    Description of the method

     

    Description: ->excludes() method returns true if a given object can not be found in the collection.
    Available for: collections
    Parameters: object
    Return type: boolean

     

    Example

    Context: Message
    OCL: self.Transaction.Amount->excludes(30)
    Description: The example rule checks every transaction amount in the message and if the amount 30 is not found, true will be returned.

     

    The XML snippet below would pass this check.

    <?xml version="1.0" encoding="UTF-8"?>

    <Message xmlns="http://www.XMLdation.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

      <Transaction>

        </Debtor>
        <Creditor>
          <Name>Creditor1</Name>
        </Creditor>
      </Transaction>
      <Transaction>
        <Id>TransactionId2</Id>
        <Amount>35</Amount>
        <Debtor>
          <Name>Debtor2</Name>
        </Debtor>
        <Creditor>
          <Name>Creditor2</Name>
        </Creditor>
      </Transaction>
    </Message>

    The other snippet below however would not pass this check. (The first transaction amount is 30)

    <?xml version="1.0" encoding="UTF-8"?>

        <NumberOfTransactions>1</NumberOfTransactions>
      </Header>
      <Transaction>
        <Id>TransactionId1</Id>
        <Amount>30</Amount>
        <Debtor>
          <Name>Debtor1</Name>
        </Debtor>
        <Creditor>
          <Name>Creditor1</Name>
        </Creditor>
      </Transaction>
      <Transaction>
        <Id>TransactionId2</Id>
        <Amount>35</Amount>

        </Debtor>
        <Creditor>
          <Name>Creditor2</Name>
        </Creditor>
      </Transaction>
    </Message>
