getAndSet

public final int getAndSet(int i,
            int newValue)

Atomically sets the element at position i to the given value and returns the old value.

Parameters:

i - the index

newValue - the new value

Returns:

the previous value

compareAndSet

public final boolean compareAndSet(int i,
                    int expect,
                    int update)

Atomically sets the element at position i to the given updated value if the current value == the expected value.

Parameters:

i - the index

expect - the expected value

update - the new value
