What does the term "throttle" mean when an object "throttles" a method

Question

More specifically, I am looking the BlackBerry 6.0 API Animator class whose constructor describes that it "Creates an Animator object that throttles update() calls at the specified frame rate." http://www.blackberry.com/developers/docs/6.0.0api/net/rim/device/api/animation/Animator.html

Does this just mean that the object triggers the update method at the specified frame rate?

Answer 1

Yes. Specifically, that means that the object limits the update() calls to that specific frame rate.

Please see Google's first definition.
