An input_filter filters the data read from it through the * io_obj_channel (usually a pipe after the data have been * retrieved from the passed in_obj_channel. * * An input_filter object never generates Buffer_underrun exceptions. * However, if the passed in_obj_channel or io_obj_channel raises such * an exception, the exception will fall through the calling chain. * * If the filter is closed, the io_obj_channel will be closed, too, * but not the source in_obj_channel (so you can still read further * data from it).
