Extracting a Struct Element Using the Dot Operator

Extracting a Struct Element Using the Dot Operator

Use the dot operator in expressions to extract elements of a struct.
  1. In the transformation, create an output port of the same data type as the return value of the struct element that you want to extract.
  2. In the
    Expression
    column for the output port, click the
    Open
    button.
    The Expression Editor opens.
  3. Delete the existing expression in the editor.
  4. Click the
    Ports
    tab and select the struct port.
  5. Enter a dot after the port name.
    The Developer tool displays a list of elements in the struct.
    The Expression Editor shows a list of elements in the struct.
  6. Select the element that you want to extract.
  7. Click
    Validate
    to validate the expression.
  8. Click
    OK
    to exit the Validate Expression dialog box.
  9. Click
