// Overview: CMICmdCmdGdbShow interface.
//
// To implement new MI commands, derive a new command class from
// the command base
// class. To enable the new command for interpretation add the new
// command class
// to the command factory. The files of relevance are:
// MICmdCommands.cpp
// MICmdBase.h / .cpp
// MICmdCmd.h / .cpp
// For an introduction to adding a new command see
// CMICmdCmdSupportInfoMiCmdQuery
// command class as an example.
#pragma once
// In-house headers:
#include "MICmdBase.h"
//++
//============================================================================
// Details: MI command class. MI commands derived from the command base class.
// *this class implements MI command "gdb-show".
// This command does not follow the MI documentation exactly. While
// *this
// command is implemented it does not do anything with the gdb-set
// variable past in.
// 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.
