class TBits: public TObject
TBits Container of bits This class provides a simple container of bits. Each bit can be set and tested via the functions SetBitNumber and TestBitNumber. . The default value of all bits is kFALSE. The size of the container is automatically extended when a bit number is either set or tested. To reduce the memory size of the container use the Compact function, this will discard the memory occupied by the upper bits that are 0.

Function documentation
void DoAndEqual(const TBits& rhs)
Execute (*this) &= rhs; Extra bits in rhs are ignored Missing bits in rhs are assumed to be zero.
void DoOrEqual(const TBits& rhs)
Execute (*this) &= rhs; Extra bits in rhs are ignored Missing bits in rhs are assumed to be zero.
void DoXorEqual(const TBits& rhs)
Execute (*this) ^= rhs; Extra bits in rhs are ignored Missing bits in rhs are assumed to be zero.
UInt_t FirstNullBit(UInt_t startBit = 0) const
Return position of first null bit (starting from position 0 and up)
UInt_t FirstSetBit(UInt_t startBit = 0) const
Return position of first non null bit (starting from position 0 and up)
void Paint(Option_t* option = "")
Once implemented, it will draw the bit field as an histogram. use the TVirtualPainter as the usual trick
void Set(UInt_t nbits, const Int_t* array)
make nbytes a multiple of 4 so that the loop below is neat.
void Set(UInt_t nbits, const Long64_t* array)
make nbytes a multiple of 8 so that the loop below is neat.
void ResetBitNumber(UInt_t bitnumber)
Bool_t operator[](UInt_t bitnumber) const
TBits::TReference operator[](UInt_t bitnumber)
----- Accessors and operator
{ return TReference(*this,bitnumber); }void Set(UInt_t nbits, const Char_t* array)
----- Optimized setters Each of these will replace the contents of the receiver with the bitvector in the parameter array. The number of bits is changed to nbits. If nbits is smaller than fNbits, the receiver will NOT be compacted.
void Get(Char_t* array) const
----- Optimized getters Each of these will replace the contents of the parameter array with the bits in the receiver. The parameter array must be large enough to hold all of the bits in the receiver. Note on semantics: any bits in the parameter array that go beyond the number of the bits in the receiver will have an unspecified value. For example, if you call Get(Int*) with an array of one integer and the TBits object has less than 32 bits, then the remaining bits in the integer will have an unspecified value.
