      public static MeasureUnit.MeasurePrefix[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static MeasureUnit.MeasurePrefix valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null

    • getIdentifier

      @Deprecated public String getIdentifier()
      Deprecated.
      This API is ICU internal only.
      Returns the identifier of the prefix.
      Status:
      Internal. This API is ICU internal only.

    • getBase

      public int getBase()
      Returns the base of the prefix. For example: - if the prefix is "centi", the base will be 10. - if the prefix is "gibi", the base will be 1024.
      Status:
      Stable ICU 69.

    • getPower
