script — Defines a script generator.

Synopsis

Description

This element defines a generator that executes a script to create the next value. Every time the application needs a new value, it will execute the script source code that it is inside this element. For now, only a javascript engine is available. The code execution must set the value variable to the result of the calculation.

The javascript engine used is the JDK 1.6 scripting engine, see JSR 223 specification for details.
