// Basic structures for Reve VSD concept. Design criteria:
24
//
25
// * provide basic cross-referencing functionality;
26
//
27
// * small memory/disk footprint (floats / count on compression in
28
// split mode);
29
//
30
// * simple usage from tree selections;
31
//
32
// * placement in TClonesArray (composites are TObject derived);
33
//
34
// * minimal member-naming (impossible to make everybody happy).

286

287
// 1) Filters can be applied at copy time so that only part of the
288
// data is copied over.
289
//
290
// 2) Once the data is extracted it can be used without experiment
291
// software. Thus, external service can provide this data and local
292
// client can be really thin.
293
//
294
// 3) Some pretty advanced visualization schemes/selections can be
295
// implemented in a general framework by providing data extractors
296
// only. This is also good for PR or VIP displays.
297
//
298
// 4) These classes can be extended by particular implementations. The
299
// container classes will use TClonesArray with user-specified element
300
// class.
301
302
// The common behaviour could be implemented entirely without usage of
303
// a common base classes, by just specifying names of members that
304
// retrieve specific data. This is fine as long as one only uses tree
305
// selections but becomes painful for extraction of data into local
306
// structures (could a) use interpreter but this is an overkill and
307
// would cause serious trouble for multi-threaded environment; b) use
308
// member offsets and data-types from the dictionary).
