示例1:
bool
TextureHostOGL::SetReleaseFence(const android::sp<android::Fence>& aReleaseFence)
{
if (!aReleaseFence.get() || !aReleaseFence->isValid()) {
// HWC might not provide Fence.
// In this case, HWC implicitly handles buffer's fence.
return false;
}
if (!mReleaseFence.get()) {
mReleaseFence = aReleaseFence;
} else {
android::sp<android::Fence> mergedFence = android::Fence::merge(
android::String8::format("TextureHostOGL"),
mReleaseFence, aReleaseFence);
if (!mergedFence.get()) {
// synchronization is broken, the best we can do is hope fences
// signal in order so the new fence will act like a union.
// This error handling is same as android::ConsumerBase does.
mReleaseFence = aReleaseFence;
return false;
}
mReleaseFence = mergedFence;
}
return true;
