ExpandingValueIteratorI Class

A ValueIteratorI that expands "repeated" values into multiple values. (Repeated values have a severity of ARCH_REPEAT, the status is then interpreted as a repetition count).
Clients using this filter will never see repeat counts but always the expanded values.

Example Usage

The expanding iterator requires a "base" iterator for the archive type that you work on:

ValueIterator   base(archive);
channel->getValueAfterTime(start, base );

When creating an ExpandingValueIteratorI for that base iterator, it's usually convenient to access it via a ValueIterator smart wrapper so that it behaves like an ordinary iterator:

ValueIterator value (new ExpandingValueIteratorI(base));
while (value)
{
	cout << *value << "\n";
	++value;
}

TO DO:
Huge repeat counts are expanded. This takes forever and the repeats may not be useful.

Interface

• Create an ExpandingValueIteratorI based on another ValueIterator.
  The base iterator has to exist for the lifetime of the ExpandingValueIterator.

  ExpandingValueIteratorI(ValueIterator &base);
  

• Implemented of ValueIteratorI:

  bool isValid() const;
  const ValueI * getValue() const;
  bool next();
  bool prev();
  size_t determineChunk(const osiTime &until);
  double getPeriod() const;     
  

• Is current value generated by expanding repeated values?

  bool isExpanded() const;
