Function documentation

TBufferFile(TBuffer::EMode mode)
 Create an I/O buffer object. Mode should be either TBuffer::kRead or
 TBuffer::kWrite. By default the I/O buffer has a size of
 TBuffer::kInitialSize (1024) bytes.
TBufferFile(TBuffer::EMode mode, Int_t bufsiz)
 Create an I/O buffer object. Mode should be either TBuffer::kRead or
 TBuffer::kWrite.
TBufferFile(TBuffer::EMode mode, Int_t bufsiz, void* buf, Bool_t adopt = kTRUE)
 Create an I/O buffer object. Mode should be either TBuffer::kRead or
 TBuffer::kWrite. By default the I/O buffer has a size of
 TBuffer::kInitialSize (1024) bytes. An external buffer can be passed
 to TBuffer via the buf argument. By default this buffer will be adopted
 unless adopt is false.
~TBufferFile()
 Delete an I/O buffer object.
Int_t GetVersionOwner()
 Return the version number of the owner file.
void IncrementLevel(TVirtualStreamerInfo* info)
 Increment level.
void DecrementLevel(TVirtualStreamerInfo* )
 Decrement level.
void PushDataCache(TVirtualArray* )
 Push a new data cache area onto the list of area to be used for
 temporarily store 'missing' data members.
TVirtualArray * PeekDataCache()
 Return the 'current' data cache area from the list of area to be used for
 temporarily store 'missing' data members.
TVirtualArray * PopDataCache()
 Pop and Return the 'current' data cache area from the list of area to be used for
 temporarily store 'missing' data members.
void ReadLong(Long_t& l)
 Read Long from TBuffer.
void ReadTString(TString& s)
 Read string from TBuffer.
void WriteTString(const TString& s)
 Write string to TBuffer.
void SetByteCount(UInt_t cntpos, Bool_t packInVersion = kFALSE)
 Set byte count at position cntpos in the buffer. Generate warning if
 count larger than kMaxMapCount. The count is excluded its own size.
Int_t CheckByteCount(UInt_t startpos, UInt_t bcnt, const TClass* clss, const char* classname)
 Check byte count with current buffer position. They should
 match. If not print warning and position buffer in correct
 place determined by the byte count. Startpos is position of
 first byte where the byte count is written in buffer.
 Returns 0 if everything is ok, otherwise the bytecount offset
 (< 0 when read too little, >0 when read too much).
Int_t CheckByteCount(UInt_t startpos, UInt_t bcnt, const TClass *clss)
 Check byte count with current buffer position. They should
 match. If not print warning and position buffer in correct
 place determined by the byte count. Startpos is position of
 first byte where the byte count is written in buffer.
 Returns 0 if everything is ok, otherwise the bytecount offset
 (< 0 when read too little, >0 when read too much).
Int_t CheckByteCount(UInt_t startpos, UInt_t bcnt, const char *classname)
 Check byte count with current buffer position. They should
 match. If not print warning and position buffer in correct
 place determined by the byte count. Startpos is position of
 first byte where the byte count is written in buffer.
 Returns 0 if everything is ok, otherwise the bytecount offset
 (< 0 when read too little, >0 when read too much).
void ReadFloat16(Float_t* f, TStreamerElement* ele = 0)
 Read a Float16_t from the buffer,
 see comments about Float16_t encoding at TBufferFile::WriteFloat16().
void ReadDouble32(Double_t* d, TStreamerElement* ele = 0)
 Read a Double32_t from the buffer,
 see comments about Double32_t encoding at TBufferFile::WriteDouble32().
void WriteFloat16(Float_t* f, TStreamerElement* ele = 0)
 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:
  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.
 the 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


/* */
void WriteDouble32(Double_t* d, TStreamerElement* ele = 0)
 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:
  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

  [0,0,8]
 if nbits is not specified, or nbits <2 or nbits>32 it is set to 32
 if (xmin==0 and xmax==0 and nbits <=14) the double word will be converted
 to a float and its mantissa truncated to nbits significative bits.

