Typical states are LOADING while the media is loading,
READY after it has successfully completed loading,
and LOAD_ERROR if it fails to complete loading.
If the LoadState is LOADING or READY
when the method is called, throws an error.
擲回值
IllegalOperationError — If this trait is unable to load
itself or if the LoadState is LOADING or
READY.
