Public Member Functions

WalkControllerBehavior ()

constructor

virtual ~WalkControllerBehavior ()

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 WalkMC * 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 getName () const

Identifies the behavior in menus and such.

Static Public Member Functions

int mechacmd_callback (char *buf, int bytes)

called by wireless when there's new data

std::string getClassDescription ()

Gives a short description of what this class of behaviors does... you should override this (but don't have to).

WalkControllerBehavior* WalkControllerBehavior::theLastOne [private]

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.

WalkControllerBehavior * WalkControllerBehavior::theOne = NULL [static]

Points to the one WalkControllerBehavior object that the input command stream is talking to. A kludge. Dunno how you're gonna make sure you're not using this uninitialized.
