virtual bool IsFinished ()
 Returns whether this command is finished. More...
 
virtual void End ()
 Called when the command ended peacefully. More...
 
virtual void Interrupted ()

Member Function Documentation

void PrintCommand::End ( )
protectedvirtual

Called when the command ended peacefully.

This is where you may want to wrap up loose ends, like shutting off a motor that was being used in the command.

Implements Command.

void PrintCommand::Interrupted ( )
protectedvirtual

Called when the command ends because somebody called cancel() or another command shared the same requirements as this one, and booted it out.

This is where you may want to wrap up loose ends, like shutting off a motor that was being used in the command.

Generally, it is useful to simply call the end() method within this method

Implements Command.

bool PrintCommand::IsFinished ( )
protectedvirtual

Returns whether this command is finished.

If it is, then the command will be removed and end() will be called.

It may be useful for a team to reference the isTimedOut() method for time-sensitive commands.

Returns
whether this command is finished.

Command::isTimedOut() isTimedOut()

Implements Command.
