TROInterfaceRegistry

Overview

This is a collection to store and manage a list of interface references. In addition to existing ancestor's functionality this class provides a couple of methods to keep interface references unique in the list (TInterfaceList allows to store several copies of the same reference in the list).
This is the rarely used class, inside the library it is used only by TROBroadcastChannel internally. Also can be used by users if uniquity of stored interface references is required.
