Detailed Description

Entity comparison criterion for STL container.

This class is a functor to be used in STL containers of Entity* whenever determinism is required (as an alternative to the object's pointer). If a NULL pointer is passed as argument, it's id is computed as zero, it is a failsafe and should be avoided.

typedef  std::map<Net*,SomeValue,Entity::CompareById>  NetMap;
 
NetMap  netMap;
forEach( Net*, inet, cell->getNets() ) {
  netMap.insert( std::make_pair(*inet,computeSomeValue(*inet)) );
}
 
for ( NetMap::iterator imap=netMap.begin() ; imap!=netMap.end() ; ++imap ) {
  // Show the Net ordering
  cout << (*imap).first->getId() << ":" << (*imap).first << endl;
  // Do something
  // ...
}
