Detailed Description

template<typename Index>
struct lagrange::internal::InverseMapping< Index >

A simple struct representing the inverse of a 1-to-many mapping.

Target element i is mapped to source elements with index in the range from mapping.data[mapping.offsets[i]] to mapping.data[mapping.offsets[i+1]].

Template Parameters

Index

Mapping index type.

Todo

Write iterator helpers to facilitate iterating over mapped data.
