示例1: onOpenStream
SkStream* FontConfigTypeface::onOpenStream(int* ttcIndex) const {
SkStream* stream = this->getLocalStream();
if (stream) {
// should have been provided by CreateFromStream()
*ttcIndex = 0;
SkAutoTUnref<SkStream> dupStream(stream->duplicate());
if (dupStream) {
return dupStream.detach();
}
// TODO: update interface use, remove the following code in this block.
size_t length = stream->getLength();
const void* memory = stream->getMemoryBase();
if (NULL != memory) {
return new SkMemoryStream(memory, length, true);
}

stream->rewind();
if (length == stream->read(allocMemory.get(), length)) {
SkAutoTUnref<SkMemoryStream> copyStream(new SkMemoryStream());

return copyStream.detach();
}
stream->rewind();

} else {

if (NULL == fci.get()) {
return NULL;
}

}示例2: onOpenStream
SkStream* FontConfigTypeface::onOpenStream(int* ttcIndex) const {
SkStream* stream = this->getLocalStream();
if (stream) {
// TODO: fix issue 1176.
// As of now open_stream will return a stream and unwind it, but the
// SkStream is not thread safe, and if two threads use the stream they
// may collide and print preview for example could still fail,
// or there could be some failures in rendering if this stream is used
// there.
stream->rewind();
stream->ref();
// should have been provided by CreateFromStream()
*ttcIndex = 0;
} else {

return NULL;
}
