      .before()

      Description of the method

      Description: .before() method returns true if the date given is before the date given as a parameter.
      Available for: ISO Date, ISO Date Time
      Parameters: -
      Return type: ISO Date, ISO Date Time

       Example

      Context: HeaderType1
      OCL: self.Timestamp.before(self.Dt)
      Description: The example rule compares the date of <TimeStamp> to the date of <Dt>. If the date of  <TimeStamp> is before the date of <Dt>, true will be returned.

       

      The XML snippet below would pass this check.

      <Header>
          <Dt>2018-05-30</Dt>
          <TimeStamp>2018-05-28T12:17:50</TimeStamp>
      </Header>

      The other snippet below however would not pass this check.

      <Header>
          <Dt>2018-05-28</Dt>
          <TimeStamp>2018-05-28T12:17:50</TimeStamp>
      </Header>
