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 UPennWalkMCgetWalkMC ()
 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).

void UPennWalkControllerBehavior::DoStart (  )  [virtual]

By default, merely adds to the reference counter (through AddReference()); Note you should still call this from your overriding methods.

Reimplemented from BehaviorBase.

void UPennWalkControllerBehavior::DoStop (  )  [virtual]

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 ).

Reimplemented from BehaviorBase.

virtual UPennWalkMC* UPennWalkControllerBehavior::getWalkMC (  )  [inline, virtual]

returns the WalkMC which [will be|is being] used

virtual void UPennWalkControllerBehavior::processEvent ( const EventBase  )  [inline, virtual]

The only event we could possibly receive is the stop-if-no-heartbeat timer.

Reimplemented from BehaviorBase.

Definition at line 86 of file UPennWalkControllerBehavior.h.

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.

Definition at line 91 of file UPennWalkControllerBehavior.h.

Referenced by getDescription().

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.

Reimplemented from BehaviorBase.

Definition at line 96 of file UPennWalkControllerBehavior.h.


Member Data Documentation

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.

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.
