Interface IAliasCache

All Superinterfaces:

ICache, IComponent, IDBCache, IInitializable

public interface IAliasCache
extends IDBCache

The Alias key class manages the various aliases There are three main concepts in aliases: 1) Source is the key identifier That's what this represents. This can be either an IURI or a string 2) Target is the value. This can be either an IURI|IThingID or a string 3) Params are the optional name value pairs to append to the target