 IMPORTANT NOTEs

 --NOTE 1
 Lets assume an original variable double 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 double to an integer
  -in case of [0,0,nbits], nbits is the number of bits used for the mantissa

 the objects in the array are of class 'cl'
 'isPreAlloc' indicates whether the data member is marked with '->'
 Return:
  0: success
  2: truncated success (i.e actual class is missing. Only ptrClass saved.)
TObject * ReadObject(const TClass* cl)
 Read object from I/O buffer. clReq is NOT used.
 The value returned is the address of the actual start in memory of
 the object. Note that if the actual class of the object does not
 inherit first from TObject, the type of the pointer is NOT 'TObject*'.
 [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
void SkipObjectAny()
 Skip any kind of object from buffer
void * ReadObjectAny(const TClass* cast)
 Read object from I/O buffer.
 A typical use for this function is:
    MyClass *ptr = (MyClass*)b.ReadObjectAny(MyClass::Class());
 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.
void WriteObject(const TObject* obj)
 Write object to I/O buffer.
void WriteObjectClass(const void* actualObjStart, const TClass* actualClass)
 Write object to I/O buffer.
 This function assumes that the value of 'actualObjectStart' is the actual start of
 the object of class 'actualClass'
Int_t WriteObjectAny(const void* obj, const TClass* ptrClass)
 Write object to I/O buffer.
 This function assumes that the value in 'obj' is the value stored in
 a pointer to a "ptrClass". The actual type of the object pointed to
 can be any class derived from "ptrClass".
 Return:
  0: failure
  1: success
  2: truncated success (i.e actual class is missing. Only ptrClass saved.)
TClass * ReadClass(const TClass* cl = 0, UInt_t* objTag = 0)
 Read class definition from I/O buffer. clReq can be used to cross check
 if the actually read object is of the requested class. objTag is
 set in case the object is a reference to an already read object.
void WriteClass(const TClass* cl)
 Write class description to I/O buffer.
Version_t ReadVersion(UInt_t* start = 0, UInt_t* bcnt = 0, const TClass* cl = 0)
 Read class version from I/O buffer.
UInt_t WriteVersion(const TClass* cl, Bool_t useBcnt = kFALSE)
 Write class version to I/O buffer.
UInt_t WriteVersionMemberWise(const TClass* cl, Bool_t useBcnt = kFALSE)
 Write class version to I/O buffer after setting the kStreamedMemberWise
 bit in the version number.
void StreamObject(void *obj, const type_info &typeinfo, const TClass* onFileClass )
 Stream an object given its C++ typeinfo information.
void StreamObject(void *obj, const char *className, const TClass* onFileClass)
 Stream an object given the name of its actual class.
void StreamObject(void *obj, const TClass *cl, const TClass* onFileClass )
 Stream an object given a pointer to its actual class.
void StreamObject(TObject* obj)
 Stream an object inheriting from TObject using its streamer.
void CheckCount(UInt_t offset)
 Check if offset is not too large (< kMaxMapCount) when writing.
UInt_t CheckObject(UInt_t offset, const TClass* cl, Bool_t readClass = kFALSE)
 Check for object in the read map. If the object is 0 it still has to be
 read. Try to read it from the buffer starting at location offset. If the
 object is -1 then it really does not exist and we return 0. If the object
 exists just return the offset.
void SetBuffer(void* buf, UInt_t bufsiz = 0, Bool_t adopt = kTRUE)
 Sets a new buffer in an existing TBuffer object. If newsiz=0 then the
 new buffer is expected to have the same size as the previous buffer.
 The current buffer position is reset to the start of the buffer.
 If the TBuffer owned the previous buffer, it will be deleted prior
 to accepting the new buffer. By default the new buffer will be
 adopted unless adopt is false.
Bool_t CheckObject(const TObject* obj)
 Check if the specified object is already in the buffer.
 Returns kTRUE if object already in the buffer, kFALSE otherwise
 (also if obj is 0 or TBuffer not in writing mode).
Bool_t CheckObject(const void* obj, const TClass* ptrClass)
 Check if the specified object of the specified class is already in
 the buffer. Returns kTRUE if object already in the buffer,
 kFALSE otherwise (also if obj is 0 ).
void SetPidOffset(UShort_t offset)
 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 refered 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.
void GetMappedObject(UInt_t tag, void*& ptr, TClass*& ClassPtr) const
 Retrieve the object stored in the buffer's object map at 'tag'
 Set ptr and ClassPtr respectively to the address of the object and
 a pointer to its TClass.
void MapObject(const TObject* obj, UInt_t offset = 1)
 Add object to the fMap container.
 If obj is not 0 add object to the map (in read mode also add 0 objects to
 the map). This method may only be called outside this class just before
 calling obj->Streamer() to prevent self reference of obj, in case obj
 contains (via via) a pointer to itself. In that case offset must be 1
 (default value for offset).
void MapObject(const void* obj, const TClass* cl, UInt_t offset = 1)
 Add object to the fMap container.
 If obj is not 0 add object to the map (in read mode also add 0 objects to
 the map). This method may only be called outside this class just before
 calling obj->Streamer() to prevent self reference of obj, in case obj
 contains (via via) a pointer to itself. In that case offset must be 1
 (default value for offset).
void SetReadParam(Int_t mapsize)
 Set the initial size of the map used to store object and class
 references during reading. The default size is kMapSize=503.
 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().
void SetWriteParam(Int_t mapsize)
 Set the initial size of the hashtable used to store object and class
 references during writing. The default size is kMapSize=503.
 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. Globally this option
 can be changed using SetGlobalWriteParam().
void InitMap()
 Create the fMap container and initialize them
 with the null object.
void ResetMap()
 Delete existing fMap and reset map counter.
Int_t ReadBuf(void* buf, Int_t max)
 Read max bytes from the I/O buffer into buf. The function returns
 the actual number of bytes read.
void WriteBuf(const void* buf, Int_t max)
 Write max bytes from buf into the I/O buffer.
Text_t * ReadString(char* s, Int_t max)
 Read string from I/O buffer. String is read till 0 character is
 found or till max-1 characters are read (i.e. string s has max
 bytes allocated). If max = -1 no check on number of character is
 made, reading continues till 0 character is found.
void WriteString(const char* s)
 Write string to I/O buffer. Writes string upto and including the
 terminating 0.
TProcessID * GetLastProcessID(TRefTable* reftable) const
 Return the last TProcessID in the file.
TProcessID * ReadProcessID(UShort_t pidf)
 The TProcessID with number pidf is read from file.
 If the object is not already entered in the gROOT list, it is added.
UInt_t GetTRefExecId()
 Return the exec id stored in the current TStreamerInfo element.
 The execid has been saved in the unique id of the TStreamerElement
 being read by TStreamerElement::Streamer.
 The current element (fgElement) is set as a static global
 by TStreamerInfo::ReadBuffer (Clones) when reading this TRef.
UShort_t WriteProcessID(TProcessID* pid)
 Check if the ProcessID pid is already in the file.
 If not, add it and return the index  number in the local file list.
void ForceWriteInfo(TVirtualStreamerInfo* info, Bool_t force)
 force writing the TStreamerInfo to the file
void ForceWriteInfoClones(TClonesArray* a)
 Make sure TStreamerInfo is not optimized, otherwise it will not be
 possible to support schema evolution in read mode.
 In case the StreamerInfo has already been computed and optimized,
 one must disable the option BypassStreamer.
Int_t ReadClones(TClonesArray* a, Int_t nobjects, Version_t objvers)
 Interface to TStreamerInfo::ReadBufferClones.
Int_t WriteClones(TClonesArray* a, Int_t nobjects)

