Detailed Description

Iterator for an IntVectSet.

IVSIterator iterates over every point (IntVect) in an IntVectSet. It has exactly the same syntax and sematic as BoxIterator. Typical usage:

   IntVectSet ivs;
   ...
   IVSIterator ivsit (ivs);
   for (ivsit.begin(); ivsit.ok(); ++ivsit)
   {
     IntVect iv = ivsit();
     (do operations involving iv)
   }

Constructor & Destructor Documentation

IVSIterator::IVSIterator (    )  [inline]

A default constructed iterator iterates over an empty IntVectSet. It starts in the begin() state, and is never ok().

IVSIterator::IVSIterator (  const IntVectSet &    ivs )

Iterates over IntVectSet ivs. There is no canonical ordering. Starts in the begin() state.

IVSIterator::~IVSIterator (    )  [inline]

Member Function Documentation

void IVSIterator::begin (    )  [inline]

initialize this iterator to the first IntVect in its IntVectSet

void IVSIterator::define (  const IntVectSet &    ivs )

Modifies this IVSIterator to iterate over the IntVectSet ivs. There is no canonical ordering. Starts in the begin() state.

void IVSIterator::end (    )  [inline]

move this iterator to after the last IntVect in the set The iterator will be !ok() afterwards.

void IVSIterator::incr (    )  [inline]

same as operator++

const IntVect& IVSIterator::iv (    )  const [inline]

same as operator()

bool IVSIterator::ok (    )  const [inline]

returns true if this iterator is still in its IntVectSet

const IntVect & IVSIterator::operator() (    )  const [inline]

returns the IntVect that this iterator is at

void IVSIterator::operator++ (    )  [inline]

move iterator to the next IntVect in its IntVectSet

void IVSIterator::reset (    )  [inline]

same as begin()
