Public Member Functions | |
| UPennWalkControllerBehavior () | |
| constructor | |
| virtual | ~UPennWalkControllerBehavior () |
| destructor | |
| virtual void | DoStart () |
| By default, merely adds to the reference counter (through AddReference()); Note you should still call this from your overriding methods. | |
| virtual void | DoStop () |
By default, subtracts from the reference counter (RemoveReference()), and thus may deletex if zero; Don't forget to still call this when you override this; Warning: call this at the end of your DoStop(), not beginning (it might delete this ). | |
| virtual UPennWalkMC * | getWalkMC () |
| returns the WalkMC which [will be|is being] used | |
| virtual MotionManager::MC_ID | getWalkID () |
| returns the current Walk's MotionCommand ID | |
| virtual void | processEvent (const EventBase &) |
| The only event we could possibly receive is the stop-if-no-heartbeat timer. | |
| virtual std::string | getDescription () const |
| Gives a short description of what this particular instantiation does (in case a more specific description is needed on an individual basis). | |
Static Public Member Functions | |
| static int | mechacmd_callback (char *buf, int bytes) |
| called by wireless when there's new data | |
| static std::string | getClassDescription () |
| Gives a short description of what this class of behaviors does... you should override this (but don't have to). | |

Member Function Documentation
| static std::string UPennWalkControllerBehavior::getClassDescription | ( | ) | [inline, static] |
Gives a short description of what this class of behaviors does... you should override this (but don't have to).
If you do override this, also consider overriding getDescription() to return it
Reimplemented from BehaviorBase.

| virtual std::string UPennWalkControllerBehavior::getDescription | ( | ) | const [inline, virtual] |
Gives a short description of what this particular instantiation does (in case a more specific description is needed on an individual basis).
By default simply returns getName(), because any calls from a BehaviorBase function to getClassDescription() are going to call BehaviorBase::getClassDescription(), not ~YourSubClass~getClassDescription(), because static functions can't be virtual in C++ (doh!)
This means that getDescription called on a pointer to a BehaviorBase of unknown subtype would always return an empty string, which is pretty useless. So instead we return the name in this situation. If you want getDescription to return getClassDescription, you'll have to override it in your subclass to do so.

Member Data Documentation
The last WCB object that was theOne, so we can restore it to prominence when we die. This is a nice gesture, but it doesn't really make sense since we're all using the same port. But just in case something changes and we don't do that, this mechanism is in place.

UPennWalkControllerBehavior * UPennWalkControllerBehavior::theOne = NULL [static] |
Points to the one UPennWalkControllerBehavior object that the input command stream is talking to. A kludge. Dunno how you're gonna make sure you're not using this uninitialized.
