Commands are added to the shell either at startup (CCI DAT commands, above) or by the user with addCommand. All CCI DAT and user defined commands are based on the Command class defined in rce/shell/Command.hh. The public interface to Command is:
...
| Code Block |
|---|
#include "rce/shell/Command.hh"
namespace FOO {
using RCE::Shell::Command;
class NewCommand : public Command {
public:
NewCommand();
virtual ~NewCommand() {}
virtual std::string usage();
virtual MainFunc main();
};
int NewCommand_main(int argc, char** argv) {
printf("This is a test of the new command\n");
return 0;
}
NewCommand::NewCommand() : Command("newCommand", "misc") {}
std::string NewCommand::usage() {
static std::string u = " newCommand # Do nothing but print a message\n";
return u;
}
Command::MainFunc NewCommand::main() {
return NewCommand_main;
}
}
