Method Detail

asyncAddAndGet

ICompletableFuture<Long> asyncAddAndGet(long delta)

Atomically adds the given value to the current value.

Parameters:

delta - the value to add

Returns:

the updated value

asyncCompareAndSet

ICompletableFuture<Boolean> asyncCompareAndSet(long expect,
                                             long 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.

asyncDecrementAndGet

ICompletableFuture<Long> asyncDecrementAndGet()

Atomically decrements the current value by one.

Returns:

the updated value

asyncGet

ICompletableFuture<Long> asyncGet()

Gets the current value.

Returns:

the current value

asyncGetAndAdd

ICompletableFuture<Long> asyncGetAndAdd(long delta)

Atomically adds the given value to the current value.

Parameters:

delta - the value to add

Returns:

the old value before the add

asyncGetAndSet
