Detailed Description

An iterator that only returns usable members of the SpatialCell.

Definition at line 159 of file SpatialCell.h.

Constructor & Destructor Documentation

SpatialCellCandidateIterator() [1/2]

lsst::afw::math::SpatialCellCandidateIterator::SpatialCellCandidateIterator ( CandidateList::iterator  iterator, CandidateList::iterator  end, bool  ignoreBad  )

protected

ctor; designed to be used to pass begin to SpatialCellCandidateIterator

Parameters

iterator	Where this iterator should start
end	One-past-the-end of iterator's range
ignoreBad	Should we pass over bad Candidates?

Definition at line 240 of file SpatialCell.cc.

        : _iterator(iterator), _end(end), _ignoreBad(ignoreBad) {
    for (; _iterator != _end; ++_iterator) {
        (*_iterator)->instantiate();
 
        if (!(_ignoreBad && (*_iterator)->isBad())) {  // found a good candidate, or don't care
            return;
        }
    }
}

SpatialCellCandidateIterator() [2/2]

lsst::afw::math::SpatialCellCandidateIterator::SpatialCellCandidateIterator ( CandidateList::iterator  iterator, CandidateList::iterator  end, bool  ignoreBad, bool    )

protected

ctor; designed to be used to pass end to SpatialCellCandidateIterator

Parameters

iterator	start of of iterator's range; not used
end	Where this iterator should start
ignoreBad	Should we pass over bad Candidates?

Definition at line 252 of file SpatialCell.cc.

        : _iterator(end), _end(end), _ignoreBad(ignoreBad) {
    if (ignoreBad) {
        // We could decrement end if there are bad Candidates at the end of the list, but it's probably
        // not worth the trouble
    }
}

operator++()

void lsst::afw::math::SpatialCellCandidateIterator::operator++

(

)
