This update has little 00019 * effect on the interface (only 1 method has been changed in the interface). 00020 * Code also preserves backwards compatibility so that old versions of 00021 * StDbLib can read new table structures. 00022 * -Important features: 00023 * a. more efficient low-level table structure (see StDbSql.cc) 00024 * b. more flexible indexing for new systems (see StDbElememtIndex.cc) 00025 * c. environment variable override KEYS for each database 00026 * d. StMessage support & clock-time logging diagnostics 00027 * -Cosmetic features 00028 * e. hid stl behind interfaces (see new *Impl.* files) to again allow rootcint access 00029 * f. removed codes that have been obsolete for awhile (e.g. db factories) 00030 * & renamed some classes for clarity (e.g. tableQuery became StDataBaseI 00031 * and mysqlAccessor became StDbSql) 00032 * 00033 * Revision 1.5 2000/03/28 17:03:18 porter 00034 * Several upgrades: 00035 * 1. configuration by timestamp for Conditions 00036 * 2. query by whereClause made more systematic 00037 * 3. conflict between db-stored comments & number lists resolved 00038 * 4. ensure endtime is correct for certain query falures 00039 * 5. dbstl.h->handles ObjectSpace & RogueWave difference (Online vs Offline) 00040 * 00041 * Revision 1.4 1999/12/29 13:49:34 porter 00042 * fix for Solaris-CC4.2 within StRoot make (cons)... 00043 * replaced #include <config.h> with #include <ospace/config.h> 00044 * 00045 * Revision 1.3 1999/12/28 21:31:41 porter 00046 * added 'using std::vector' and 'using std::list' for Solaris CC5 compilation. 00047 * Also fixed some warnings arising from the CC5 compiles 00048 * 00049 * Revision 1.2 1999/09/30 02:06:01 porter 00050 * add StDbTime to better handle timestamps, modify SQL content (mysqlAccessor) 00051 * allow multiple rows (StDbTable), & Added the comment sections at top of 00052 * each header and src file 00053 * 00054 **************************************************************************/ 00055 #ifndef STDBBUFFERI_H 00056 #define STDBBUFFERI_H 00057 00058 class StDbBufferI { 00059 00060 public: 00061 00062 virtual ~StDbBufferI(){};
