Member Function Documentation

bool PHGeomTGeo::ConsistencyCheck

(

)

const

Since ROOT force TGeoManager is a unique object via global pointer gGeoManager, this function checks whether _fGeom is still the current gGeoManager which avoids operates on an invalid pointer

)

Assign TGeoManager object. Once assigned, the TGeoManager will be locked to avoid a second TGeoManager override gGeoManager and lead to an invalid PHGeomTGeo The pointer TGeoManager should be the current gGeoManager
