  $Log: DataSourceFixedBuf.h,v $
  Revision 1.1  1996/08/04 21:23:24  beyer
  DataSource's are now reference counted.
  Added Version() which TData now check to see if the DataSource has changed,
    and if it has, it rebuilds its index and invalidates the cache.
  DataSourceFixedBuf is a DataSourceBuf that allocates and destoyes its
    own buffer.
  DerivedDataSource functionality is now in the TData constructor.
  Added some defaults for virtual methods.
