public class AssetLinkLocalServiceImpl
extends AssetLinkLocalServiceBaseImpl

This class implements the methods needed to handle AssetLinks, the entity that relates different assets in the portal. The basic information stored for every link includes both assets entry IDs, the userId, the link type and the link's weight.
