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.

Definition at line 52 of file TBuffer.cxx.

◆ TBuffer() [4/5]

TBuffer::TBuffer	(	EMode	mode,

Create an I/O buffer object.

Mode should be either TBuffer::kRead or TBuffer::kWrite.

Definition at line 73 of file TBuffer.cxx.

◆ TBuffer() [5/5]

TBuffer::TBuffer	(	EMode	mode,
		Int_t	bufsiz,
		void *	buf,
		Bool_t	adopt = kTRUE,
		ReAllocCharFun_t	reallocfunc = nullptr )

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.

If the new buffer is not adopted and no memory allocation routine is provided, a Fatal error will be issued if the Buffer attempts to expand.

◆ AutoExpand()

void TBuffer::AutoExpand ( Int_t size_needed )

Automatically calculate a new size and expand the buffer to fit at least size_needed.

The goals is to minimize the number of memory allocation and the memory allocation which avoiding too much memory wastage.

If the size_needed is larger than the current size, the policy is to expand to double the current size or the size_needed which ever is largest.

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.

If the new buffer is not adopted and no memory allocation routine is provided, a Fatal error will be issued if the Buffer attempts to expand.

◆ Write() [1/2]

Int_t TBuffer::Write	(	const char *	name,
		Int_t	option,
		Int_t	bufsize ) const

inlineoverrideprotectedvirtual

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
The TBuffer object is filled via the class::Streamer function.
If the file is compressed (default) a second buffer is created to hold the compressed buffer.
Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.
