Is toroid a Faraday cage?

Apart from role as a capacitor, does the toroid of a TC work along the
principle of a Faraday cage or Faraday s Ice Pail or -similar to the dome on a
Van der Graaf generator- in that the secondary is connected to the inner
surface where there is no net charge -all charge being collected on the
exterior?

Also if the inner wall of a Faraday cage has infinite electrical "suction" ie.
it can never become charged no matter how much electricity is supplied to it,
is the only difficulty in getting charge into the cage due to the repulsion of
the electric field on the outside?
