TBufferSQL2

 Default constructor, should not be used

 Creates buffer object to serailize/deserialize data to/from sql.
 Mode should be either TBuffer::kRead or TBuffer::kWrite.

 Creates buffer object to serailize/deserialize data to/from sql.
 This constructor should be used, if data from buffer supposed to be stored in file.
 Mode should be either TBuffer::kRead or TBuffer::kWrite.

 destroy sql buffer

 Convert object of any class to sql structures
 Return pointer on created TSQLStructure
 TSQLStructure object will be owned by TBufferSQL2

 Recreate object from sql structure.
 Return pointer to read object.
 if (cl!=0) returns pointer to class of object

 Returns object info like classname and version
 Should be taken from buffer, which is produced in the begginnig

 creates TSQLObjectData for specifed object id and specified class
 Object data for each class can be stored in two different tables.
 First table contains data in column-wise form for simple types like integer,
 strings and so on when second table contains any other data which cannot
 be converted into column-wise representation.
 TSQLObjectData will contain results of the requests to both such tables for
 concrete object id.

 Convert object into sql structures.
 !!! Should be used only by TBufferSQL2 itself.
 Use SqlWrite() functions to convert your object to sql
 Redefined here to avoid gcc 3.x warning

 Write object to buffer
 If object was written before, only pointer will be stored
 Return id of saved object

 Read object from the buffer

 Read object data.
 Class name and version are taken from special objects table.

 Function is called from TStreamerInfo WriteBuffer and Readbuffer functions
 and indent new level in data structure.
 This call indicates, that TStreamerInfo functions starts streaming
 object data of correspondent class

 Function is called from TStreamerInfo WriteBuffer and Readbuffer functions
 and decrease level in sql structure.

 Function is called from TStreamerInfo WriteBuffer and Readbuffer functions
 and add/verify next element in sql tables
 This calls allows separate data, correspondent to one class member, from another

 This method inform buffer data of which class now
 will be streamed. When reading, classversion should be specified
 as was read by TBuffer::ReadVersion() call

 ClassBegin(), ClassEnd() & ClassMemeber() should be used in
 custom class streamers to specify which kind of data are
 now streamed to/from buffer. That information is used to correctly
 convert class data to/from "normal" sql tables with meaningfull names
 and correct datatypes. Without that functions data from custom streamer
 will be saved as "raw" data in special _streamer_ table one value after another
 Such MUST be used when object is written with standard ROOT streaming
 procedure, but should be read back in custom streamer.
 For example, custom streamer of TNamed class may look like:

 Method indicates end of streaming of classdata in custom streamer.
 See ClassBegin() method for more details.

 Method indicates name and typename of class memeber,
 which should be now streamed in custom streamer
 Following combinations are supported:
 1. name = "ClassName", typeName = 0 or typename==ClassName
    This is a case, when data of parent class "ClassName" should be streamed.
    For instance, if class directly inherited from TObject, custom
    streamer should include following code:
    b.ClassMember("TObject");
    TObject::Streamer(b);
 2. Basic data type
      b.ClassMember("fInt","Int_t");
      b >> fInt;
 3. Array of basic data types
      b.ClassMember("fArr","Int_t", 5);
      b.ReadFastArray(fArr, 5);
 4. Object as data member
      b.ClassMemeber("fName","TString");
      fName.Streamer(b);
 5. Pointer on object as datamember
      b.ClassMemeber("fObj","TObject*");
      b.StreamObject(b);
 arrsize1 and arrsize2 arguments (when specified) indicate first and
 second dimension of array. Can be used for array of basic types.
 For more details see ClassBegin() method description.

 This function is a part of IncrementLevel method.
 Also used in StartClass method

 This function is a part of SetStreamerElementNumber method.
 It is introduced for reading of data for specified data memeber of class.
 Used also in ReadFastArray methods to resolve problem of compressed data,
 when several data memebers of the same basic type streamed with single ...FastArray call

 Same functionality as TBuffer::ReadFastArray(...) but
 instead of calling cl->Streamer(obj,buf) call here
 buf.StreamObject(obj, cl). In that case it is easy to understand where
 object data is started and finished
