TBasket()
Default contructor
TBasket(const Text_t *name, const Text_t *title, TBranch *branch)
Basket normal constructor
~TBasket()
Basket destructor
void AdjustSize(Int_t newsize)
Increase the size of the current fBuffer up to newsize
Int_t DropBuffers()
Drop buffers of this basket if it is not the current basket
Int_t GetEntryPointer(Int_t entry)
*-*-*-*-*-*-*Get pointer to buffer for internal entry*-*-*-*-*-*
*-* ========================================
void Print(Option_t *option)
Print Basket parameters
void ReadBasketBuffers()
*-*-*-*-*-*-*-*-*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.
void ReadBasketBuffers(char *buf)
*-*-*-*-*-*-*-*-*Read basket buffers in memory and cleanup*-*-*-*-*-*-*
*-* =========================================
Read a basket buffer from buf. Check if buffers of previous ReadBasket
should not be dropped. Remember, we keep buffers
in memory up to fMaxVirtualSize.
void Reset(Option_t *)
void SetReadMode()
