    • valueOf

      public DMoney valueOf(String str)
      Description copied from interface: DataType
      Parses a string and converts to the value of this type.
      The method is used to parse a literal (for example the default value defined in the model).

      Notice: the method doesn't use any locale, so the results are always the same regardless of the JVM's locale.

      Parameters:
      str - the source string
      Returns:
      the value
