This class holds a map with the main entities and the associated DiscoInfoProvider. We are considering the host of the recipient JIDs as main entities. It's the DiscoInfoProvider responsibility to provide information about the JID's name together with any possible requested node.<p> <p/> For example, let's have in the entities map the following entries: "localhost" and "conference.localhost". Associated with each entry we have different DiscoInfoProviders. Now we receive a disco#info request for the following JID: "room@conference.localhost" which is a disco request for a MUC room. So IQDiscoInfoHandler will look for the DiscoInfoProvider associated with the JID's host which in this case is "conference.localhost". Once we have located the provider we will delegate to the provider the responsibility to provide the info specific to the JID's name which in this case is "room". Among the information that a room could provide we could find its identity and the features it supports (e.g. 'muc_passwordprotected', 'muc_unmoderated', etc.). Finally, after we have collected all the information provided by the provider we will add it to the reply. On the other hand, if no provider was found or the provider has no information for the requested name/node then a not-found error will be returned.<P><P><DL><DT><B>Author:</B></DT> <DD>Gaston
