function Notifications_Subscription::is_editable in Notifications 7

Same name and namespace in other branches

1. 6.4 includes/notifications_subscription.class.inc \Notifications_Subscription::is_editable()

Whether this subscription's fields are editable or not

Unless preset the 'editable' property, this is how it works:

• Once we have an instance we don't allow changing the fields, which may cause some consistency problems
• Also if the subscription type has no fields, this is not editable
• When it has fields and they've been all preset, not editable either
