Hi, all.
I'm watching the initiating process of SurfaceFlinger(frameworks/
base/
libs/surfaceflinger/SurfaceFlinger.cpp).
void SurfaceFlinger::instantiate() {
defaultServiceManager()->addService(
String16("SurfaceFlinger"), new SurfaceFlinger());
}
I know the Threads::run method is invoked at onFirstRef function.
And SurfaceFlinger::onFirstRef() function is called by
RefBase::incStrong.
But I don't know how exactly RefBase::incStrong method is invoked.
SurfaceFlinger class is derived from the RefBase calss.
(SurfaceFlinger -> BnSurfaceComposer -> ISurfaceComposer ->
IInterface
-> RefBase)
Is there any constructor using RefBase::incStrong method?
Is it related with strong pointer template(<sp>)?
template<typename T> template<typename U>
sp<T>::sp(U* other) : m_ptr(other)
{
if (other) other->incStrong(this);
