Interface DoubleConsumer

    All Known Implementing Classes:
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    public 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).

      • accept

        void accept​(double value)
        Performs this operation on the given argument.
        value - the input argument
      • andThen

        default DoubleConsumer andThen​(DoubleConsumer after)
        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.
        after - the operation to perform after this operation
        a composed DoubleConsumer that performs in sequence this operation followed by the after operation
        NullPointerException - if after is null
