This class implements an atomic unsigned integer, which supports common unsigned integer 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::AtomicUint::AtomicUint | ( | ) |
Create an atomic unsigned integer object having the default value 0.
| bsls::AtomicUint::AtomicUint | ( | unsigned int | value | ) |
Create an atomic unsigned integer object having the specified value.
| bsls::AtomicUint::~AtomicUint | ( | ) |
Destroy this atomic unsigned integer object.
| AtomicUint& bsls::AtomicUint::operator= | ( | unsigned int | value | ) |
Atomically assign the specified value to this object, and return a reference offering modifiable access to this object.
| unsigned int bsls::AtomicUint::operator+= | ( | unsigned int | value | ) |
Atomically add the specified value to this object, and return the resulting value.
| unsigned int bsls::AtomicUint::operator-= | ( | unsigned int | value | ) |
Atomically subtract the specified value from this object, and return the resulting value.
| unsigned int bsls::AtomicUint::operator++ | ( | ) |
Atomically increment the value of this object by 1 and return the resulting value.
| unsigned int bsls::AtomicUint::operator++ | ( | int | ) |
Atomically increment the value of this object by 1 and return the value prior to being incremented.
| unsigned int bsls::AtomicUint::operator-- | ( | ) |
Atomically decrement the value of this object by 1 and return the resulting value.
| unsigned int bsls::AtomicUint::operator-- | ( | int | ) |
Atomically decrement the value of this object by 1 and return the value prior to being decremented.
| unsigned int bsls::AtomicUint::add | ( | unsigned int | value | ) |
Atomically add the specified value to this object and return the resulting value.
| unsigned int bsls::AtomicUint::addAcqRel | ( | unsigned int | value | ) |
Atomically add the specified value to this object and return the resulting value, providing the acquire/release memory ordering guarantee.
| unsigned int bsls::AtomicUint::addRelaxed | ( | unsigned int | value | ) |
Atomically add the specified value to this object and return the resulting value, providing the relaxed memory ordering guarantee.
| void bsls::AtomicUint::store | ( | unsigned int | value | ) |
Atomically assign the specified value to this object, providing the sequential consistency memory ordering guarantee.
| void bsls::AtomicUint::storeRelaxed | ( | unsigned int | value | ) |
Atomically assign the specified value to this object, providing the relaxed memory ordering guarantee.
| void bsls::AtomicUint::storeRelease | ( | unsigned int | value | ) |
Atomically assign the specified value to this object, providing the release memory ordering guarantee.
| unsigned int bsls::AtomicUint::subtract | ( | unsigned int | value | ) |
Atomically subtract the specified value from this object and return the resulting value.
| unsigned int bsls::AtomicUint::subtractAcqRel | ( | unsigned int | value | ) |
Atomically subtract the specified value from this object and return the resulting value, providing the acquire/release memory ordering guarantee.
| unsigned int bsls::AtomicUint::subtractRelaxed | ( | unsigned int | value | ) |
Atomically subtract the specified value from this object and return the resulting value, providing the relaxed memory ordering guarantee.
| unsigned int bsls::AtomicUint::swap | ( | unsigned int | swapValue | ) |
Atomically set the value of this object to the specified swapValue and return its previous value.
| unsigned int bsls::AtomicUint::swapAcqRel | ( | unsigned int | swapValue | ) |
Atomically set the value of this object to the specified swapValue and return its previous value, providing the acquire/release memory ordering guarantee.
| unsigned int bsls::AtomicUint::testAndSwap | ( | unsigned int | compareValue, | |
| unsigned int | swapValue | |||
| ) |
Compare the value of this object to the specified compareValue. If they are equal, set the value of this atomic unsigned integer to the specified swapValue, otherwise leave this value unchanged. Return the previous value of this atomic unsigned integer, whether or not the swap occurred. Note that the entire test-and-swap operation is performed atomically.
| unsigned int bsls::AtomicUint::testAndSwapAcqRel | ( | unsigned int | compareValue, | |
| unsigned int | swapValue | |||
| ) |
Compare the value of this object to the specified compareValue. If they are equal, set the value of this atomic unsigned integer to the specified swapValue, otherwise leave this value unchanged. Return the previous value of this atomic unsigned integer, 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::AtomicUint::operator unsigned int | ( | ) | const |
Return the current value of this object.
| unsigned int bsls::AtomicUint::load | ( | ) | const |
Return the current value of this object.
| unsigned int bsls::AtomicUint::loadAcquire | ( | ) | const |
Return the current value of this object, providing the acquire memory ordering guarantee.
| unsigned int bsls::AtomicUint::loadRelaxed | ( | ) | const |
Return the current value of this object, providing the relaxed memory ordering guarantee.
