To demonstrate how object overloading works with Agar objects in Ada, .Nm registers a new Agar object class written in pure Ada called "Animal" (see .Pa animal.adb ) . It then creates an instance of the "Animal" class and names it "Cow". It registers an event handler for an event called .Sq some-event and triggers it. This illustrates how message passing works in Agar (i.e., Agar event handlers are passed multiple typed arguments which can be accessed by index, by name, or by popping off the stack). .Pp The program then demonstrates the use of .Fn Agar.Object.Get_Name , which converts the name of an .Xr AG_Object 3 to an Ada string. .Pp Serialization is demonstrated by .Nm when it saves the test "Cow" object to a file called .Pa Cow.obj . .Sh ENVIRONMENT .Bl -tag -width "LANG " .It Dv LANG ISO language code determining which translation should be used. .El .\" .Sh FILES .Sh SEE ALSO .Xr AG_Intro 3 , .Xr AG_Error 3 , .Xr AG_Event 3 , .Xr AG_DataSource 3 , .Xr AG_Object 3 , .Xr agar_ada_demo 1
