_HADES_CLASS_DESCRIPTION

 HBitMan

 library of static functions
 look here for auxiliary functions for:
 bit manipulations.

 The direct bit functions can be used static.
 Bit counting starts at 0. 0 represents the lowest bit.
 The function do not check the range! Take care you
 stay inside the range.
 For the bit functions using names see the following
 example:

  bits in Integer:
  11
  10       tofrec     (no sign)
  9
  8
  7.       charge -1 0 1 (sign)
  6.
  5.       system 0-3 (no sign)
  4........
  3........sector 0-7 (no sign)
  2........
  1........

 // allocate the word map. Bit are allocated
 // in the order of declaration. word width include the
 // extra bit for sign if sign is specified!
 HBitMan bitman;
 bitman.createWord("sector",3,kFALSE);
 bitman.createWord("sys"   ,3,kFALSE);
 bitman.createWord("charge",3,kTRUE);  // 2bits+sign = 3
 bitman.createWord("tofrec",3,kFALSE);
 bitman.init();



 UInt_t common = 0;               // flag integer

 // set values
 bitman.setWord(common,"sector",3);
 bitman.setWord(common,"sys"   ,1);
 bitman.setWord(common,"charge",-1);
 bitman.setWord(common,"tofrec",3);


 bitman.printBits(common); // print binary representation
 cout<<bitman.getWord(common,"sector")<<endl;
 cout<<bitman.getWord(common,"sys")   <<endl;
 cout<<bitman.getWord(common,"charge")<<endl;
 cout<<bitman.getWord(common,"tofrec")<<endl;
 bitman.unsetWord(common,"sector");  // set bits for this word to 0
 bitman.printBits(common);
