BiConsumer
@FunctionalInterface interface BiConsumer<T : Any!, U : Any!>
Represents an operation that accepts two input arguments and returns no result. This is the two-arity specialization of Consumer. Unlike most other functional interfaces, BiConsumer is expected to operate via side-effects.
This is a functional interface whose functional method is accept(java.lang.Object,java.lang.Object).
Summary
| Public methods |
| abstract Unit |
Performs this operation on the given arguments.
|
| open BiConsumer<T, U>! |
Returns a composed BiConsumer that performs, in sequence, this operation followed by the after operation.

Public methods
accept
abstract fun accept(
t: T,
u: U
): Unit
Performs this operation on the given arguments.
| Parameters |
t |
T: the first input argument |
u |
U: the second input argument |
andThen
open fun andThen(after: BiConsumer<in T, in U>!): BiConsumer<T, U>!
Returns a composed BiConsumer 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 |
BiConsumer<in T, in U>!: the operation to perform after this operation |
| Return |
BiConsumer<T, U>! |
a composed BiConsumer that performs in sequence this operation followed by the after operation |
| Exceptions |
java.lang.NullPointerException |
if after is null |
