CameraBehavior Class Reference
Will take images and write to log file. More...
#include <CameraBehavior.h>
Detailed Description
Will take images and write to log file.
Press the head button to take a picture, back button to write to memory stick. The leds will flash when finished writing.
The reason for this is to provide sample code for accessing vision data, and also simply because we should have a way to save pictures to memstick instead of relying solely on having wireless to transmit them over.
Image format is chosen by current config settings for the Config::vision_config::RawCamConfig::compression and Config::vision_config::RawCamConfig::channel. However, the double resolution layer is always saved instead of whatever the current config skip value indicates.

| void CameraBehavior::doEvent | ( | ) | [virtual] |
Handles event processing - determines which generator to save from and writes to current file.
The format used depends on the current config settings. If JPEG is the current choice, then a JPEG file will be written. Otherwise, RawCameraGenerator::saveFile() will be called.

| static std::string CameraBehavior::getClassDescription | ( | ) | [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

| virtual std::string CameraBehavior::getDescription | ( | ) | const [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.
