Step 3. Generate Java Code for the Expression

After you configure the function and function parameters and define and validate the expression, you can generate the Java code that invokes the expression.

The

Designer

Developer

places the generated Java code on the

Java Expressions

Functions

code entry tab. Use the generated Java code to call the functions that invoke the expression in the code entry tabs

in the Transformation Developer

. You can generate the simple or advanced Java code.

After you generate the Java code that invokes an expression, you cannot edit the expression and revalidate it. To modify an expression after you generate the code, you must create the expression again.
