  • Method Details

    • accept

      void accept(T stream) throws IOException
      Invokes this callback with the given stream, reader, writer, or object.

      When dealing with a stream, reader, or writer, any resources are automatically closed when the callback returns. Thus, the callback itself does not need close the stream. However, the callback should throw an exception if the operation failed and needs to be aborted.

      Parameters:
      stream - the stream, reader, or writer
      Throws:
      IOException - if an I/O error occurred
