Changing the Type Configuration for an Array Port

Changing the Type Configuration for an Array Port

The default type configuration for an array is
string[]
, which is a one-dimensional array of strings. You can change the type configuration for the array port. Specify the data type of the array elements and the array dimension.
  1. In the transformation, select the array port for which you want to specify the type configuration.
  2. In the
    Type Configuration
    column, click the
    Open
    button.
    The
    Specify Type Configuration for Array
    dialog box appears.
    The Type Configuration dialog box for an array port shows properties that you can configure. The properties include Type, Array Dimension, Precision, and Scale. The default Type is string. The default Array Dimension is 1. Based on the default Type and Array Dimension, the default Type Configuration is string[].
  3. In the
    Type
    drop-down menu, change the data type of the elements in the array.
    For example, if the elements in the array are of type integer, select
    integer
    .
    The type configuration value appears as
    integer []
    .
  4. Optionally, in the
    Array Dimension
    drop-down menu, select a number to create a nested array.
    For example, array dimension 3 creates a nested array of 3 levels. The type configuration value appears as
    integer [] [] []
    .
  5. Optionally, configure the following properties:
    • Precision
      . Maximum number of significant digits for numeric data types, or maximum number of characters for string data types.
    • Scale
      . Maximum number of digits after the decimal point of numeric values.
  6. Click
    OK
    .
    On the
    Ports
    tab, the specified type configuration appears in the
    Type Configuration
    column of the array port.
