= timedcache

* http://timedcache.rubyforge.org

== DESCRIPTION:

TimedCache implements a cache in which you can place objects
and specify a timeout value.

If you attempt to retrieve the object within the specified timeout
period, the object will be returned. If the timeout period has elapsed,
the TimedCache will return nil.

== FEATURES:

* Memory or file-based data stores available.
* Thread safety.

== SYNOPSIS:

  cache = TimedCache.new
  cache.put :my_object_key, "Expensive data", 10 #=> "Expensive data"
  
  cache.get :my_object_key #=> "Expensive data"
  cache[:my_object_key]    #=> "Expensive data"
  
  ... 10 seconds later:
  cache.get :my_object_key #=> nil

== INSTALL:

  sudo gem timedcache
