Class: info_module  - X-Ref

Class handles conditional availability information for an activity.

__construct(\cm_info $cm)   X-Ref
Constructs with item details.

param: \cm_info $cm Course-module object

get_thing_name()   X-Ref
No description

set_in_database($availability)   X-Ref
No description

get_course_module()   X-Ref
Gets the course-module object. Intended for use by conditions.

return: \cm_info Course module

get_context()   X-Ref
No description

filter_user_list(array $users)   X-Ref
Tests against a user list. Users who cannot access the activity due to
availability restrictions will be removed from the list.

Note this only includes availability restrictions (those handled within
this API) and not other ways of restricting access.

This test ONLY includes conditions which are marked as being applied to
user lists. For example, group conditions are included but date
conditions are not included.

When called on a module, this test DOES also include restrictions on the
section (if any).

The function operates reasonably efficiently i.e. should not do per-user
database queries. It is however likely to be fairly slow.

param: array $users Array of userid => object
return: array Filtered version of input array

get_view_hidden_capability()   X-Ref
No description

get_user_list_sql($onlyactive = true)   X-Ref
No description

is_user_visible($cmorid, $userid = 0, $checkcourse = true)   X-Ref
Checks if an activity is visible to the given user.

Unlike other checks in the availability system, this check includes the
$cm->visible flag. It is equivalent to $cm->uservisible.

If you have already checked (or do not care whether) the user has access
to the course, you can set $checkcourse to false to save it checking
course access.

When checking for the current user, you should generally not call
this function. Instead, use get_fast_modinfo to get a cm_info object,
then simply check the $cm->uservisible flag. This function is intended
to obtain that information for a separate course-module object that
wasn't loaded with get_fast_modinfo, or for a different user.

This function has a performance cost unless the availability system is
disabled, and you supply a $cm object with necessary fields, and you
don't check course access.

param: int|\stdClass|\cm_info $cmorid Object or id representing activity
param: int $userid User id (0 = current user)
param: bool $checkcourse If true, checks whether the user has course access
return: bool True if the activity is visible to the specified user
