◆ SetGlobalReadParam()

void TBufferFile::SetGlobalReadParam ( Int_t  mapsize)
static

Set the initial size of the map used to store object and class references during reading.

The default size is kMapSize. Increasing the default has the benefit that when reading many small objects the array 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). Per TBuffer object this option can be changed using SetReadParam().

◆ SetPidOffset()

void TBufferFile::SetPidOffset ( UShort_t  offset)
virtual

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 referred 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.

◆ SetWriteParam()

void TBufferFile::SetWriteParam ( Int_t  mapsize)
virtual

Set the initial size of the hashtable used to store object and class references during writing.

The default size is TBufferFile::kMapSize. 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. This method can only be called directly after the creation of the TBuffer, before any writing is done.

◆ WriteFloat16()

void TBufferFile::WriteFloat16 ( Float_t f,

virtual

Write a Float16_t to the buffer.

The following cases are supported for streaming a Float16_t type depending on the range declaration in the comment field of the data member:

Case Example
A Float16_t fNormal;
B Float16_t fTemperature; //[0,100]
C Float16_t fCharge; //[-1,1,2]
D Float16_t fVertex[3]; //[-30,30,10]
E Float16_t fChi2; //[0,0,6]
F Int_t fNsp;
Float16_t* fPointValue; //[fNsp][0,3]
  • In case A fNormal is converted from a Float_t to a Float_t with mantissa truncated to 12 bits
  • In case B fTemperature is converted to a 32 bit unsigned integer
  • In case C fCharge is converted to a 2 bits unsigned integer
  • In case D the array elements of fVertex are converted to an unsigned 10 bits integer
  • In case E fChi2 is converted to a Float_t with truncated precision at 6 bits
  • In case F the fNsp elements of array fPointvalue are converted to an unsigned 32 bit integer Note that the range specifier must follow the dimension specifier. Case B has more precision (9 to 10 significative digits than case A (6 to 7 digits).

The range specifier has the general format: [xmin,xmax] or [xmin,xmax,nbits]

  • [0,1];
  • [-10,100];
  • [-pi,pi], [-pi/2,pi/4],[-2pi,2*pi]
  • [-10,100,16]
  • [0,0,8] if nbits is not specified, or nbits <2 or nbits>16 it is set to 16. If (xmin==0 and xmax==0 and nbits <=14) the float word will have its mantissa truncated to nbits significative bits.

IMPORTANT NOTE

NOTE 1

Lets assume an original variable float x: When using the format [0,0,8] (ie range not specified) you get the best relative precision when storing and reading back the truncated x, say xt. The variance of (x-xt)/x will be better than when specifying a range for the same number of bits. However the precision relative to the range (x-xt)/(xmax-xmin) will be worst, and vice-versa. The format [0,0,8] is also interesting when the range of x is infinite or unknown.

NOTE 2

It is important to understand the difference with the meaning of nbits

  • in case of [-1,1,nbits], nbits is the total number of bits used to make the conversion from a float to an integer
  • in case of [0,0,nbits], nbits is the number of bits used for the mantissa

Int_t TBufferFile::WriteObjectAny ( const void obj,

If 'cacheReuse' is true (default) upon seeing an object address a second time, we record the offset where its was written the first time rather than streaming the object a second time.
