◆ regProbePoints()

void PowerModel::regProbePoints ( )

virtual

Register probe points for this object.

No probe points by default, so do nothing in base.

Reimplemented from SimObject.

References SimObject::getProbeManager(), subsystem, and thermalListener.

◆ regStats()

void PowerModel::regStats ( )

inlinevirtual

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.
