Detailed Description

A mutable object that may contain a value to another object. It is modifiable exactly once and must hold a non-null value when the value is inspected.

Holders are intended for receiving a result from an anonymous class.

Note that Holder is not thread safe. For a thread safe implementation, use AtomicReference. Also note that two different Holder instances are never considered equal.
