rufus-lru
LruHash class, a Hash with a max size, controlled by a LRU mechanism
getting it
gem install rufus-lru
or at
rubyforge.org/frs/?group_id=4812
usage
It’s a regular hash, but you have to set a maxsize at instantiation.
Once the maxsize is reached, the hash will discard the element that was the least recently used (hence LRU).
require 'rubygems'
require 'rufus/lru'
h = LruHash.new 3
5.times { |i| h[i] = "a" * i }
puts h.inspect # >> {2=>"aa", 3=>"aaa", 4=>"aaaa"}
h[:newer] = "b"
puts h.inspect # >> {:newer=>"b", 3=>"aaa", 4=>"aaaa"}
dependencies
None.