 Read emulated class.
Int_t ReadClassBuffer(const TClass* cl, void* pointer, Int_t version, UInt_t start, UInt_t count, const TClass* onfile_class)
 Deserialize information from a buffer into an object.

 Note: This function is called by the xxx::Streamer()
       functions in rootcint-generated dictionaries.
   // This function assumes that the class version and the byte count
 information have been read.

   version  is the version number of the class
   start    is the starting position in the buffer b
   count    is the number of bytes for this object in the buffer

Int_t ReadClassBuffer(const TClass* cl, void* pointer, const TClass* onfile_class)
 Deserialize information from a buffer into an object.

 Note: This function is called by the xxx::Streamer()
       functions in rootcint-generated dictionaries.

Int_t WriteClassBuffer(const TClass* cl, void* pointer)
 Function called by the Streamer functions to serialize object at p
 to buffer b. The optional argument info may be specified to give an
 alternative StreamerInfo instead of using the default StreamerInfo
 automatically built from the class definition.
 For more information, see class TStreamerInfo.
void SetGlobalReadParam(Int_t mapsize)
 Set the initial size of the map used to store object and class
 references during reading. The default size is kMapSize=503.
 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().
void SetGlobalWriteParam(Int_t mapsize)
 Set the initial size of the hashtable used to store object and class
 references during writing. The default size is kMapSize=503.
 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.
