TBuffer

 Create an I/O buffer object. Mode should be either TBuffer::kRead or
 TBuffer::kWrite. By default the I/O buffer has a size of
 TBuffer::kInitialSize (1024) bytes.

 Create an I/O buffer object. Mode should be either TBuffer::kRead or
 TBuffer::kWrite. By default the I/O buffer has a size of
 TBuffer::kInitialSize (1024) bytes. An external buffer can be passed
 to TBuffer via the buf argument. By default this buffer will be adopted
 unless adopt is false.

 TBuffer copy ctor.

 TBuffer assignment operator.
return *this;

 Delete an I/O buffer object.

operator >>

 Sets a new buffer in an existing TBuffer object. If newsiz=0 then the
 new buffer is expected to have the same size as the previous buffer.
 The current buffer position is reset to the start of the buffer.
 If the TBuffer owned the previous buffer, it will be deleted prior
 to accepting the new buffer. By default the new buffer will be
 adopted unless adopt is false.

 Check if offset is not too large (< kMaxMapCount) when writing.

 Check for object in the read map. If the object is 0 it still has to be
 read. Try to read it from the buffer starting at location offset. If the
 object is -1 then it really does not exist and we return 0. If the object
 exists just return the offset.

 Check if the specified object is already in the buffer.
 Returns kTRUE if object already in the buffer, kFALSE otherwise
 (also if obj is 0 or TBuffer not in writing mode).

 Check if the specified object of the specified class is already in
 the buffer. Returns kTRUE if object already in the buffer,
 kFALSE otherwise (also if obj is 0 ).

 Expand the I/O buffer to newsize bytes.

 Return pointer to parent of this buffer.

 Set parent owning this buffer.

 This offset is used when a key (or basket) is transfered from one
 file to the other.  In this case the TRef and TObject might have stored a
 pid index (to retrieve TProcessIDs) which refered to their order on the original
 file, the fPidOffset is to be added to those values to correctly find the
 TProcessID.  This fPidOffset needs to be increment if the key/basket is copied
 and need to be zero for new key/basket.

 Retrieve the object stored in the buffer's object map at 'tag'
 Set ptr and ClassPtr respectively to the address of the object and
 a pointer to its TClass.

 Add object to the fMap container.
 If obj is not 0 add object to the map (in read mode also add 0 objects to
 the map). This method may only be called outside this class just before
 calling obj->Streamer() to prevent self reference of obj, in case obj
 contains (via via) a pointer to itself. In that case offset must be 1
 (default value for offset).

 Add object to the fMap container.
 If obj is not 0 add object to the map (in read mode also add 0 objects to
 the map). This method may only be called outside this class just before
 calling obj->Streamer() to prevent self reference of obj, in case obj
 contains (via via) a pointer to itself. In that case offset must be 1
 (default value for offset).

 Set the initial size of the map used to store object and class
 references during reading. The default size is kMapSize=503.
 Increasing the default has the benefit that when reading many
 small objects the map does not need to be resized too often
 (the system is always dynamic, even with the default everything
 will work, only the initial resizing will cost some time).
 This method can only be called directly after the creation of
 the TBuffer, before any reading is done. Globally this option
 can be changed using SetGlobalReadParam().

 Set the initial size of the hashtable used to store object and class
 references during writing. The default size is kMapSize=503.
 Increasing the default has the benefit that when writing many
 small objects the hashtable does not get too many collisions
 (the system is always dynamic, even with the default everything
 will work, only a large number of collisions will cost performance).
 For optimal performance hashsize should always be a prime.

 Create the fMap container and initialize them
 with the null object.

increment level

 Delete existing fMap and reset map counter.

 Set byte count at position cntpos in the buffer. Generate warning if
 count larger than kMaxMapCount. The count is excluded its own size.

 Check byte count with current buffer position. They should
 match. If not print warning and position buffer in correct
 place determined by the byte count. Startpos is position of
 first byte where the byte count is written in buffer.
 Returns 0 if everything is ok, otherwise the bytecount offset
 (< 0 when read too little, >0 when read too much).

 Read max bytes from the I/O buffer into buf. The function returns
 the actual number of bytes read.

 Write max bytes from buf into the I/O buffer.

 Read string from I/O buffer. String is read till 0 character is
 found or till max-1 characters are read (i.e. string s has max
 bytes allocated). If max = -1 no check on number of character is
 made, reading continues till 0 character is found.

 Write string to I/O buffer. Writes string upto and including the
 terminating 0.

 allocated for the array.

 Skip any kind of object from buffer

 Read object from I/O buffer.
 A typical use for this function is:
    MyClass *ptr = (MyClass*)b.ReadObjectAny(MyClass::Class());
 I.e. clCast should point to a TClass object describing the class pointed
 to by your pointer.
 In case of multiple inheritance, the return value might not be the
 real beginning of the object in memory.  You will need to use a
 dynamic_cast later if you need to retrieve it.
