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