TBufferSQL2 Class Reference

Converts data to SQL statements or read data from SQL tables.

Class for serializing/deserializing object to/from SQL data base. It redefines most of TBuffer class function to convert simple types, array of simple types and objects to/from TSQLStructure objects. TBufferSQL2 class uses streaming mechanism, provided by ROOT system, therefore most of ROOT and user classes can be stored. There are limitations for complex objects like TTree, TClonesArray, TDirectory and few other, which can not be converted to SQL (yet).

Member Function Documentation

ClassBegin()

void TBufferSQL2::ClassBegin ( const TClass *  cl, Version_t  classversion = -1  )

finalvirtual

This method inform buffer data of which class now will be streamed.

When reading, classversion should be specified as was read by TBuffer::ReadVersion().

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:
