Member Function Documentation

◆ close()

bool PortAudioRecorderDeviceDriver::close ( )
overridevirtual

Close the DeviceDriver.

Returns
true/false on success/failure.

Reimplemented from yarp::dev::DeviceDriver.

Definition at line 243 of file PortAudioRecorderDeviceDriver.cpp.

◆ getRecordingAudioBufferCurrentSize()

bool PortAudioRecorderDeviceDriver::getRecordingAudioBufferCurrentSize ( yarp::dev::AudioBufferSize size)
overridevirtual

Implements yarp::dev::IAudioGrabberSound.

Definition at line 411 of file PortAudioRecorderDeviceDriver.cpp.

◆ getRecordingAudioBufferMaxSize()

bool PortAudioRecorderDeviceDriver::getRecordingAudioBufferMaxSize ( yarp::dev::AudioBufferSize size)
overridevirtual

Implements yarp::dev::IAudioGrabberSound.

Definition at line 418 of file PortAudioRecorderDeviceDriver.cpp.

◆ getSound()

bool PortAudioRecorderDeviceDriver::getSound ( yarp::sig::Sound sound,
size_t  min_number_of_samples,
size_t  max_number_of_samples,
double  max_samples_timeout_s 
)
overridevirtual

Get a sound from a device.

Examples: getSound(s, 0, 100, 0.1); returns a sound whose size can vary between 0 and 100, with a maximum blocking time of 0.1 getSound(s, 100, 100, 0.0); returns a sound with exact size of 100. It may block forever (more specifically, until sound size is at least 100). getSound(s, 100, 100000, 0.0); returns a sound with a minimum size of 0, while trying to transfer all the internal buffer. It may block forever (more specifically, until sound size is at least 100).

Parameters
soundthe sound to be filled
min_number_of_samples.The function will block until the driver is able to collect at least min_number_of_samples. If set to zero, the function may return empty sounds.
max_number_of_samples.The function will block until the driver is either able to collect max_number_of_samples or the timeout expires.
max_samples_timeout_s.The timeout (in seconds) to retrieve max_number_of_samples.
Returns
true upon success, false for an invalid set of parameters, such as max_number_of_samples<min_number_of_samples, etc.

Implements yarp::dev::IAudioGrabberSound.

Definition at line 294 of file PortAudioRecorderDeviceDriver.cpp.

◆ handleError()

void PortAudioRecorderDeviceDriver::handleError ( )
protected

Definition at line 230 of file PortAudioRecorderDeviceDriver.cpp.

◆ open() [1/2]

bool PortAudioRecorderDeviceDriver::open ( PortAudioRecorderDeviceDriverSettings config)

Configures the device.

rate: Sample rate to use, in Hertz. Specify 0 to use a default.

samples: Number of samples per call to getSound. Specify 0 to use a default.

channels: Number of channels of input. Specify 0 to use a default.

Returns
true on success

Definition at line 162 of file PortAudioRecorderDeviceDriver.cpp.

◆ open() [2/2]

bool PortAudioRecorderDeviceDriver::open ( yarp::os::Searchable config)
overridevirtual

Open the DeviceDriver.

Parameters
configis 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 152 of file PortAudioRecorderDeviceDriver.cpp.

◆ operator=() [1/2]

PortAudioRecorderDeviceDriver& PortAudioRecorderDeviceDriver::operator= ( const PortAudioRecorderDeviceDriver )

PortAudioRecorderDeviceDriver& PortAudioRecorderDeviceDriver::operator= ( PortAudioRecorderDeviceDriver &&  )

◆ resetRecordingAudioBuffer()

bool PortAudioRecorderDeviceDriver::resetRecordingAudioBuffer ( )
overridevirtual

Implements yarp::dev::IAudioGrabberSound.

Definition at line 425 of file PortAudioRecorderDeviceDriver.cpp.

◆ run()

void PortAudioRecorderDeviceDriver::run ( )
overridevirtual

Main body of the new thread.

Override this method to do what you want. After Thread::start is called, this method will start running in a separate thread. It is important that this method either keeps checking Thread::isStopping to see if it should stop, or you override the Thread::onStop method to interact with it in some way to shut the new thread down. There is no really reliable, portable way to stop a thread cleanly unless that thread cooperates.

Implements yarp::os::Thread.

Definition at line 382 of file PortAudioRecorderDeviceDriver.cpp.

◆ startRecording()

bool PortAudioRecorderDeviceDriver::startRecording ( )
overridevirtual

Start the recording.

Returns
true/false upon success/failure

Implements yarp::dev::IAudioGrabberSound.

Definition at line 266 of file PortAudioRecorderDeviceDriver.cpp.

◆ stopRecording()

bool PortAudioRecorderDeviceDriver::stopRecording ( )
overridevirtual

Stop the recording.

Returns
true/false upon success/failure

Implements yarp::dev::IAudioGrabberSound.

Definition at line 280 of file PortAudioRecorderDeviceDriver.cpp.

◆ threadInit()

bool PortAudioRecorderDeviceDriver::threadInit ( )
overridevirtual

Initialization method.

The thread executes this function when it starts and before "run". This is a good place to perform initialization tasks that need to be done by the thread itself (device drivers initialization, memory allocation etc). If the function returns false the thread quits and never calls "run". The return value of threadInit() is notified to the class and passed as a parameter to afterStart(). Note that afterStart() is called by the same thread that is executing the "start" method.

Reimplemented from yarp::os::Thread.

Definition at line 376 of file PortAudioRecorderDeviceDriver.cpp.

◆ threadRelease()

void PortAudioRecorderDeviceDriver::threadRelease ( )
overridevirtual

Release method.

The thread executes this function once when it exits, after the last "run". This is a good place to release resources that were initialized in threadInit() (release memory, and device driver resources).

Reimplemented from yarp::os::Thread.
