Detailed Description

Class to manage box-shifting used to enforce periodic BC's.

The ShiftIterator class contains a list of shift vectors necessary to enforce periodic boundary conditions (enforced by shifting the Box of each Fab, then copying any overlapping valid cells with ghost cells of the shifted Fab. Depending on the number of periodic directions, the list of shift vectors over which to iterate differs.

Constructor & Destructor Documentation

ShiftIterator::ShiftIterator (    )  [inline]

Basic constructor.

ShiftIterator::ShiftIterator (  const bool *    a_isPeriodic )

Defining Constructor. Builds a ShiftIterator based on the periodicity in a_isPeriodic

ShiftIterator::ShiftIterator (  const ShiftIterator &    a_shiftIt )  [inline]

Copy constructor.

ShiftIterator::~ShiftIterator (    )

Destructor.

---

Member Function Documentation

void ShiftIterator::begin (    )  [inline]

Equivalent to reset().

void ShiftIterator::computeShifts (  const bool *    a_isPeriodic )

Recompute shift vectors based on periodic directions.

void ShiftIterator::end (    )  [inline]

Skip the iterator to the end. ok() will return false after this method is called.

IntVect ShiftIterator::i (    )  const [inline]

Equivalent to the () operator.

void ShiftIterator::incr (    )  [inline]

Equivalent to the ++ operator.

bool ShiftIterator::ok (    )  const [inline]

Is the iterator still within its range of shift vectors?

IntVect ShiftIterator::operator() (    )  const [inline]

Returns the current shift unit vector.

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

Increment to the next shift unit vector.

ShiftIterator & ShiftIterator::operator= (  const ShiftIterator &    a_src )  [inline]

Assignment operator.

void ShiftIterator::reset (    )  [inline]

Reset to first shift unit vector.
