Custom mouse movement algorithm

[Zenz101 1]

There is a class called MouseAlgorithm to set a custom algorithm with Mouse#SetMouseAlgorithm. In said class there is a function called #handleMovement(AbstractMouseDestination destination). What do I do in this method? Call Mouse#hop(x, y) until I have reached the destination or do I have to do something else to use this correctly? I calculate the spline myself as well as the winding. Does Mouse#hop send MOUSE_MOVED events to the canvas?

I tried to decompile the classes with IntelliJ FernFlower but for every method it says it can't decompile. Is there any other method to get more insight in what the API functions do without trial-and-error?
