type

AtomicInt

src @Js const class AtomicInt : Obj

AtomicInt is used to manage an integer variable shared between actor/threads with atomic updates.

constructors

make	Construct with initial value

fields

val	The current integer value

methods

add	Atomically add the given value to the current value
addAndGet	Atomically add the given value to the current value and return the updated value.
compareAndSet	Atomically set the value to `update` if current value is equivalent to the `expect` value.
decrement	Atomically decrement the value by one
decrementAndGet	Atomically decrement the current value by one and return the updated value.
getAndAdd	Atomically add the given value to the current value and return the previous value.
getAndDecrement	Atomically decrement the current value by one and return the previous value.
getAndIncrement	Atomically increment the current value by one and return the previous value.
getAndSet	Atomically set the value and return the previous value.
increment	Atomically increment the value by one
incrementAndGet	Atomically increment the current value by one and return the updated value.
toStr	Return `val.toStr`

Slot Details

add

src Void add(Int delta)

Atomically add the given value to the current value

addAndGet

src Int addAndGet(Int delta)

Atomically add the given value to the current value and return the updated value.

compareAndSet

src Bool compareAndSet(Int expect, Int update)

Atomically set the value to update if current value is equivalent to the expect value. Return true if updated, or false if current value was not equal to the expected value.

decrement

src Void decrement()

Atomically decrement the value by one

decrementAndGet

src Int decrementAndGet()

Atomically decrement the current value by one and return the updated value.

getAndAdd

src Int getAndAdd(Int delta)

Atomically add the given value to the current value and return the previous value.

getAndDecrement

src Int getAndDecrement()

Atomically decrement the current value by one and return the previous value.

getAndIncrement

src Int getAndIncrement()

Atomically increment the current value by one and return the previous value.

getAndSet

src Int getAndSet(Int val)

Atomically set the value and return the previous value.

increment

src Void increment()

Atomically increment the value by one

incrementAndGet

src Int incrementAndGet()

Atomically increment the current value by one and return the updated value.

make

src new make(Int val := 0)

Construct with initial value

toStr

src virtual override Str toStr()

Return val.toStr

val

src Int val

The current integer value
