Detailed Description
template<class G, class T>
class Dune::Amg::SubGraph< G, T >::VertexIterator
class Dune::Amg::SubGraph< G, T >::VertexIterator
The vertex iterator of the graph.
Member Typedef Documentation
◆ DerivedType
|
inherited |
The type of derived iterator.
The iterator has to define following functions have to be present:
// Access the value referred to.
// Compare for equality with iterator j
bool equals(j);
// position the iterator at the next element.
void increment()
// check for equality with other iterator
bool equals(other)
bool equals(const VertexIterator &other) const
Equality iterator.
const VertexDescriptor & dereference() const
Get the descriptor of the current vertex.
const VertexDescriptor & Reference
The type of the reference to the values accessed.

Constructor & Destructor Documentation
◆ VertexIterator() [1/2]
template<class G , class T >
|
explicit |
Constructor.
- Parameters
-
graph The graph over whose vertices to iterate. current The position of the iterator. end The last vertex of the graph.
◆ VertexIterator() [2/2]
template<class G , class T >
|
explicit |
Constructor for end iterator.
Use with care! All operations except operator== or operator!= will fail!
- Parameters
-
current The position of the iterator.
Member Function Documentation
◆ begin()
template<class G , class T >
EdgeIterator Dune::Amg::SubGraph< G, T >::VertexIterator::begin | ( | ) | const |
Get an iterator over all edges starting at the current vertex.
- Returns
- Iterator position on the first edge to another vertex.
◆ dereference()
template<class G , class T >
const VertexDescriptor & Dune::Amg::SubGraph< G, T >::VertexIterator::dereference | ( | ) | const |
Get the descriptor of the current vertex.
- Returns
- The index of the currently referenced vertex.
◆ end()
template<class G , class T >
EdgeIterator Dune::Amg::SubGraph< G, T >::VertexIterator::end | ( | ) | const |
Get an iterator over all edges starting at the current vertex.
- Returns
- Iterator position on the first edge to another vertex.
