Sequences don't hold a reference to the items of the collection. They're created based on the iterator of the original collection and keep a ...

kotlin-stdlib / kotlin.sequences / Sequence Sequence Common JVM JS Native 1.0 interface Sequence<out T> (source) A sequence that returns values through its iterator. The values are evaluated lazily, and the sequence is potentially infinite.

Sequences are a key abstraction to functional programming in Kotlin, a concept quite similar to Java 8 Streams. Sequences enable you to easily ...

Feb 11, 2021 · Sequences. Sequences. . Along with collections, the Kotlin standard library contains another container type – sequences ( Sequence<T> ). Sequences offer the same functions as Iterable but implement another approach to multi-step collection processing. When the processing of an Iterable includes multiple steps, they are executed eagerly ...

06.01.2010 · fun BooleanArray. asSequence (): Sequence < Boolean > fun CharArray . asSequence ( ) : Sequence < Char > (source) Creates a Sequence instance that wraps the original array returning its elements when being iterated.

Overview

Sequences. Now, let's understand the above through sequences. We can convert a collection to sequence using the asSequence() function, so the ...

Mar 07, 2019 · A sequence is an iterable type that can be operated upon without creating unnecessary intermediate collections, by running all applicable operations on each element before moving onto the next. In this definition, the word iterable does not refer to the Kotlin type Iterable .

Creating Sequences

A sequence is a container Sequence<T> with type T. It's also an interface, including intermediate operations like map() and filter(), as well as ...

The biggest selling point for Java streams over Kotlin sequences is that streams can be run in parallel. Sequences do not run in parallel - ...

You can use generateSequence factory method: generateSequence(0) { it + 2 }.forEach { println(it) }. or for the limited case:

The latter sequences throw an exception on an attempt to iterate them the second time. Sequence operations, like Sequence.map, Sequence.filter etc, generally preserve that property of a sequence, and again it's documented for an operation if it doesn't. Parameters. T - the type of elements in the sequence.
