Method Detail

getAndDecrement

long getAndDecrement()

Atomically decrements by one the current value.

Returns:

the previous value

addAndGet

long addAndGet(long delta)

Atomically adds the given value to the current value.

Parameters:

delta - the value to add

Returns:

the updated value

compareAndSet

boolean compareAndSet(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.

decrementAndGet

long decrementAndGet()

Atomically decrements the current value by one.

Returns:

the updated value

get

long get()

Gets the current value.

Returns:

the current value

getAndAdd

long getAndAdd(long delta)

Atomically adds the given value to the current value.

Parameters:

delta - the value to add

Returns:

the old value before the add

getAndSet

long getAndSet(long newValue)

Atomically sets the given value and returns the old value.

Parameters:

newValue - the new value

Returns:

the old value

incrementAndGet

long incrementAndGet()

Atomically increments the current value by one.

Returns:

the updated value

getAndIncrement

long getAndIncrement()

Atomically increments the current value by one.

Returns:

the old value

set

void set(long newValue)

Atomically sets the given value.

Parameters:

newValue - the new value
