| ↳ | java.util.concurrent.atomic.AtomicBoolean |
A boolean value that may be updated atomically. See the
java.util.concurrent.atomic package specification for
description of the properties of atomic variables. An
AtomicBoolean is used in applications such as atomically
updated flags, and cannot be used as a replacement for a
Boolean.
