Member Function Documentation

DDLogicalPart DDRoot::root ( ) const

returns the root of the geometrical hierarchy

To find out, whether the root was already defined or not:

DDLogicalPart root;
if(root=DDRoot::instance().root()) { // ok, root was already defined
  // so something here ...
}
else { // root has not been defined yet!
  // do something else
}
