@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 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 image = imageApi.listInDetail().concat().firstMatch(isInterestingImage());
System.out.println(image.orNull());
...
private static Predicate isInterestingImage() {
return new Predicate() {
@Override
public boolean apply(Image image) {
return image.getName().startsWith("Arch");
}
};
}
