mrpt::hwdrivers::CGenericSensor Class Referenceabstract

Detailed Description

A generic interface for a wide-variety of sensors designed to be used in the application RawLogGrabber.

Derived classes should be designed with the following execution flow in mind:

Notice that there are helper methods for managing the internal list of objects (see CGenericSensor::appendObservation).

Class Factory: This is also a factory of derived classes, through the static method CGenericSensor::createSensor

For more details on RawLogGrabber refer to the wiki page: https://www.mrpt.org/Application:RawLogGrabber

◆ appendObservations()

void CGenericSensor::appendObservations ( const std::vector< mrpt::serialization::CSerializable::Ptr > &  obj)
protected

This method must be called by derived classes to enqueue a new observation in the list to be returned by getObservations.

Passed objects must be created in dynamic memory and a smart pointer passed. Example of creation:

mrpt::obs::CObservationGPS::Ptr o = CObservationGPS::Ptr( new
CObservationGPS() );
o-> .... // Set data

If several observations are passed at once in the vector, they'll be considered as a block regarding the grabbing decimation factor.
