DataSource Utility: DataSource with Caching

Use the plug() method to initialize the DataSourceJSONSchema plugin and pass in the configuration value max to set the maximum size.

YUI().use("datasource-get", "datasource-jsonschema", "datasource-cache", function(Y) {
    var source = "remote source",
        myDataSource = new Y.DataSource.Get({source:"http://query.yahooapis.com/v1/public/yql?format=json&"}),
        callback = {
            success: function(e){
                alert(e.response);
            },
            failure: function(e){
                alert("Could not retrieve data: " + e.error.message);
            }
        };

myDataSource.plug({fn: Y.Plugin.DataSourceJSONSchema, cfg: {
        schema: {
            resultListLocator: "query.results.result",
            resultFields: ["title"]
        }
    }});

myDataSource.plug({fn:Y.Plugin.DataSourceCache, cfg:{max:3}});

// Adds to cache
    myDataSource.sendRequest("q=select%20*%20from%20search.web%20where%20query%3D%22foo%22",callback);
    // Adds to cache
    myDataSource.sendRequest("q=select%20*%20from%20search.web%20where%20query%3D%22bar%22",callback);
    // Retrieves from cache
    myDataSource.sendRequest("q=select%20*%20from%20search.web%20where%20query%3D%22foo%22",callback);
});
