This number defines how many flow items the rack will be allowed to hold at a given time.
This field returns a value of how long a flow item must stay in the rack before it is released to continue downstream. You can also return a value of -1 from this function so the rack will not release the item at all, and then implement your own releasing strategy using the releaseitem() command.
