Visibility

Visibility restricts service consumer's access to service elements, such as whether an application can call a visibility-restricted method. The restriction is expressed by applying visibility labels on service elements. The visibility labels are elsewhere linked to service consumers.

A service can define multiple visibility labels, but a service consumer should be granted at most one visibility label. Multiple visibility labels for a single service consumer are not supported.

If an element and all its parents have no visibility label, its visibility is unconditionally granted.

Example:

visibility: rules: - selector: google.calendar.Calendar.EnhancedSearch restriction: PREVIEW - selector: google.calendar.Calendar.Delegate restriction: INTERNAL

Here, all methods are publicly visible except for the restricted methods EnhancedSearch and Delegate.
