Detailed Description

A boolean value that may be updated atomically.

An AtomicBoolean is used in applications such as atomically updated flags, and cannot be used as a replacement for a Boolean.

compareAndSet()

bool decaf::util::concurrent::atomic::AtomicBoolean::compareAndSet	(	bool	expect,
		bool	update
	)

Atomically sets the value to the given updated value if the current value == the expected value.

Parameters

expect	- the expected value
update	- the new value

Returns

true if successful. False return indicates that the actual value was not equal to the expected value.

get()

bool decaf::util::concurrent::atomic::AtomicBoolean::get ( ) const

inline

Gets the current value of this AtomicBoolean.

Returns

the currently set value.

getAndSet()

bool decaf::util::concurrent::atomic::AtomicBoolean::getAndSet

(

bool

newValue

)

Atomically sets to the given value and returns the previous value.

Parameters

newValue
