Interface DoubleConsumer

All Superinterfaces:
Consumer<Double>, DoubleConsumer
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface DoubleConsumer extends Consumer<Double>, DoubleConsumer
A type-specific Consumer; provides methods to consume a primitive type both as object and as primitive.

Except for the boolean case, this interface extends both a parameterized Consumer and a type-specific JDK consumer (e.g., IntConsumer). For types missing a type-specific JDK consumer (e.g., short or float), we extend the consumer associated with the smallest primitive type that can represent the current type (e.g., int or double, respectively).

Since:
8.0.0

    • andThen

      default DoubleConsumer andThen(DoubleConsumer after)
      Returns a composed type-specific consumer that performs, in sequence, this operation followed by the after operation.
      Specified by:
      andThen in interface DoubleConsumer
      Parameters:
      after - the operation to perform after this operation.
      Returns:
      a composed Consumer that performs in sequence this operation followed by the after operation.

      API Notes:
      Implementing classes should generally override this method and keep the default implementation of the other overloads, which will delegate to this method (after proper conversions).

    • andThen

      default DoubleConsumer andThen(DoubleConsumer after)
      Returns a composed type-specific consumer that performs, in sequence, this operation followed by the after operation.

      WARNING: Overriding this method is almost always a mistake, as this overload only exists to disambiguate. Instead, override the andThen() overload that uses the JDK's primitive consumer type (e.g. IntConsumer).

      If Java supported final default methods, this would be one, but sadly it does not.

      If you checked and are overriding the version with java.util.function.XConsumer, and you still see this warning, then your IDE is incorrectly conflating this method with the proper method to override, and you can safely ignore this message.

      Parameters:
      after - the operation to perform after this operation.
      Returns:
      a composed Consumer that performs in sequence this operation followed by the after operation.
