Method Detail

getAndDecrement

double getAndDecrement()

Atomically decrements by one the current value.

Returns:

the previous value

addAndGet

double addAndGet(double delta)

Atomically adds the given value to the current value.

Parameters:

delta - the value to add

Returns:

the updated value

compareAndSet

boolean compareAndSet(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.

decrementAndGet

double decrementAndGet()

Atomically decrements the current value by one.

Returns:

the updated value

get

double get()

Gets the current value.

Returns:

the current value

getAndAdd

double getAndAdd(double delta)

Atomically adds the given value to the current value.

Parameters:

delta - the value to add

Returns:

the old value before the add

getAndSet

double getAndSet(double newValue)

Atomically sets the given value and returns the old value.

Parameters:

newValue - the new value

Returns:

the old value

incrementAndGet

double incrementAndGet()

Atomically increments the current value by one.

Returns:

the updated value

getAndIncrement

double getAndIncrement()

Atomically increments the current value by one.

Returns:

the old value

set

void set(double newValue)

Atomically sets the given value.

Parameters:

newValue - the new value
