@UnstableKMathAPI

fun <V : Comparable<V>> Buffer<V>.indicesSorted(): IntArray

Return a new array filled with buffer indices. Indices order is defined by sorting associated buffer value. This feature allows sorting buffer values without reordering its content.

indicesSortedBy

@UnstableKMathAPI

fun <V, C : Comparable<C>> Buffer<V>.indicesSortedBy(selector: (V) -> C): IntArray

indicesSortedByDescending

@UnstableKMathAPI

fun <V, C : Comparable<C>> Buffer<V>.indicesSortedByDescending(selector: (V) -> C): IntArray

indicesSortedDescending

@UnstableKMathAPI

fun <V : Comparable<V>> Buffer<V>.indicesSortedDescending(): IntArray

indicesSortedWith

@UnstableKMathAPI

fun <V> Buffer<V>.indicesSortedWith(comparator: Comparator<V>): IntArray

fun Loggable.log(block: () -> String)

fun <T : Comparable<T>> Buffer<T>.requireSorted()

Checks that the Buffer is sorted (ascending) and throws IllegalArgumentException if it is not.

fun <V : Comparable<V>> Buffer<V>.sorted(): Buffer<V>

Create a zero-copy virtual buffer that contains the same elements but in ascending order

fun <V, C : Comparable<C>> Buffer<V>.sortedBy(selector: (V) -> C): Buffer<V>

sortedByDescending

fun <V, C : Comparable<C>> Buffer<V>.sortedByDescending(selector: (V) -> C): Buffer<V>

sortedDescending

fun <V : Comparable<V>> Buffer<V>.sortedDescending(): Buffer<V>

Create a zero-copy virtual buffer that contains the same elements but in descending order

fun <T> List<T>.zipWithNextCircular(): List<Pair<T, T>>

inline fun <T, R> List<T>.zipWithNextCircular(transform: (a: T, b: T) -> R): List<R>

The same as zipWithNext, but includes link between last and first element
