DoubleConsumer

@FunctionalInterface interface DoubleConsumer

java.util.function.DoubleConsumer

Known Direct Subclasses DoubleStream.Builder, DoubleSummaryStatistics DoubleStream.Builder A mutable builder for a DoubleStream. DoubleSummaryStatistics A state object for collecting statistics such as count, min, max, sum, and average.

Represents an operation that accepts a single double-valued argument and returns no result. This is the primitive type specialization of Consumer for double. Unlike most other functional interfaces, DoubleConsumer is expected to operate via side-effects.

This is a functional interface whose functional method is accept(double).

Summary

Public methods
abstract Unit	accept(value: Double) Performs this operation on the given argument.
open DoubleConsumer!	andThen(after: DoubleConsumer!) Returns a composed DoubleConsumer that performs, in sequence, this operation followed by the after operation.

Public methods

accept

Added in API level 24

abstract fun accept(value: Double): Unit

Performs this operation on the given argument.

Parameters
value	Double: the input argument

andThen

Added in API level 24

open fun andThen(after: DoubleConsumer!): DoubleConsumer!

Returns a composed DoubleConsumer that performs, in sequence, this operation followed by the after operation. If performing either operation throws an exception, it is relayed to the caller of the composed operation. If performing this operation throws an exception, the after operation will not be performed.

Parameters
after	DoubleConsumer!: the operation to perform after this operation

Return
DoubleConsumer!	a composed DoubleConsumer that performs in sequence this operation followed by the after operation

Exceptions
java.lang.NullPointerException	if after is null
