Examples of FeedProvider

gov.nasa.arc.mct.components.FeedProvider
This interface provides a time based feed. This standardizes the connection between views and the feed providers, so that visualizations such as plots and tables can be provided without direct knowledge of the feed mechanism (this will handle ISP and other standard based feeds such as ATOM). The rendering mechanism will handle subscriptions for feeds based on the id (see {@link #getSubscriptionId()}). FeedProvider instances must be available from {@link gov.nasa.arc.mct.components.AbstractComponent#getCapability(Class)}.
