template<class T, class A = std::allocator<RemoteIndex<typename T::GlobalIndex, typename T::LocalIndex::Attribute> >>
class Dune::RemoteIndices< T, A >
The indices present on remote processes.
To set up communication between the set of processes active in the communication every process needs to know which indices are also known to other processes and which attributes are attached to them on the remote side.
This information is managed by this class. The information can either be computed automatically calling rebuild (which requires information to be sent in a ring) or set up by hand using the RemoteIndexListModifiers returned by function getModifier(int).
- Template Parameters
-
T | The type of the underlying index set. |
A | The type of the allocator to use. |
