Function Documentation

◆ Class_Has_StreamerInfo()

static bool Class_Has_StreamerInfo ( const TClass cl)
inlinestatic

Thread-safe check on StreamerInfos of a TClass.

Definition at line 63 of file TBufferFile.cxx.

◆ frombufOld()

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"
