option description

The schema of a configuration :

• the option types
• how they are organised in groups or even subgroups, that’s why we call them groups too.

configuration option

An option object wich has a name and a value and can be accessed from the configuration object

access rules

Global access rules are : read_write() or read_only()

default value

Default value of a configuration option. The default value can be set at instanciation time, or even at any moment. Remember that if you reset the default value, the owner reset to default

freeze

A whole configuration can be frozen (used in read only access).

A single option can be frozen too.

value owner

When an option is modified, including at the instanciation, we always know who has modified it. It’s the owner of the option.

properties

an option with properties is a option wich has property like ‘hidden’ or ‘disabled’ is an option wich has restricted acces rules.

hidden option

a hidden option has a different behaviour on regards to the access of the value in the configuration.

disabled option

a disabled option has a different behaviour on regards to the access of the value in the configuration.

mandatory option

A mandatory option is a configuration option wich value has to be set, that is the default value cannot be None.

consistency

Preserving the consistency in a whole configuration is a tricky thing, tiramisu takes care of it for you.
