Interface IAdjustable
Use this interface to enable shortcut calculations to adjust a summary when an underlying value changes. The idea is to avoid re-computing the summary from scratch. For example, if your summary computes the total of a set of values, you can quickly adjust this computed total when a value changes by subtracting the old value and adding the new value without having to re-compute the total from scratch. Not all types of calculations lend themselves to this shortcut behavior.
