Detailed Description

iterates through the IntVects of a Box

BoxIterator iterates through the IntVects of a box. The actual sqeuence of IntVects is implementation-specific. Typical usage:

Box b; ... BoxIterator bit (b); for (bit.begin(); bit.ok(); ++bit) { IntVect iv = bit(); (do operations involving iv) }

Constructor & Destructor Documentation

BoxIterator::BoxIterator ( )

Default constructor. This constructs an invalid iterator. The user must call define before using.

References m_boxHi, m_boxLo, m_current, IntVect::Unit, and IntVect::Zero.

BoxIterator::BoxIterator ( const Box a_bx)

Constructs a BoxIterator and associates it with a Box. Arguments: a_bx (not modified) the Box to iterate over.

References define().

BoxIterator::BoxIterator ( const BoxIterator a_iterIn)

Copy constructor. Arguments: a_iterIn (not modified) the BoxIterator to copy.

References m_boxHi, m_boxLo, and m_current.

BoxIterator::~BoxIterator ( )

Member Function Documentation

void BoxIterator::setBox ( const Box a_bx)
void BoxIterator::define ( const Box a_bx)

Associates a Box with this BoxIterator. Arguments: a_bx (not modified) the Box to iterate over.

Referenced by BoundaryIterator::begin(), BoxIterator(), BoundaryIterator::next(), and BoundaryIterator::nextBox().

void BoxIterator::begin ( )
void BoxIterator::reset ( )

Sets this BoxIterator to the first IntVect in its Box. The definition of the "first" IntVect is implementation-dependent.

References begin().

void BoxIterator::operator++ ( )

Modifies this BoxIterator to set it to the next location in its Box. The definition of the "next location" of a Box is implementation-dependent.

References next().

void BoxIterator::next ( )
const IntVect & BoxIterator::operator() ( ) const

Returns the value of the InVect for the current location of this BoxIterator.

References CH_assert, m_boxHi, m_boxLo, and m_current.

bool BoxIterator::ok ( )
unsigned long long BoxIterator::size ( ) const

References m_boxHi, and m_boxLo.

IntVect BoxIterator::at ( unsigned long long  pt) const

References m_boxHi, and m_boxLo.
