Member Function Documentation

bool DUNE::Concurrency::AtomicInteger::compareAndSwap ( long  expected,
long  val 
)
inline

Exchange the internal value with a new one if it matches an expected value.

Parameters
expectedexpected value.
valexchange value.
Returns
true if an exchange took place, false otherwise.
long DUNE::Concurrency::AtomicInteger::decrement ( void  )
inline

Decrement the internal value by 1.

Returns
new value of the integer.

Referenced by decrementAndCompare().

bool DUNE::Concurrency::AtomicInteger::decrementAndCompare ( long  val = 0)
inline

Decrement the internal value by 1 and compare with a value.

Parameters
valcomparison value.
Returns
true if the result of the decrementation and comparison value are equal, false otherwise.

long DUNE::Concurrency::AtomicInteger::increment ( void  )
inline

Increment the internal value by 1.

Returns
new value of the integer.

bool DUNE::Concurrency::AtomicInteger::incrementAndCompare ( long  val = 0)
inline

Increment the internal value by 1 and compare with a value.

Parameters
valcomparison value.
