const

Return hash value for this object.

static void frombufOld ( char *&  buf, Long_t *  x  )

static

Handle old file formats.

Files written with versions older than 3.00/06 had a non-portable implementation of Long_t/ULong_t. These types should not have been used at all. However, because some users had already written many files with these types we provide this dirty patch for "backward compatibility"
