Extracting an Array Element Using a Subscript Operator

Extracting an Array Element Using a Subscript Operator

Use the subscript operator in expressions to extract one or more elements of an array.
  1. In the transformation, create an output port of the same data type as the return value of the array element that you want to extract.
    To extract more than one element in an array, create an array output port. The data type of the elements in the type configuration for the array port must match the data type of the return value of the array elements.
  2. In the
    column for the output port, click the
    Expression Editor
  3. Delete the existing expression in the editor.
  4. Click the
    tab and select an array port.
  5. Enter one or more index values within the subscript operator.
    To extract array elements in a multidimensional array, enter index values within each subscript operator.
  6. Click
    to validate the expression.
  7. Click
    to exit the
    Validate Expression
    dialog box.
  8. Click
    to exit the
    Expression Editor
