  • Method Details

    • getSymbol

      char getSymbol()

      Gets the format symbol which is used to display this time unit in canonical representations of timespans.

      Canonical timespan formats follow ISO-8601. For example, the day unit is represented by the symbol D. Note that the letters P and T must not be used because these special characters are for structuring, the display. In ISO-8601 following symbols are defined:

      • Y - year
      • M - month or minute
      • W - week
      • D - day
      • H - hour
      • S - second
      • P - qualifies a timespan (period)
      • T - separates date and time part

      If this method yields as special case a digit 1-9 then Time4J expects a fractional display of preceding second unit S that is nanoseconds, microseconds and milliseconds. Time4J will use the comma as decimal separation char in the canonical display as recommended by ISO-8601 unless the system property "net.time4j.format.iso.decimal.dot" is set to true (which causes the usage of a dot).

      Returns:
      char (ASCII-NULL if undefined)
