Nonvirtual member functions

• void check_and_create_text(void) - when called, this routine will create the text equivalent of the command, if necessary (that is, when the command HAS a text equiv and the string has not yet been created). This will be done by calling the virtual function create_text().
• int execute(void) - execute the command; this will call the virtual function do_execute(), and return whether the action was successful.
• int has_text(void) - return whether or not the command has a text equivalent (if not, the text equivalent is an empty string).
• char *text(void) - return the text equivalent. This will call the routines to create the string if necessary.
• Cmdtype gettype(void) - return the type code for this object.
• int getUIid(void) - return the ID number of the UIObject which created this Command instance.
• friend ostream& operator<< - an overload of the << operator to allow a Command to be easily printed to an ostream.
• friend Inform& operator<< - the same, to send the text equivalent of the Command to an inform object. For example: Command *cmd = new CmdAck(); msgInfo << *cmd;
