Cache which drops least used items to satisfy a user-defined criterion, e.g., total size or number of items. This can be used as the data store for Expiration Cache (http://yuilibrary.com/gallery/show/expiration-cache) to limit both key lifetime and total memory.

Example of creating different types of MRU caches.

Code Sample

<script src="http://yui.yahooapis.com/3.5.1/build/yui/yui-min.js"></script>

YUI({
    //Last Gallery Build of this module
    gallery: 'gallery-2012.05.23-19-56'
}).use('gallery-mru-cache', function(Y)
{
	// create a cache which holds up to 500M
	var size_cache = new Y.MRUCache(
	{
		metric: function(value)
		{
			return value.length;
		},
		limit: Math.pow(2, 29) // 500M
	});
 
	size_cache.put('foo', 'bar');
	var data = size_cache.get('foo');
 
	// create a cache which holds up to 1000 items
	var count_cache = new Y.MRUCache(
	{
		metric: function(value)
		{
			return +1;
		},
		limit: 1000
	});
});
