Overview

Multimap is a generalization of a map or associative array abstract data type in which more than one value may be associated with and returned for a given key.

Example

map = Multimap.new
map["a"] = 100
map["b"] = 200
map["a"] = 300
map["a"]                              # -> [100, 300]
map["b"]                              # -> [200]

def initialize_copy(original) #:nodoc:
  @hash = Hash.new(original.default.dup)
  original._internal_hash.each_pair do |key, container|
    @hash[key] = container.dup
  end
end

#store(key, value) ⇒ Object Also known as: []=

call-seq:

map[key] = value        => value
map.store(key, value)   => value

Associates the value given by value with the key given by key. Unlike a regular hash, multiple can be assoicated with the same value.

map = Multimap["a" => 100, "b" => 200]
map["a"] = 9
map["c"] = 4
map   #=> {"a" => [100, 9], "b" => [200], "c" => [4]}
