示例1: create
AbstractAudioContext* AudioContext::create(Document& document, ExceptionState& exceptionState)
{
ASSERT(isMainThread());
if (s_hardwareContextCount >= MaxHardwareContexts) {
exceptionState.throwDOMException(
NotSupportedError,
ExceptionMessages::indexExceedsMaximumBound(
"number of hardware contexts",
s_hardwareContextCount,
MaxHardwareContexts));
return nullptr;
}
AudioContext* audioContext = new AudioContext(document);
audioContext->suspendIfNeeded();
// This starts the audio thread. The destination node's
// provideInput() method will now be called repeatedly to render
// audio. Each time provideInput() is called, a portion of the
// audio stream is rendered. Let's call this time period a "render
// quantum". NOTE: for now AudioContext does not need an explicit
// startRendering() call from JavaScript. We may want to consider
// requiring it for symmetry with OfflineAudioContext.
audioContext->startRendering();
++s_hardwareContextCount;
#if DEBUG_AUDIONODE_REFERENCES
fprintf(stderr, "%p: AudioContext::AudioContext(): %u #%u\n",
audioContext, audioContext->m_contextId, s_hardwareContextCount);
