Interface: sql_reader  - X-Ref

Log iterator reader interface.

Replaces sql_select_reader adding functions
to return iterators.

get_events_select($selectwhere, array $params, $sort, $limitfrom, $limitnum)   X-Ref
Fetch records using given criteria.

param: string $selectwhere
param: array $params
param: string $sort
param: int $limitfrom
param: int $limitnum
return: \core\event\base[]

get_events_select_count($selectwhere, array $params)   X-Ref
Return number of events matching given criteria.

param: string $selectwhere
param: array $params
return: int

get_events_select_iterator($selectwhere, array $params, $sort, $limitfrom, $limitnum)   X-Ref
Fetch records using the given criteria returning an traversable list of events.

Note that the returned object is Traversable, not Iterator, as we are returning
EmptyIterator if we know there are no events, and EmptyIterator does not implement
Countable {@link https://bugs.php.net/bug.php?id=60577} so valid() should be checked
in any case instead of a count().

Also note that the traversable object contains a recordset and it is very important
that you close it after using it.

param: string $selectwhere
param: array $params
param: string $sort
param: int $limitfrom
param: int $limitnum
return: \Traversable|\core\event\base[] Returns an iterator containing \core\event\base objects.

get_log_event($data)   X-Ref
Returns an event from the log data.

param: stdClass $data Log data
return: \core\event\base
