public final class Feed
extends EnvironmentBasedEntity<Feed.Blueprint,Feed.Update>

Feed is a source of data. It reports about resources and metrics it knows about (and can send the actual data to other Hawkular components like metrics).

Note that the feed does not have a dedicated blueprint type (i.e. data required to create a new feed in some context), because the only data needed to create a new feed is its ID, which can easily be modelled by a String.
