collect

suspend fun <T, R> Flow<T>.collect(collector: Collector<T, R>, concurrency: Int = DEFAULT_CONCURRENCY): R

Performs collection over the elements of this. The amount of concurrency depends on the Characteristics of collector, and can be tweaked using the concurrency parameter.

this is consumed only once during collection. We recommend using a cold Flow to ensure that elements are produced only when needed.

Receiver

Flow of elements to collect

Parameters

collector

Describes how to collect the values

concurrency

Defines the concurrency limit

fun <T, R> Iterable<T>.collect(collector: NonSuspendCollector<T, R>): R

Performs collection over the elements of this in a non-concurrent fashion.

this is iterated only once during collection.

Receiver

Sequence of values to collect

Parameters

collector

Describes how to collect the values

fun <T, R> Sequence<T>.collect(collector: NonSuspendCollector<T, R>): R

Performs collection over the elements of this in a non-concurrent fashion.

this is iterated only once during collection.

Receiver

Sequence of values to collect

Parameters

collector

Describes how to collect the values

fun <T, R> Iterator<T>.collect(collector: NonSuspendCollector<T, R>): R
