BloombergLP::bsls::AtomicOperations_DefaultUint64

Default implementations of non-essential 64-bit unsigned atomic operations.

Synopsis

Declared in <bsls_atomicoperations_default.h>

template<class IMP>
struct AtomicOperations_DefaultUint64;

Description

This class provides default implementations of non-essential atomic operations for the 64-bit unsigned integer type independent on any specific platform. It also provides prototypes for the atomic operations for the 64-bit unsigned integer type that have to be implemented separately for each specific platform. These platform-independent and platform-specific atomic operations together form a full set of atomic operations for the 64-bit unsigned integer type.

Note that AtomicOperations_DefaultUint64 is implemented in terms of the following atomic operations on the Int64 type that must be provided by the IMP template parameter. ` static Types::Int64 getInt64( typename AtomicTypes::Int64 const *atomicInt); static Types::Int64 getInt64Relaxed( typename AtomicTypes::Int64 const *atomicInt); static Types::Int64 getInt64Acquire( typename AtomicTypes::Int64 const *atomicInt); static void setInt64(typename AtomicTypes::Int64 *atomicInt, Types::Int64 value); static void setInt64Relaxed(typename AtomicTypes::Int64 *atomicInt, Types::Int64 value); static void setInt64Release(typename AtomicTypes::Int64 *atomicInt, Types::Int64 value); static Types::Int64 swapInt64(typename AtomicTypes::Int64 *atomicInt, Types::Int64 swapValue); static Types::Int64 swapInt64AcqRel( typename AtomicTypes::Int64 *atomicInt, Types::Int64 swapValue); static Types::Int64 testAndSwapInt64( typename AtomicTypes::Int64 *atomicInt, Types::Int64 compareValue, Types::Int64 swapValue); static Types::Int64 testAndSwapInt64AcqRel( typename AtomicTypes::Int64 *atomicInt, Types::Int64 compareValue, Types::Int64 swapValue); `
