public final boolean get()
public final boolean compareAndSet(boolean expect, boolean update)
==
the expected value.
expect
- the expected valueupdate
- the new value
public boolean weakCompareAndSet(boolean expect, boolean update)
==
the expected value.
May fail spuriously
and does not provide ordering guarantees, so is only rarely an
appropriate alternative to compareAndSet
.
