A simple Ruby implementation of a Circular Buffer
Latest commit 0c0baa1 Oct 18, 2013 @chrisn chrisn Apache 2.0 license



A circular buffer, cyclic buffer or ring buffer is a data structure that uses a single, fixed-size buffer as if it were connected end-to-end. This structure lends itself easily to buffering data streams. This library impliments such a buffer.


gem install cbuffer

** Usage

require 'cbuffer'

a = 5 => <CBuffer @size=5> 
a.put 1 => false 
a.put 2 => false 
a.put "Duncan" => false 
a.put 999 => false 
a.get => 1 
a.get => 2 
a.get => "Duncan" 
a.put "xxx" => false 
a.get => 999
