    • stripComments

      public static String stripComments​(String inputLine)
      Strip the comments from a String. Lines that begin with '#' and ';' are considered comments, as well as any part of a line after a '#'.
      Parameters:
      inputLine - A String to strip comments from.
      Returns:
      A String without comments, but otherwise identical to inputLine.

    • parse

      public static Map<String,​String> parse​(File file) throws IOException
      Return a Map using the contents of the File file. See parseBufferedReader for details of the input format.
      Parameters:
      file - A File to parse.
      Returns:
      A Map containing the key, value pairs from file.
      Throws:
      IOException - if file cannot be read.

    • parse

      public static Map<String,​String> parse​(File file, Map<String,​String> map)
      Return a Map using the contents of the File file. If file cannot be read, use map instead, and write the result to where file should have been.
      Parameters:
      file - A File to attempt to parse.
      map - A Map containing values to use as defaults.
      Returns:
      A Map containing the key, value pairs from file, or if file cannot be read, map.

    • parseSubscriptions

      public static List<String> parseSubscriptions​(File file, List<String> list)
      Return a List using the contents of the File file. If file cannot be read, use list instead, and write the result to where file should have been.
      Parameters:
      file - A File to attempt to parse.
      list - The default subscriptions to be saved and returned if the file cannot be read
      Returns:
      A List consisting of one element for each line in file, or if file cannot be read, list.

    • write

      public static void write​(Map<String,​String> map, File file) throws IOException
      Write contents of Map map to the File file. Output is written with one key, value pair on each line, in the format: key=value. Write to a temp file in the same directory and then rename, to not corrupt simultaneous accesses by the router. Except on Windows where renameTo() will fail if the target exists.
      Parameters:
      map - A Map to write to file.
      file - A File to write the Map to.
      Throws:
      IOException - if file cannot be written to.
