java.lang.Object

it.unimi.dsi.fastutil.ints.AbstractInt2DoubleFunction

it.unimi.dsi.webgraph.algo.HyperBall.AbstractDiscountFunction

All Implemented Interfaces:

Function<java.lang.Integer,java.lang.Double>, Int2DoubleFunction, java.io.Serializable, java.util.function.Function<java.lang.Integer,java.lang.Double>, java.util.function.IntToDoubleFunction

Enclosing class:

HyperBall

public abstract static class HyperBall.AbstractDiscountFunction
extends AbstractInt2DoubleFunction

An abstract discount function is a facility to implement a discount function (so that only the Int2DoubleFunction.get(int) method must be actually implemented).

Note that by contract Int2DoubleFunction.get(int) will never be called with argument (i.e., distance) zero.
