Detailed Description

template<int dim>
class idealii::TimeIteratorCollection< dim >

A collection of slab iterators to simplify time marching.

The second type of spacetime objects like spacetime::Triangulation, spacetime::DoFHandler and spacetime::Vector are simply doubly linked lists of objects corresponding to a specific slab.

For forward or backward time marching these lists need to be traversed simultaneously. This class combines all iterator increments or decrements into a single function call.

Constructor & Destructor Documentation

TimeIteratorCollection()

template<int dim>

idealii::TimeIteratorCollection< dim >::TimeIteratorCollection

(

)

Default constructor.

Note

Any iterators have to be registered using one of the add_iterator functions.
