Method Detail

compareAndSetAsync

RFuture<Boolean> compareAndSetAsync(double expect,
                                    double update)

Atomically sets the value to the given updated value only if the current value == the expected value.

Parameters:

expect - the expected value

update - the new value

Returns:

true if successful; or false if the actual value was not equal to the expected value.
