#include <bsls_atomic.h>
This class is implements an atomic 64-bit 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::AtomicUint64::AtomicUint64 | ( | ) |
Create an atomic 64-bit unsigned integer object having the default value 0.
| bsls::AtomicUint64::AtomicUint64 | ( | Types::Uint64 | value | ) |
Create an atomic 64-bit unsigned integer object having the specified value.
| bsls::AtomicUint64::~AtomicUint64 | ( | ) |
Destroy this atomic 64-bit unsigned integer object.
| AtomicUint64& bsls::AtomicUint64::operator= | ( | Types::Uint64 | value | ) |
Atomically assign the specified value to this object, and return a reference offering modifiable access to this object.
| Types::Uint64 bsls::AtomicUint64::operator+= | ( | Types::Uint64 | value | ) |
Atomically add the specified value to this object, and return the resulting value.
| Types::Uint64 bsls::AtomicUint64::operator-= | ( | Types::Uint64 | value | ) |
Atomically subtract the specified value from this object, and return the resulting value.
| Types::Uint64 bsls::AtomicUint64::operator++ | ( | ) |
Atomically increment the value of this object by 1 and return the resulting value.
| Types::Uint64 bsls::AtomicUint64::operator++ | ( | int | ) |
Atomically increment the value of this object by 1 and return the value prior to being incremented.
| Types::Uint64 bsls::AtomicUint64::operator-- | ( | ) |
Atomically decrement the value of this object by 1 and return the resulting value.
| Types::Uint64 bsls::AtomicUint64::operator-- | ( | int | ) |
Atomically decrement the value of this object by 1 and return the value prior to being decremented.
| Types::Uint64 bsls::AtomicUint64::add | ( | Types::Uint64 | value | ) |
Atomically add the specified value to this object and return the resulting value.
| Types::Uint64 bsls::AtomicUint64::addRelaxed | ( | Types::Uint64 | value | ) |
Atomically add the specified value to this object and return the resulting value, providing the relaxed memory ordering guarantee.
| Types::Uint64 bsls::AtomicUint64::addAcqRel | ( | Types::Uint64 | value | ) |
Atomically add the specified value to this object and return the resulting value, providing the acquire/release memory ordering guarantee.
| void bsls::AtomicUint64::store | ( | Types::Uint64 | value | ) |
Atomically assign the specified value to this object, providing the sequential consistency memory ordering guarantee.
| void bsls::AtomicUint64::storeRelaxed | ( | Types::Uint64 | value | ) |
Atomically assign the specified value to this object, providing the relaxed memory ordering guarantee.
| void bsls::AtomicUint64::storeRelease | ( | Types::Uint64 | value | ) |
Atomically assign the specified value to this object, providing the release memory ordering guarantee.
| Types::Uint64 bsls::AtomicUint64::subtract | ( | Types::Uint64 | value | ) |
Atomically subtract the specified value from this object and return the resulting value.
| Types::Uint64 bsls::AtomicUint64::subtractAcqRel | ( | Types::Uint64 | value | ) |
Atomically subtract the specified value from this object and return the resulting value, providing the acquire/release memory ordering guarantee.
| Types::Uint64 bsls::AtomicUint64::subtractRelaxed | ( | Types::Uint64 | value | ) |
Atomically subtract the specified value from this object and return the resulting value, providing the relaxed memory ordering guarantee.
| Types::Uint64 bsls::AtomicUint64::swap | ( | Types::Uint64 | swapValue | ) |
Atomically set the value of this object to the specified swapValue and return its previous value.
| Types::Uint64 bsls::AtomicUint64::swapAcqRel | ( | Types::Uint64 | swapValue | ) |
Atomically set the value of this object to the specified swapValue and return its previous value, providing the acquire/release memory ordering guarantee.
| Types::Uint64 bsls::AtomicUint64::testAndSwap | ( | Types::Uint64 | compareValue, | |
| Types::Uint64 | swapValue | |||
| ) |
Compare the value of this object to the specified compareValue. If they are equal, set the value of this atomic 64-bit 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.
| Types::Uint64 bsls::AtomicUint64::testAndSwapAcqRel | ( | Types::Uint64 | compareValue, | |
| Types::Uint64 | swapValue | |||
| ) |
Compare the value of this object to the specified compareValue. If they are equal, set the value of this atomic 64-bit 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::AtomicUint64::operator Types::Uint64 | ( | ) | const |
Return the current value of this object.
| Types::Uint64 bsls::AtomicUint64::load | ( | ) | const |
Return the current value of this object.
| Types::Uint64 bsls::AtomicUint64::loadRelaxed | ( | ) | const |
Return the current value of this object, providing the relaxed memory ordering guarantee.
| Types::Uint64 bsls::AtomicUint64::loadAcquire | ( | ) | const |
Return the current value of this object, providing the acquire memory ordering guarantee.
