Detailed Description

This is the abstraction layer that exposes GEOPM signals from the SSTIO object.

Member Function Documentation

read()

double geopm::SSTSignal::read ( void  ) const

overridevirtual

Read directly the value of the signal without affecting any pushed batch signals.

Implements geopm::Signal.

sample()

double geopm::SSTSignal::sample ( void  )

overridevirtual

Apply any conversions necessary to interpret the latest stored value as a double.

Implements geopm::Signal.

setup_batch()

void geopm::SSTSignal::setup_batch ( void  )

overridevirtual

Prepare the signal for being updated through side effects by the owner's read_batch step. This method should not fail if called multiple times, and ideally only apply the side effects on the first call.

Implements geopm::Signal.
