Multimap class

Description

Implementation of a multimap data structure, i.e. an unordered collection of key-value pairs:

f: keys -> values.

Multimaps are able to store several identical keys. For a data structure which unique keys, see hashmap. Inserting and accessing is amortized in O(1). hashmap wraps a C++ unordered_multimap using Rcpp modules. Also see bimap for mappings in both ways.

Slots

C++ object representing a mapping
