cached

To run a given script only once and cache and return the output value

This function allows you to cache calculations of an elaborate script during the first execution. Instead of a new calculation, the saved value is then returned.

But if you want to trigger a recalculation of your script, you have the following options:

• Activate the edit mode
• Execute the invalidate() function in any table of your database

This feature can help solve performance problems.
