C++ (Cpp) Queue Examples

Example #1

File: audiostream.cpp Project: Termimad/scummvm

int QueuingAudioStreamImpl::readBuffer(int16 *buffer, const int numSamples) {
	Common::StackLock lock(_mutex);
	int samplesDecoded = 0;

	while (samplesDecoded < numSamples && !_queue.empty()) {
		AudioStream *stream = _queue.front()._stream;
		samplesDecoded += stream->readBuffer(buffer + samplesDecoded, numSamples - samplesDecoded);

		if (stream->endOfData()) {
			StreamHolder tmp = _queue.pop();
			if (tmp._disposeAfterUse == DisposeAfterUse::YES)
				delete stream;
		}
	}

	return samplesDecoded;
}

Example #2

File: audiostream.cpp Project: Termimad/scummvm

void QueuingAudioStreamImpl::queueAudioStream(AudioStream *stream, DisposeAfterUse::Flag disposeAfterUse) {
	assert(!_finished);
	if ((stream->getRate() != getRate()) || (stream->isStereo() != isStereo()))
		error("QueuingAudioStreamImpl::queueAudioStream: stream has mismatched parameters");

	Common::StackLock lock(_mutex);
	_queue.push(StreamHolder(stream, disposeAfterUse));
}
