|
// Details: MI command class. MI commands derived from the command base class.
|
|
// *this class implements GDB command "info".
|
|
// The design of matching the info request to a request action (or
|
|
// command) is very simple. The request function which carries out
|
|
// the task of information gathering and printing to stdout is part of
|
|
// *this class. Should the request function become more complicated
|
|
// then
|
|
// that request should really reside in a command type class. Then this
|
|
// class instantiates a request info command for a matching request.
|
|
// The
|
|
// design/code of *this class then does not then become bloated. Use a
|
|
// lightweight version of the current MI command system.
