public final class SquareRootFunction
extends java.lang.Object
implements java.util.function.Function<java.lang.Integer,java.lang.Integer>

Specialized utility function used by limiters to calculate thredsholds using square root of the current limit. Here we pre-compute the square root of numbers up to 1000 because the square root operation can be slow.
