    • accept

      void accept(T t) throws IOException
      Performs this operation on the given argument.
      Parameters:
      t - the input argument
      Throws:
      IOException - if an I/O error occurs.

    • andThen

      default IOConsumer<T> andThen(IOConsumer<? super T> after)
      Returns a composed IoConsumer 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 Consumer that performs in sequence this operation followed by the after operation
      Throws:
      NullPointerException - if after is null
