ROOT::TSpinMutex Class Reference
Parallelized classes

A spin mutex class which respects the STL interface for mutexes.

This class allows to acquire spin locks also in combination with templates in the STL such as std::unique_lock or std::condition_variable_any. For example:

ROOT::TSpinMutex m;
std::condition_variable cv;
bool ready = false;
void worker_thread()
{
// Wait until main() sends data
std::unique_lock<ROOT::TSpinMutex> lk(m);
cv.wait(lk, []{return ready;});
[...]
}
TRangeDynCast
ROOT::Detail::TRangeCast< T, true > TRangeDynCast
TRangeDynCast is an adapter class that allows the typed iteration through a TCollection.
