingImage()); System.out.println(image.orNull()); ... private static PredicateisInterestingImage() { return new Predicate () { @Override public boolean apply(Image image) { return image.getName().startsWith("Arch"); } }; }
