    • formatToMeBi

      public static String formatToMeBi(long number)
      Formats number to Mebibytes (g/m only) without fractions and bytes as base unit. For input outside the m/g range, the input is returned. Please be aware of number overflow for larger g values. [public for testing]
      Parameters:
      number - the number to be formatted
      Returns:
      the formatted number
      See Also:

    • formatToMeBi

      public static String formatToMeBi(long number, int baseUnit)
      Formats number to Mebibytes (g/m only) without fractions. For input outside the m/g range (including t in terms of g), the input is returned. [public for testing]
      Parameters:
      number - the number to be formatted
      baseUnit - 0 = bytes, 1 = kByte, 2 = mByte, 3 = gByte, ...
      Returns:
      the formatted number

    • addPropertyIfPositiveToMeBi

      public static void addPropertyIfPositiveToMeBi(Map<String,String> properties, String key, Number value, String deflt)
      Checks, formats and adds a long megabyte value as Mebibytes property.
      Parameters:
      properties - the properties to be modified as a side effect
      key - the key in Properties to modify
      value - the number as value in megabytes to be added
      deflt - the formatted default if number is not positive, may be null for no property at all
      See Also:

    • addPropertyIfPositiveToInt

      public static void addPropertyIfPositiveToInt(Map<String,String> properties, String key, Number value, String deflt)
      Checks, formats and adds an integer deployer property.
      Parameters:
      properties - the properties to be modified as a side effect
      key - the key in Properties to modify
      value - the number as value to be added
      deflt - the formatted default if number is not positive, may be null for no property at all

    • addProperty

      public static void addProperty(Map<String,String> properties, String key, Number value, String deflt, Predicate<Number> cond, Function<Number,String> formatter)
      Checks, formats and adds a deployer property.
      Parameters:
      properties - the properties to be modified as a side effect
      key - the key in Properties to modify
      value - the value to be added
      deflt - the formatted default if number is not acceptable, may be null to add nothing as default value
      cond - checks value, if true format via formatter and add as key to properties, else (if deflt is not null, add deflt as key to properties
      formatter - the formatter for number
