◆ operator[]()

template<typename TP >
const Timer< TP > & walberla::timing::TimingTree< TP >::operator[] ( const std::string &  name) const

tt["firstLevel.secondLevel.thirdLevel.timerName"].total();

◆ reset()

template<typename TP >
void walberla::timing::TimingTree< TP >::reset

Resets the the timing hierarchy.

◆ start()

template<typename TP >
void walberla::timing::TimingTree< TP >::start ( const std::string &  name)

Parameters
nametimer name. '.' is not allowed in the timer name!

◆ stop()

template<typename TP >
void walberla::timing::TimingTree< TP >::stop ( const std::string &  name)
