CPowerState in SystemService missing?

In SystemService.cpp [components/generic/servicemanager/src/services/systemservice.cpp] there is a #include that I can't find:

#if defined(HAS_API_SYSTEM) && defined(HAS_API_POWERSTATE)
#include "powerstate.h"
#endif

Later on when handling Power Commands we see this, which is not conditional:

else if( method == METHOD_SYSTEM_SET_POWER_STATE && getApiVersionNumber() >= 2 )
 {
 QString powerState;
 QVariantList list = params["params"].toList();
 if(list.length()>0)
 powerState = list.first().toString();

bool ok = CPowerState::instance()->setPowerState(powerState);
 returnResult["success"] = QVariant(ok);
 }

Where can I find this class, which seems to bind the request to the IARM_BUS Power commands served by components/generic/iarmmgrs/power/pwrMgr.c

The code I'm looking at is current as of 7/1/14 and the SHA1 of servicemanager is 6c1255718e4a459070837938307930574e00e49c

Thanks,
