Modifier and Type	Method and Description
`static <T> com.google.common.base.Predicate<T>`	`retry(com.google.common.base.Predicate<T> findOrBreak, long timeout)` like `retry(Predicate, long, long, long, TimeUnit)` where `unit` is in milliseconds, `period` is 50ms, and `maxPeriod` 1s.
`static <T> com.google.common.base.Predicate<T>`	`retry(com.google.common.base.Predicate<T> findOrBreak, long timeout, long period, long maxPeriod)` like `retry(Predicate, long, long, long, TimeUnit)` where `unit` is in milliseconds
`static <T> com.google.common.base.Predicate<T>`	`retry(com.google.common.base.Predicate<T> findOrBreak, long timeout, long period, long maxPeriod, TimeUnit unit)` Retries a predicate until it is met, a timeout occurs, or an exception occurs.
`static <T> com.google.common.base.Predicate<T>`	`retry(com.google.common.base.Predicate<T> findOrBreak, long timeout, long period, TimeUnit unit)` like `retry(Predicate, long, long, long, TimeUnit)` where `maxPeriod` is 10x `period`
`static com.google.common.base.Predicate<String>`	`startsWith(String prefix)` Returns a predicate that evaluates to true if the String being tested starts with a prefix.
