none of the following conditions are true

Summary

Negates a group of conditions.

Syntax

none of the following conditions are true:
    - <condition>* [,]

Description

The none of the following conditions are true construct allows you to group together a series of condition statements. The statement evaluates to true only if none of the conditions listed are true.

The construct must be followed by a colon and one or more condition statements, each one on a separate line and preceded by a dash. Note that the dash that precedes each condition must be a `short dash'.

Optionally, you can add a comma after the last condition statement in the list to signify the end of the list of grouped conditions. This will separate those conditions that form part of the construct from any additional condition statements that might follow.

Example

      - the category of the customer is gold
      - the age of the customer is least 60
