Method Summary

static <T> java.lang.Iterable<T>	concat(java.util.Collection<? extends T> iterable, T object) Combines an iterable and an element into a single iterable.
static <T,E extends java.lang.Throwable,F extends java.lang.Throwable> T	find(java.lang.Iterable<T> iterable, DoubleThrowingPredicate<? super T,E,F> predicate, T defaultValue) Returns the first element in iterable that satisfies the given predicate, or defaultValue if none found.
static <T> T	find(java.lang.Iterable<T> iterable, com.google.common.base.Predicate<? super T> predicate, java.lang.String exceptionMessage) Utility method to customize exception message thrown by Iterables.find(Iterable, com.google.common.base.Predicate).
static <T,E extends java.lang.Throwable> T	find(java.lang.Iterable<T> iterable, ThrowingPredicate<? super T,E> predicate, T defaultValue) Returns the first element in iterable that satisfies the given predicate, or defaultValue if none found.

find

public static <T> T find(java.lang.Iterable<T> iterable,
                         com.google.common.base.Predicate<? super T> predicate,
                         @Nullable
                         java.lang.String exceptionMessage)

Utility method to customize exception message thrown by Iterables.find(Iterable, com.google.common.base.Predicate).

concat

public static <T> java.lang.Iterable<T> concat(java.util.Collection<? extends T> iterable,
                                               T object)

Combines an iterable and an element into a single iterable. The returned iterable has an iterator that traverses the elements in a, followed by the elements in b. The source iterator is not polled until necessary. The returned iterable's iterator supports remove() when the corresponding input iterator supports it.
