Detailed Description

template<class T_Iter, class T_IterCat, class T_Indice, class T_ValRef, class T_Diff>
class AbstractLinAlgPack::TransSparseCOOElementViewIter< T_Iter, T_IterCat, T_Indice, T_ValRef, T_Diff >

Templateded iterator for iterating through a set of COO Matix elements but viewing them in transpose.

The iterator type T_Iter must yield a type that conforms to the SparseCOOElementTemplateInterface specification. In particular it must support itr->value(), itr->row_i(), and itr->col_i().

Any category of iterator can be used with this class. The relavant iterator traits have to be added to the template list since MS VC++ 5.0 does not support partial template specialization and therefore std::iterator_traits<> does not exist.

There is a lot of code here but for an iterator object, only the underlying iterator is stored. Thus, because of inlining accessing a COO matrix through this transposed iterator is just as efficient as assessing it through its non-transposed iterator. This is important for efficiency reasons.

The default assignment operator and copy constructor are allowed.

The template arguments are:{itemize} T_Iter The type of the iterator that is used to yield COO sparse elements T_IterCat The category of iterator (forward, random access etc.) T_Indice The type returned by itr->indice() T_ValRef The type for the value returned by value(). For example, if T_Ele is a const type then T_ValRef should be a constant reference and if it is a non-const type it should be a non-const reference.
