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 78 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"

Definition at line 212 of file TBufferFile.cxx.

◆ Void_Hash()

static ULong_t Void_Hash ( const void ptr)
inlinestatic

Return hash value for this object.
