Detailed Description
Base class for camera streaming communication classes, handles upstream communication.This class isn't meant to be run directly -- it just provides common functionality for its subclasses.

Public Member Functions | |
| virtual void | processEvent (const EventBase &e) |
| By defining here, allows you to get away with not supplying a processEvent() function for the EventListener interface. By default, does nothing. | |
| 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). | |
| int | receiveData (char *data, unsigned int len) |
| called when new data is available (currently, only to toggle sensor sending) | |
| void | sendSensors () |
| causes current sensor values to be sent through curSocket (along with video data) | |
Static Public Member Functions | |
| static std::string | getClassDescription () |
| Gives a short description of what this class of behaviors does... you should override this (but don't have to). | |
Protected Member Functions | |
| CameraStreamBehavior (const std::string &name, Socket *&s) | |
| constructor, protected because you're not intended to instantiate this directly | |
| CameraStreamBehavior (const std::string &classname, const std::string &name, Socket *&s) | |
| constructor, protected because you're not intended to instantiate this directly | |
Protected Attributes | |
| Socket *& | curSocket |
| the socket over which to send updates | |
| unsigned int | sensorListeners |
| number of times startSensors has been sent, minus number of times stopSensors has been sent | |
| unsigned int | lastProcessedTime |
| timestamp of last sensor update sent | |
Private Member Functions | |
| CameraStreamBehavior (const CameraStreamBehavior &) | |
| don't call (copy constructor) | |
| CameraStreamBehavior & | operator= (const CameraStreamBehavior &) |
| don't call (assignment operator) | |
Constructor & Destructor Documentation
| CameraStreamBehavior::CameraStreamBehavior | ( | const std::string & | name, | |
| Socket *& | s | |||
| ) | [inline, protected] |
constructor, protected because you're not intended to instantiate this directly
- Parameters:
-
name the name of the instance and the class s the subclass's socket, a reference is stored so CameraStreamBehavior will always have access to the current socket
Definition at line 27 of file CameraStreamBehavior.h.
| CameraStreamBehavior::CameraStreamBehavior | ( | const std::string & | classname, | |
| const std::string & | name, | |||
| Socket *& | s | |||
| ) | [inline, protected] |
constructor, protected because you're not intended to instantiate this directly
- Parameters:
-
classname the name of the class type name the name of the instance s the subclass's socket, a reference is stored so CameraStreamBehavior will always have access to the current socket

Member Function Documentation
| static std::string CameraStreamBehavior::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.
Reimplemented in RawCamBehavior, and SegCamBehavior.

Referenced by getDescription().
| virtual std::string CameraStreamBehavior::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.
