Detailed Description

template<int DIM>
class SAMRAI::pdat::EdgeIterator< DIM >

Class EdgeIterator<DIM> is an iterator that provides methods for stepping through the index space associated with a edge centered box. The indices are enumerated in column-major (e.g., Fortran) order. The iterator should be used as follows:

hier::Box<DIM> box;
...
for (EdgeIterator<DIM> c(box, axis); c; c++) {
   // use index c of the box
}

Note that the edge iterator may not compile to efficient code, depending on your compiler. Many compilers are not smart enough to optimize the looping constructs and indexing operations.

Constructor & Destructor Documentation

EdgeIterator() [1/3]

template<int DIM>

SAMRAI::pdat::EdgeIterator< DIM >::EdgeIterator

(

)

Default constructor for the edge iterator. The iterator must be initialized before it can be used to iterate over a box.

EdgeIterator() [2/3]

template<int DIM>

SAMRAI::pdat::EdgeIterator< DIM >::EdgeIterator	(	const hier::Box< DIM > &	box,
		const int	axis
	)

Constructor for the edge iterator. The iterator will enumerate the indices in the argument box.

EdgeIterator() [3/3]

template<int DIM>

SAMRAI::pdat::EdgeIterator< DIM >::EdgeIterator

(

const EdgeIterator< DIM > &

iterator

)

Copy constructor for the edge iterator

~EdgeIterator()

template<int DIM>

SAMRAI::pdat::EdgeIterator< DIM >::~EdgeIterator

(

)

Destructor for the edge iterator.

Member Function Documentation

operator=()

template<int DIM>

EdgeIterator<DIM>& SAMRAI::pdat::EdgeIterator< DIM >::operator=

(

const EdgeIterator< DIM > &

iterator

)

Assignment operator for the edge iterator.

operator*()

template<int DIM>

const EdgeIndex<DIM>& SAMRAI::pdat::EdgeIterator< DIM >::operator*

(

)

const

Extract the edge index corresponding to the iterator position in the box.

operator()()

template<int DIM>

const EdgeIndex<DIM>& SAMRAI::pdat::EdgeIterator< DIM >::operator()

(

)

const

Extract the edge index corresponding to the iterator position in the box.

operator bool()

template<int DIM>

SAMRAI::pdat::EdgeIterator< DIM >::operator bool

(

)

const

Return true if the iterator points to a valid index within the box.

operator const void *()

template<int DIM>

SAMRAI::pdat::EdgeIterator< DIM >::operator const void *

(

)

const

Return a non-NULL if the iterator points to a valid index within the box.

operator!()

template<int DIM>

bool SAMRAI::pdat::EdgeIterator< DIM >::operator!

(

)

const

Return whether the iterator points to a valid index within the box. This operator mimics the !p operation applied to a pointer p.

operator++()

template<int DIM>

void SAMRAI::pdat::EdgeIterator< DIM >::operator++

(

int

)

Increment the iterator to point to the next index in the box.

operator==()

template<int DIM>

bool SAMRAI::pdat::EdgeIterator< DIM >::operator==

(

const EdgeIterator< DIM > &

iterator

)

const

Test two iterators for equality (same index value).

operator!=()

template<int DIM>

bool SAMRAI::pdat::EdgeIterator< DIM >::operator!=

(

const EdgeIterator< DIM > &

iterator

)

const

Test two iterators for inequality (different index values).
