Examples of AtomicBoolean

edu.emory.mathcs.backport.java.util.concurrent.atomic.AtomicBoolean
A {@code boolean} value that may be updated atomically. See the{@link edu.emory.mathcs.backport.java.util.concurrent.atomic} package specification fordescription of the properties of atomic variables. An {@code AtomicBoolean} is used in applications such as atomicallyupdated flags, and cannot be used as a replacement for a {@link java.lang.Boolean}. @since 1.5 @author Doug Lea
