Interface ThrowingConsumer<T,E extends Throwable>

Type Parameters:
T - the type of the input to the operation
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 ThrowingConsumer<T,E extends Throwable>
Represents an operation that accepts a single input argument and returns no result. Unlike most other functional interfaces, ThrowingConsumer is expected to operate via side-effects. Unlike Consumer, this implementation can throw a checked exception.

  • Method Summary

    Modifier and Type
    Method
    Description
    void
    accept(T t)
    Performs this operation on the given argument.
    default ThrowingConsumer<T,? extends Throwable>
    andThen(Consumer<? super T> after)
    Returns a composed ThrowingConsumer that performs, in sequence, this operation followed by the after operation.
    default ThrowingConsumer<T,? extends Throwable>
    andThen(ThrowingConsumer<? super T,? extends Throwable> after)
    Returns a composed ThrowingConsumer that performs, in sequence, this operation followed by the after operation.

  • Method Details

    • accept

      void accept(T t) throws E
      Performs this operation on the given argument.
      Parameters:
      t - the input argument
      Throws:
      E

    • andThen

      default ThrowingConsumer<T,? extends Throwable> andThen(ThrowingConsumer<? super T,? extends Throwable> after)
      Returns a composed ThrowingConsumer 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 - the operation to perform after this operation
      Returns:
      a composed ThrowingConsumer that performs in sequence this operation followed by the after operation
      Throws:
      NullPointerException - if after is null

    • andThen

      default ThrowingConsumer<T,? extends Throwable> andThen(Consumer<? super T> after)
      Returns a composed ThrowingConsumer 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 - the operation to perform after this operation
      Returns:
      a composed ThrowingConsumer that performs in sequence this operation followed by the after operation
      Throws:
      NullPointerException - if after is null
