Describes a persistent version of a class.
A ROOT file contains the list of TStreamerInfo objects for all the class versions written to this file. When reading a file, all the TStreamerInfo objects are read back in memory and registered to the TClass list of TStreamerInfo. One can see the list and contents of the TStreamerInfo on a file with, e.g.,
A TStreamerInfo is a list of TStreamerElement objects (one per data member or base class). When streaming an object, the system (TClass) loops on all the TStreamerElement objects and calls the appropriate function for each element type.

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.
In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.
The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();
(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

Recalculate the checksum of this TStreamerInfo based on its code.
The class ckecksum is used by the automatic schema evolution algorithm to uniquely identify a class version. The check sum is built from the names/types of base classes and data members. The valid range of code is determined by ECheckSum.
This is needed for backward compatibility.
This function must be kept in sync with TClass::GetCheckSum. They are both used to handle backward compatibility and should both return the same values. TStreamerInfo uses the information in TStreamerElement while TClass uses the information from TClass::GetListOfBases and TClass::GetListOfDataMembers.

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:
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.

The object at pointer is serialized to the buffer b if (arrayMode & 1) ptr is a pointer to array of pointers to the objects otherwise it is a pointer to a pointer to a single object.
This also means that T is of a type such that arr[i] is a pointer to an object. Currently the only anticipated instantiation are for T==char** and T==TVirtualCollectionProxy
