ValueIteratorI Class

Value iterator iterface to be implemented. The preferred API is ValueIterator.

Interface

• Virtuals to be implemented by derived classes:

  virtual bool isValid() const = 0;
  virtual const ValueI * getValue() const = 0;
  virtual bool next() = 0;
  virtual bool prev() = 0;
  

• Number of "similar" values that can be read as one chunk in a block operation. (This call might go away when a MemoryArchive & network request mechanism is implemented. Let me know if you depend on this call. The result might also not be perfect, e.g. a single 8000 chunk could be reported as two 4000-sized chunks etc.)

  virtual size_t determineChunk(const osiTime &until) = 0;
  

• Sampling period for current values in secs.

  virtual double getPeriod() const = 0;
