Main classes in the JFreeReport class library.
Some rules when working with the report definition objects:
- Functions cannot be added to the report once the report generation has
started.
- Do not modify the report structure after the report
generation is started, unless you know exactly what you are doing.
- It is safe to modify the report definition before the report is
started.
- Once the report processing has started, the report from the report
processor must not be reused for other purposes.
