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.

Constructor & Destructor Documentation

decaf::util::concurrent::atomic::AtomicBoolean::AtomicBoolean ( )

Creates a new AtomicBoolean whose initial value is false.

decaf::util::concurrent::atomic::AtomicBoolean::AtomicBoolean ( bool initialValue )

Creates a new AtomicBoolean with the initial value.

Parameters

initialValue - The initial value of this boolean.

virtual decaf::util::concurrent::atomic::AtomicBoolean::~AtomicBoolean ( )

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.

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

inline

Gets the current value of this AtomicBoolean.

bool decaf::util::concurrent::atomic::AtomicBoolean::getAndSet ( bool newValue )

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

Parameters

newValue - the new value

void decaf::util::concurrent::atomic::AtomicBoolean::set ( bool newValue )

inline

Unconditionally sets to the given value.

Parameters

newValue - the new value

std::string decaf::util::concurrent::atomic::AtomicBoolean::toString ( ) const

Returns the String representation of the current value.
