TBufferFile::TBufferFile ( TBuffer::EMode mode )

Create an I/O buffer object.

By default this buffer will be adopted unless adopt is false.

The value returned is the address of the actual start in memory of the object.

[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

A typical use for this function is:

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

Write a Double32_t to the buffer.

The following cases are supported for streaming a Double32_t type depending on the range declaration in the comment field of the data member:

Case	Example
A	Double32_t fNormal;
B	Double32_t fTemperature; //[0,100]
C	Double32_t fCharge; //[-1,1,2]
D	Double32_t fVertex[3]; //[-30,30,10]
E	Double32_t fChi2; //[0,0,6]
F	Int_t fNsp; Double32_t* fPointValue; //[fNsp][0,3]

In case A fNormal is converted from a Double_t to a Float_t 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 mantissa 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). See TBufferFile::WriteFloat16 for more information.

◆ 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

See example of use of the Float16_t data type in tutorial double32.C

◆ WriteObjectClass()

void TBufferFile::WriteObjectClass	(	const void *	actualObjectStart,
		const TClass *	actualClass,
		Bool_t	cacheReuse
	)

protectedvirtual

Write object to I/O buffer.

This function assumes that the value of 'actualObjectStart' is the actual start of the object of class 'actualClass' 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. If 'cacheReuse' is false, we always stream the object. This allows the (re)use of temporary object to store different data in the same buffer.
