This class implements an atomic boolean, which supports common boolean operations in a way that is guaranteed to be atomic. Operations on objects of this class provide the sequential consistency memory ordering guarantee unless explicitly qualified with a less strict consistency guarantee suffix (i.e., Acquire, Release, AcqRel or Relaxed).
| bsls::AtomicBool::AtomicBool | ( | ) |
Create an atomic boolean object having the default value false.
| bsls::AtomicBool::AtomicBool | ( | bool | value | ) |
Create an atomic boolean object having the specified value.
| bsls::AtomicBool::~AtomicBool | ( | ) |
Destroy this atomic boolean object.
| AtomicBool& bsls::AtomicBool::operator= | ( | bool | value | ) |
Atomically assign the specified value to this object, and return a reference offering modifiable access to this object.
| void bsls::AtomicBool::store | ( | bool | value | ) |
Atomically assign the specified value to this object, providing the sequential consistency memory ordering guarantee.
| void bsls::AtomicBool::storeRelaxed | ( | bool | value | ) |
Atomically assign the specified value to this object, providing the relaxed memory ordering guarantee.
| void bsls::AtomicBool::storeRelease | ( | bool | value | ) |
Atomically assign the specified value to this object, providing the release memory ordering guarantee.
| bool bsls::AtomicBool::swap | ( | bool | swapValue | ) |
Atomically set the value of this object to the specified swapValue and return its previous value.
| bool bsls::AtomicBool::swapAcqRel | ( | bool | swapValue | ) |
Atomically set the value of this object to the specified swapValue and return its previous value, providing the acquire/release memory ordering guarantee.
| bool bsls::AtomicBool::testAndSwap | ( | bool | compareValue, | |
| bool | swapValue | |||
| ) |
Compare the value of this object to the specified compareValue. If they are equal, set the value of this atomic boolean to the specified swapValue, otherwise leave this value unchanged. Return the previous value of this atomic boolean, whether or not the swap occurred. Note that the entire test-and-swap operation is performed atomically.
| bool bsls::AtomicBool::testAndSwapAcqRel | ( | bool | compareValue, | |
| bool | swapValue | |||
| ) |
Compare the value of this object to the specified compareValue. If they are equal, set the value of this atomic boolean to the specified swapValue, otherwise leave this value unchanged. Return the previous value of this atomic boolean, whether or not the swap occurred. Note that the entire test-and-swap operation is performed atomically and it provides the acquire/release memory ordering guarantee.
| bsls::AtomicBool::operator bool | ( | ) | const |
Return the current value of this object.
| bool bsls::AtomicBool::load | ( | ) | const |
Return the current value of this object.
| bool bsls::AtomicBool::loadRelaxed | ( | ) | const |
Return the current value of this object, providing the relaxed memory ordering guarantee.
| bool bsls::AtomicBool::loadAcquire | ( | ) | const |
Return the current value of this object, providing the acquire memory ordering guarantee.
