org.red5.server.api.IScope
The scope object. A statefull object shared between a group of clients connected to the same context path. Scopes are arranged in hierarchical way, so its possible for a scope to have a parent and children scopes. If a client connects to a scope then they are also connected to its parent scope. The scope object is used to access resources, shared object, streams, etc. That is, scope are general option for grouping things in application. The following are all names for scopes: application, room, place, lobby. @author The Red5 Project (red5@osflash.org) @author Luke Hubbard (luke@codegent.com)
