Package io.openml.gearbox.interval

Class SkippingIntervalFunction<E extends Comparable<E>>

java.lang.Object

io.openml.gearbox.interval.SkippingIntervalFunction<E>

Type Parameters:

E - The type of the end point object of this interval. For example, integer type 2024 or 2025 as in the interval [2024, 2025).

All Implemented Interfaces:

Function<Interval<E>,Optional<Interval<E>>>

public class SkippingIntervalFunction<E extends Comparable<E>>
extends Object
implements Function<Interval<E>,Optional<Interval<E>>>

A Function that, given a list of Interval's and BiPredicate, locates (if any) an element interval not fully before a specified interval, runs the test predicate on that located interval, and returns that interval if the interval passes the test

Semantically, it's returning from a list of ordered intervals the first one that overlaps with the one passed to the apply(Interval); in addition that overlapping one will be returned only if the two satisfies a joint condition. For example, if the list is ["2014/2016", "2018/2020"] and the joint condition is "sub-interval of the in-list interval", then apply(Interval) would

• return "2018/2020" on "2018/2019"
• return Optional.empty() on "2022/2025"
