Creating an Expression and Generating Java Code by Using the Define Function Dialog Box

Creating an Expression and Generating Java Code by Using the
Define Function
Dialog Box

You can create a function that invokes an expression in the
Define Function
dialog box.
Complete the following steps to create a function that invokes an expression:
  1. In the Developer, open a Java transformation or create a new Java transformation.
  2. On the
    Java Code
    tab, click
    New Function
    Define Function
    dialog box appears.
  3. Enter a function name.
  4. Optionally, enter a description for the expression.
    Enter up to 2,000 characters.
  5. Create the
    for the function.
    When you create the
    , configure the
    name, datatype, precision, and scale.
  6. On the
    tab, create an expression with the arguments that you created.
  7. To validate the expression, click
  8. Optionally, enter the expression in the
    box. Then, click
    to validate the expression.
  9. To generate Java code by using the advanced interface, select the
    Generate Advanced Code
    option. Then, click
    generates the function to invoke the expression on the
    code entry tab.
