UE3:IQueryHandler (UT3)

Interface >> IQueryHandler

Package: 

WebAdmin

The query handler interface. The WebAdmin contains a collection of query handlers with handle most requests assigned to the WebAdmin application. During creating the query handler will receive a couple of set up calls: init(...) and registerMenuItems(...). The webadmin has to register all URLs it will handle (url without the webapp path prefix). It is also allowed to replace an existing menu item. When the WebAdmin is shut down the cleanup() method will be called. Use this to perform some clean up and to set all Actor references to none (in case the query handler extends Object).
