Developing Java Code

Use the code entry tabs in the

Java

view to write and compile Java code that defines transformation behavior for specific transformation events.

You can develop code snippets on the code entry tabs in any order. You can view, but not edit, the full Java code on the

Full Code

tab.

After you develop code snippets, you can compile the code snippets or the full Java code and view the results of the compilation in the

Results

window in the

Compilation

properties in the

Java

view.

Each code entry tab contains components that you use to write, view, and compile Java code:

Code properties: Provides controls that let you view and enter Java code, including Java transformation API methods. The following table describes the controls that are available in
Code
properties:

Control
Description

Navigator

Shows input ports, output ports, and callable Java transformation API methods.

Click an item in the navigator to display a description of the item.

Double-click an item to add it to the
Java code
window. Alternatively, you can drag an item from the navigator into the
Java code
window.

The navigator is available on the following code entry tabs:

Helpers

On Input

At End

Java code
window

Enables you to view or enter Java code for the transformation. The
Java code
window displays Java code by using the basic Java syntax highlighting.

On the
Full Code
tab, you can view but not edit the full class code for the Java transformation.

The
Java code
window is available on the following code entry tabs:

New Function
command

Opens the
Define Function
dialog box that you use to define functions that invoke Java expressions.

The
Function
command is available on the
Functions
tab.

Editing toolbar

Enables you to click tool icons, such as cut, copy, and paste, to edit Java code.

The editing toolbar is available on the following code entry tabs:

command

Compiles the Java code for the transformation.

Results
window

Displays the compilation results for the Java transformation class and enables you to find the source of errors in the code.

To find an error in the code, right-click an error message in the
Results
window and select to view the error in the snippet code or in the full code.

You can also double-click an error message in the
Results
window to find its source.
