Detailed Description

Convenient helper class for setting single bits in a 32bit-field, such as collection flags or hit types - extends std::bitset<32>.

Use convenient methods make_bitset32(...) to create a bit set with some bits set.
Examples:

  // set collection flags :
  LCCollectionVec* calVec = new LCCollectionVec( LCIO::SIMCALORIMETERHIT )  ;
  calVec->setFlag( UTIL::make_bitset32(  LCIO::CHBIT_LONG, LCIO::CHBIT_STEP ) );

  // check TrackerHit type:
  BitSet32 type( hit->getType() ) ;
  bool isComposite = type.test( ILDTrkHitTypeBit::COMPOSITE_SPACEPOINT ) ; // test w/ range check
  // or shorter:
  if( BitSet32( hit->getType() )[ ILDTrkHitTypeBit::COMPOSITE_SPACEPOINT ] ) {...}
