void GeoVPhysVol::apply

(

GeoVolumeAction *

action

)

const

Applies an action to the volume. The volume executes the action and the applies it to the children, either from the top down or the bottom up, depending upon the configuration of the action.

void GeoVPhysVol::dockTo ( GeoVPhysVol *  parent )

virtual

When a node is added to a parent in the graph, the node is always notified. What happens at that time is up to the node. Most nodes do not need to do anything. Some–the alignable transforms in particular–need to take some actions, such as adding the parent volume to a list.

Reimplemented from GeoGraphNode.

  if(m_parentPtr) {
    m_parentPtr = this;
  }
  else {
    m_parentPtr = parent;
  }
}

Query< unsigned int > GeoVPhysVol::indexOf

(

PVConstLink

daughter

)

const

Returns the index of a specific daughter volume. The Query class can be used just like an unsigned int, but it provides and isValid() method to determine whether it is valid and throws an exception if an invalid value is blithely used.

Definition at line 24 of file GeoVPhysVol.cxx.

{
  unsigned int nChildVols{getNChildVols()};
  for(unsigned int i=0; i<nChildVols; i++) { // To Do: replace this with Volume Iterator!
    if(getChildVol(i) == daughter) return i;
  }
  return Query<unsigned int >();
}

bool GeoVPhysVol::isShared ( ) const

inline

Returns true if the physical volume is accessed by more than one parent. Should check this before trusting the parent pointer.

Definition at line 101 of file GeoVPhysVol.h.

{
  return m_parentPtr == this;
}
