Camera.cpp

sp<Camera> Camera::connect(int cameraId, const String16& clientPackageName,
        int clientUid, int clientPid)
{
    return CameraBaseT::connect(cameraId, clientPackageName, clientUid, clientPid);
}

來到CameraBase.h

template <typename TCam, typename TCamTraits = CameraTraits<TCam> >
class CameraBase : public IBinder::DeathRecipient
{

。。。

。。。

protected:
    CameraBase(int cameraId);
    virtual              ~CameraBase();

   。。。

   。。。

    typedef CameraBase<TCam>         CameraBaseT;
};

Camera.h

class Camera :
    public CameraBase<Camera>,
    public ::android::hardware::BnCameraClient

注意這裏有繼承關係CameraBase<Camera> 把Camera傳入進去

最終致使typedef CameraBase<TCam>         CameraBaseT 就是 typedef CameraBase<Camera>         CameraBaseT
