com.google.gdata.data.extensions.FeedLink<F>

Type Parameters:

F - Nested feed type.

All Implemented Interfaces:

Extension, ILink, Reference

Direct Known Subclasses:

DocumentListAclFeedLink, DocumentListRevisionFeedLink, PortfolioFeedLink, PositionFeedLink

public class FeedLink<F extends BaseFeed<?,?>>
extends Link

The FeedLink class defines the object model for a link entity that refers to a GData feed. The feed content may be included inline via child elements of the feed link or only included by reference.
