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() [1/2]

IVSIterator::IVSIterator ( )

inline

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

References IntVectSet::IVSIterator.

IVSIterator() [2/2]

IVSIterator::IVSIterator

(

const IntVectSet &

ivs

)

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

~IVSIterator()

IVSIterator::~IVSIterator ( )

inline

References IntVectSet::define().

Member Function Documentation

define()

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.

operator()()

const IntVect & IVSIterator::operator() ( ) const

inline

returns the IntVect that this iterator is at

References IntVectSet::m_dense, and IntVectSet::m_isdense.

iv()

const IntVect& IVSIterator::iv ( ) const

inline

same as operator()

Referenced by IntVectSet::copy(), and IntVectSet::minus_intvect().

ok()

bool IVSIterator::ok ( ) const

inline

returns true if this iterator is still in its IntVectSet

References IntVectSet::m_dense, and IntVectSet::m_isdense.

operator++()

void IVSIterator::operator++ ( )

inline

move iterator to the next IntVect in its IntVectSet

References IntVectSet::m_dense, and IntVectSet::m_isdense.

incr()

void IVSIterator::incr ( )

inline

same as operator++

begin()

void IVSIterator::begin ( )

inline

initialize this iterator to the first IntVect in its IntVectSet

References IntVectSet::m_dense, and IntVectSet::m_isdense.

reset()

void IVSIterator::reset ( )

inline

same as begin()

Referenced by IVSFAB< T >::define(), MiniIVFAB< Real >::define(), and BaseIVFAB< Real >::define().

end()

void IVSIterator::end ( )

inline

move this iterator to after the last IntVect in the set

The iterator will be !ok() afterwards.
