"Breaking" blocks like a player does?

I'm breaking leaf blocks, and I'd like to let Minecraft figure out whether or not a sapling should drop, and which type of sapling. Is there a way I can break a block programmatically the same way a player would?
I know I can simply set the block material to air, but that won't take care of the random chance for saplings and sapling type.

Sk89q seems to just set the block to air and then simulate the item drops when using WorldEdit. He really knows what he's doing and this is how he's doing it.

 

Yeah, I don't see this as maintainable. If vanilla changes the way it decides whether or not to drop a seed or apple or whatever, then I have to go and duplicate that code. That's why I was interested in asking Minecraft to do it for me, rather than coding some custom solution that approximates my guess at how Minecraft does it.

Thanks, though! I just decided not to break the leaves, and instead let them decay on their own.

 

You can use the recently added method Block.breakNaturally().
