TSqlBufRIterator Class Reference
TSqlBufRIterator iterator gives read-only access to the flat buffer content (RSqlBufFlat class). For convenience TSqlBufRIterator can represent the flat buffer fields content as one of the basic SQL types: TInt, TInt64, TReal, 16-bit text, 8-bit binary block. The text and binary fields may be accessed also as a byte stream.
