Member Function Documentation

close()

bool DevicePipe::close ( )

overridevirtual

Close the DeviceDriver.

Returns

true/false on success/failure.

Reimplemented from yarp::dev::DeviceDriver.

Definition at line 82 of file DevicePipe.cpp.

open() [1/2]

bool DevicePipe::open ( const char *  key, yarp::dev::PolyDriver &  poly, yarp::os::Searchable &  config, const char *  comment  )

staticprotected

Definition at line 48 of file DevicePipe.cpp.

open() [2/2]

bool DevicePipe::open ( yarp::os::Searchable &  config )

overridevirtual

Open the DeviceDriver.

Parameters

config

is a list of parameters for the device. Which parameters are effective for your device can vary. See device invocation examples. If there is no example for your device, you can run the "yarpdev" program with the verbose flag set to probe what parameters the device is checking. If that fails too, you'll need to read the source code (please nag one of the yarp developers to add documentation for your device).

Returns

true/false upon success/failure

Reimplemented from yarp::dev::DeviceDriver.

Definition at line 27 of file DevicePipe.cpp.

operator=() [1/2]

DevicePipe& DevicePipe::operator= ( const DevicePipe &  )

delete

operator=() [2/2]

DevicePipe& DevicePipe::operator= ( DevicePipe &&  )

delete

startService()

bool DevicePipe::startService ( )

inlineoverridevirtual

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 from yarp::dev::IService.

Definition at line 38 of file DevicePipe.h.

stopService()

bool DevicePipe::stopService ( )

inlineoverridevirtual

Shut down the service, whatever it is.

Returns

true iff the service shut down ok.

Reimplemented from yarp::dev::IService.

Definition at line 44 of file DevicePipe.h.

updateService()

bool DevicePipe::updateService ( )

overridevirtual

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 from yarp::dev::IService.
