Detailed Description

template<class LocalOrdinal, class GlobalOrdinal = LocalOrdinal, class Node = Kokkos::DefaultNode::DefaultNodeType>
class Tpetra::Import< LocalOrdinal, GlobalOrdinal, Node >

This class builds an object containing information necesary for efficiently importing off-processor entries.

Import is used to construct a communication plan that can be called repeatedly by computational classes to efficiently import entries from other nodes. For example, an exporter is used when we start out with a multiple-ownership distribution, and we want to merge that into a uniquely-owned distribution.

This class currently has one constructor, taking two Map objects specifying the distributions of the distributed objects on which the Export class will operate.

This class is templated on LocalOrdinal and GlobalOrdinal. The GlobalOrdinal type, if omitted, defaults to the LocalOrdinal type.
