class TBasket: public TKey

 Default contructor.

 Constructor used during reading.

 Basket normal constructor, used during writing.

 Basket destructor.

 Increase the size of the current fBuffer up to newsize.

 Copy the basket of this branch onto the file to.

  Delete fEntryOffset array.

 Drop buffers of this basket if it is not the current basket.

 Get pointer to buffer for internal entry.

 Load basket buffers in memory without unziping.
 This function is called by TTreeCloner.
 The function returns 0 in case of success, 1 in case of error.

 Remove the first dentries of this basket, moving entries at
 dentries to the start of the buffer.

 Read basket buffers in memory and cleanup.

 Read a basket buffer. Check if buffers of previous ReadBasket
 should not be dropped. Remember, we keep buffers in memory up to
 fMaxVirtualSize.
 The function returns 0 in case of success, 1 in case of error
 This function was modified with the addition of the parallel
 unzipping, it will try to get the unzipped file from the cache
 receiving only a pointer to that buffer (so we shall not
 delete that pointer), although we get a new buffer in case
 it's not found in the cache.
 There is a lot of code duplication but it was necesary to assure
 the expected behavior when there is no cache.

 Read basket buffers in memory and cleanup

 Read first bytes of a logical record starting at position pos
 return record length (first 4 bytes of record).

 Reset the basket to the starting state. i.e. as it was after calling
 the constructor (and potentially attaching a TBuffer.)

 Set read mode of basket.

 Set write mode of basket.

 Stream a class object.

 Update basket header and EntryOffset table.

 Write buffer of this basket on the current file.

 The function returns the number of bytes committed to the memory.
 If a write error occurs, the number of bytes returned is -1.
 If no data are written, the number of bytes returned is 0.
