Member Function Documentation

startService()

virtual bool yarp::dev::IService::startService ( )

inlinevirtual

Initiate the service, whatever it is.

The service should then run by itself, without any further interaction with its creator until stopService() is called.

Returns

true if the service started and needs no help running. If false is returned, the service expects updateService() to be called repeatedly until that function too returns false. This is useful for devices that don't want to manage their own service threads.

Reimplemented in yarp::dev::OVRHeadset.

Definition at line 37 of file ServiceInterfaces.h.

stopService()

virtual bool yarp::dev::IService::stopService ( )

inlinevirtual

Shut down the service, whatever it is.

Returns

true iff the service shut down ok.

Reimplemented in yarp::dev::OVRHeadset.

Definition at line 57 of file ServiceInterfaces.h.

updateService()

virtual bool yarp::dev::IService::updateService ( )

inlinevirtual

Give the service the chance to run for a while.

This is an alternative to calling startService(). It is more appropriate in a single-threaded environment.

Returns

true iff the service is willing to run some more. A return value of false means that the service would like to stop.

Reimplemented in yarp::dev::OVRHeadset.
