ValueIterator Class

For easy loops a Value Iterator behaves like a ValueI-poiter:

1. Bool-casts checks if there are values,
2. Poiter-reference yields Value
3. Increment moves to next Value

	
ValueIterator values(archive);
while (values)
{
	cout << *values << endl;
	sum += values->getDouble();
	++values;
}

(Implemented as "smart poiter" wrapper for ValueIteratorI iterface)

Interface

• Obtain new, empty ValueIterator suitable for given Archive

  ValueIterator(const class Archive &archive);
  ValueIterator(ValueIteratorI *iter);
  ValueIterator();
  

• Check if iterator is at valid position

  operator bool () const;
  

• Retrieve current ValueI

     const ValueI * operator -> () const;
  const ValueI & operator * () const;
  

• Move to next/prev Value

  ValueIterator & operator ++ ();
  ValueIterator & operator -- ();
  

• Number of "similar" values that can be read as one chunk in a block operation:

  size_t determineChunk(const osiTime &until);
  

• Sampling period for current values in secs.

  double getPeriod() const;
