#apply_filters(mio, options, block) ⇒ Object

def apply_filters(mio, options, block)
  if block
    block.call(mio)
  else
    default_mio_filter_block(options).call(mio)
  end
  mio
end

#cleanup_path_get_relative_pathname(path) ⇒ Object

clean up ../.. check if path starts with root path and if so get relative, otherwise return path, root_path is only used in FileMIO, so all others just simply clean the path. FileMIO will override this with its own implementation.
