Detailed Description

iterates through the IntVects on the surface of a Box

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

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

Constructor & Destructor Documentation

BoundaryIterator::BoundaryIterator

(

)

[inline]

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

References CH_SPACEDIM, and m_sdir.

BoundaryIterator::BoundaryIterator

(

const Box &

a_bx

)

[inline]

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

References define().

BoundaryIterator::~BoundaryIterator

(

)

[inline]

Member Function Documentation

void BoundaryIterator::setBox

(

const Box &

a_bx

)

void BoundaryIterator::define

(

const Box &

a_bx

)

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

Referenced by BoundaryIterator().

void BoundaryIterator::begin

(

)

[inline]

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

References BoxIterator::define(), m_box, m_current, and m_sdir.

Referenced by reset().

void BoundaryIterator::reset

(

)

[inline]

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

References begin().

void BoundaryIterator::operator++

(

)

[inline]

Modifies this BoundaryIterator 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 BoundaryIterator::next

(

)

[inline]

References BoxIterator::begin(), CH_SPACEDIM, BoxIterator::define(), m_box, m_current, m_sdir, BoxIterator::next(), and BoxIterator::ok().

Referenced by operator++().

const IntVect & BoundaryIterator::operator()

(

)

const [inline]

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

References m_current.

bool BoundaryIterator::ok

(

)

const [inline]

Returns true if this BoundaryIterator's location is within its Box.

References CH_SPACEDIM, and m_sdir.

Referenced by box(), and nextBox().

const Box & BoundaryIterator::box

(

)

const [inline]

Can request the current boundary box that this iterator is working on

References CH_assert, m_box, m_sdir, and ok().

void BoundaryIterator::nextBox

(

)

[inline]

skip to the next boundary box in this iterator

References BoxIterator::define(), m_box, m_current, m_sdir, and ok().
