◆ potential_context_restrictions()
static core_analytics\local\analyser\base::potential_context_restrictions |

Returns the possible contexts used by the analyser.
This method uses separate logic for each context level because to iterate through the list of contexts calling get_context_name for each of them would be expensive in performance terms.
This generic implementation returns all the contexts in the site for the provided context level. Overwrite it for specific restrictions in your analyser.
- Parameters
-
string | null | $query | Context name filter. |
- Return values
