Member Function Documentation

◆ add_and_get()

boost::future< int64_t > hazelcast::cp::atomic_long::add_and_get ( int64_t delta )

Atomically adds the given value to the current value.

Parameters

delta the value to add to the current value

Returns: the updated value, the given value added to the current value

◆ alter()

template<typename F >

boost::future<void> hazelcast::cp::atomic_long::alter ( const F & function )

inline

Alters the currently stored value by applying a function on it.

Parameters

function the function applied to the currently stored value

◆ alter_and_get()

template<typename F >

boost::future<int64_t> hazelcast::cp::atomic_long::alter_and_get ( const F & function )

inline

Alters the currently stored value by applying a function on it and gets the result.

Parameters

function the function applied to the currently stored value

Returns: the new value

◆ apply()

template<typename F , typename R >

boost::future<boost::optional<R> > hazelcast::cp::atomic_long::apply ( const F & function )

inline

Applies a function on the value, the actual stored value will not change.

Parameters

function	the function applied to the value, the value is not changed
<R>	the result type of the function

Returns: the result of the function application

◆ compare_and_set()

boost::future< bool > hazelcast::cp::atomic_long::compare_and_set	(	int64_t	expect,
		int64_t	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.

◆ decrement_and_get()

boost::future< int64_t > hazelcast::cp::atomic_long::decrement_and_get ( )

Atomically decrements the current value by one.

Returns: the updated value, the current value decremented by one

◆ get()

boost::future< int64_t > hazelcast::cp::atomic_long::get ( )

Gets the current value.

Returns: the current value

◆ get_and_add()

boost::future< int64_t > hazelcast::cp::atomic_long::get_and_add ( int64_t delta )

Atomically adds the given value to the current value.

Parameters

delta the value to add to the current value

Returns: the old value before the add

◆ get_and_alter()

template<typename F >

boost::future<int64_t> hazelcast::cp::atomic_long::get_and_alter ( const F & function )

inline

Alters the currently stored value by applying a function on it on and gets the old value.

Parameters

function the function applied to the currently stored value

Returns: the old value

Since: 3.2

◆ get_and_decrement()

boost::future< int64_t > hazelcast::cp::atomic_long::get_and_decrement ( )

Atomically decrements the current value by one.

Returns: the old value.

◆ get_and_increment()

boost::future< int64_t > hazelcast::cp::atomic_long::get_and_increment ( )

Atomically increments the current value by one.

Returns: the old value

◆ get_and_set()

boost::future< int64_t > hazelcast::cp::atomic_long::get_and_set ( int64_t new_value )

Atomically sets the given value and returns the old value.

Parameters

newValue the new value

Returns: the old value

◆ increment_and_get()

boost::future< int64_t > hazelcast::cp::atomic_long::increment_and_get ( )

Atomically increments the current value by one.

Returns: the updated value, the current value incremented by one

◆ set()

boost::future< void > hazelcast::cp::atomic_long::set ( int64_t new_value )

Atomically sets the given value.

Parameters

newValue the new value
