Using the Define Function Dialog Box to Define an Expression

Using the
Define Function
Dialog Box to Define an Expression

When you define a Java expression, you configure the function, create the expression, and generate the code that invokes the expression.
You can define the function and create the expression in the
Define Function
dialog box.
To create an expression function and use the expression in a Java transformation, complete the following
  1. Configure the function that invokes the expression, including the function name, description, and parameters. You use the function parameters when you create the expression.
  2. Create the expression syntax and validate the expression.
  3. Generate the Java code that invokes the expression.
    The Developer places the code on the
    code entry tab.
After you generate the Java code, call the generated function on the appropriate code entry tab to invoke an expression or get a JExpression object, based on whether you use the simple or advanced interface.
To validate an expression when you create the expression, you must use the
Define Function
dialog box.
