◆ MemCtrlStats()

QoS::MemCtrl::MemCtrlStats::MemCtrlStats ( MemCtrl & mc )

Member Function Documentation

◆ regStats()

void QoS::MemCtrl::MemCtrlStats::regStats ( )

overridevirtual

Callback to set stat parameters.

This callback is typically used for complex stats (e.g., distributions) that need parameters in addition to a name and a description. Stat names and descriptions should typically be set from the constructor usingo from the constructor using the ADD_STAT macro.

Reimplemented from Stats::Group.
