I want to offset an entire range of keyframes (all) in an individual animation fcurve using python. Is there an operator or function that will do this without needing to iterate through the keyframes individually - basically like performing a move command in the graph editor (G Y, 10)?

I want to offset an entire range of keyframes (all) in an individual animation fcurve using python. Is there an operator or function that will do this without needing to iterate through the keyframes individually - basically like performing a move command in the graph editor (G Y, 10)? More specifically, I would like to apply an object's Delta Transforms into its current animation in a python script.
