Edit or add flow variables using java code. The node is analogous to the Java Snippet node: In the central panel, added java code to add or modify variables. The variables available at the input are listed on the left.
It is also possible to use external java libraries (that is, libraries that are not part of java boot classpath). In order to include such external jar or zip files, add their location in the "Additional Libraries" tab using the control buttons.
You can define reusable templates with the "Create templates..." button. Templates are stored in the users workspace by default and can be accessed via the "Templates" tab.
You can hit ctrl+space to get an auto completion box with all available classes, methods and fields. When you select a class and hit enter a import statement will be generated if missing.
Note, that the snippet allows defining custom global variables and custom imports.
Exceptions in the snippet are caught by the framework and will
cause the execution to fail. If you want to stop execution, please use an
exception of class Abort
. It gives the user a nice
error message.
