38 //! Defines the general frame for working with a SessionPilot.
39 //! Each Activator treats a set of Commands. Commands are given as
40 //! alphanumeric strings. They can be of two main forms :
41 //! - classic, to list, evaluate, enrich the session (by itself) :
42 //! no specific remark, its complete execution must be described
43 //! - creation of a new item : instead of creatinf it plus adding
44 //! it to the session (which is a classic way), it is possible
45 //! to create it and make it recorded by the SessionPilot :
46 //! then, the Pilot will add it to the session; this way allows
47 //! the Pilot to manage itself named items
49 //! In order to make easier the use of Activator, this class
50 //! provides a simple way to Select an Actor for a Command :
51 //! each sub-class of SectionActor defines the command titles it
52 //! recognizes, plus attaches a Number, unique for this sub-class,
53 //! to each distinct command title.
55 //! Each time an action is required, the corresponding Number
56 //! can then be given to help the selection of the action to do.
