Line protocol handler

The Line protocol handler parses simple text lines.

Options

• delay: Delay of reading in milliseconds (default 0). DEPRECATED: use scheduler.delay instead if not used together with delayeach
• nanodelay: Delay of reading in nanoseconds (default 0).
• delayeach: The number of lines between a delay is used (default 0).
• readfirstline: Should the first line of the file be ignored (e.g. because of header information) (default: true)
• debug: If set to true, some additional thinks are available: (default false)
• dumpEachLine: Dumps lines to the console. if set to 1 each line will be dumped
• measureEachLine: Measures the processing time between n elements that are dumped
• lastLine/maxLines: Stop processing after n elements are read
