public interface IUpdatableSource

An updatable source is a class implementing one of the I*Source interfaces, which needs to be updated to refresh its data. Typically an data source which retrieves data from other source keeps them into a cache and refreshes the cache when the consumer needs a new refresh.
A CrossSection, for instance, is an updatable source, since it collects data from a collection. Accessing its source interface, the consumer can obtain the lastest cached data, but if it want updated ones it has to invoke the updateSource() method of the CrossSection.
Each statistical object contained in the jas.statistics package automatically refreshes the IUpdatableSource source before retrieving the latest data.
