CB Field API viewing rights

Hello

I have a question regarding CB Field API and the viewing rights parameter.

To understand clearly if I set $cbUser->getField( 'cb_ndb_models_clients' , 'Default Value', 'php', 'none', 'profile', 0, false);
does it mean that if the cbUser has no rights to use or view the field it will defaults to Default Value ? or will it throw an error ?

Thanks for the precision

does it mean that if the cbUser has no rights to use or view the field it will defaults to Default Value ? or will it throw an error ?

It will output the default only if the field is inaccessible. That function does not throw errors.
