示例1: Get
bool WaveTrack::Get(samplePtr buffer, sampleFormat format,
longSampleCount start, sampleCount len)
{
// Simple optimization: When this buffer is completely contained within one clip,
// don't clear anything (because we never won't have to). Otherwise, just clear
// everything to be on the safe side.
WaveClipList::Node* it;
bool doClear = true;
for (it=GetClipIterator(); it; it=it->GetNext())
{
WaveClip *clip = it->GetData();
