Member Function Documentation

can_run()

core\task\scheduled_task::can_run ( )

inherited

Informs whether this task can be run.

Return values

bool	true when this task can be run. false otherwise.

Reimplemented in cachestore_redis\task\ttl.

do_context_membership_request()

enrol_lti\task\sync_members::do_context_membership_request ( Context $context, ResourceLink $resourcelink = null, $membershipsurltemplate = '' )

protected

Performs membership service request using an LTI Context object.

If the context has a 'custom_context_memberships_url' setting, we use this to perform the membership service request. Otherwise, if a context is associated with resource link, we try first to get the members using the ResourceLink\doMembershipsService() method. If we're still unable to fetch members from the resource link, we try to build a memberships URL from the memberships URL endpoint template that is defined in the ToolConsumer profile and substitute the parameters accordingly.

Parameters

Context	$context	The context object.
ResourceLink	$resourcelink	The resource link object.
string	$membershipsurltemplate	The memberships endpoint URL template.

Return values

bool|User[]

Array of User objects upon successful membership service request. False, otherwise.

do_resourcelink_membership_request()

enrol_lti\task\sync_members::do_resourcelink_membership_request ( ResourceLink $resourcelink )
