Classes
class	DigitalFilter
	The DigitalFilter class is used to pass signals with a frequency lower than a certain cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. More...

class	KVDB
	Lightweight key-value database to store system-wide parameters. We prefer keys like "apollo:data:commit_id". More...

class	LatencyRecorder

class	MeanFilter
	The MeanFilter class is used to smoothen a series of noisy numbers, such as sensor data or the output of a function that we wish to be smoother. More...

class	Status
	A general class to denote the return status of an API call. It can either be an OK status for success, or a failure status with error message and error code enum. More...

class	VehicleConfigHelper

class	VehicleModel

class	VehicleStateProvider
	The class of vehicle state. It includes basic information and computation about the state of the vehicle. More...
