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

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.开发者_Go百科0api/net/rim/device/api/animation/Animator.html

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

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

Please see Google's first definition.
