datastructures (version 0.2.9)

hashmap-class: Hashmap class

Description

Implementation of a hashmap data structure, i.e. an unordered collection of key-value pairs: $$f: keys -> values.$$ Hashmaps only to store unique keys-value pairs. For a data structure where multiple identical keys can be stores see multimap. Inserting and accessing is amortized in O(1). hashmap wraps a C++ unordered_map using Rcpp modules. Also see '>bimap for mappings in both ways.

Arguments
