[More accurately, the class needs to start with the TObject part, for the pointer to be a real TObject*]. We recommend using ReadObjectAny instead of ReadObject

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.

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.

◆ SetReadParam()

void TBufferFile::SetReadParam ( Int_t mapsize )

virtual

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

The default size is TBufferFile::kMapSize. 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().

◆ 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.

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. Globally this option can be changed using SetGlobalWriteParam().

◆ WriteFloat16()

void TBufferFile::WriteFloat16	(	Float_t *	f,
		TStreamerElement *	ele = `0`
	)

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
