PHP Class Predis\Collection\Iterator\ListKey

This iterator tries to emulate the behaviour of cursor-based iterators based on the SCAN-family of commands introduced in Redis <= 2.8, meaning that due to its incremental nature with multiple fetches it can only offer limited guarantees on the returned elements because the collection can change several times (trimmed, deleted, overwritten) during the iteration process.

Méthodes protégées

Méthode	Description
executeCommand ( ) : array	Fetches a new set of elements from the remote collection, effectively advancing the iteration process.
extractNext ( )	Extracts next values for key() and current().
fetch ( )	Populates the local buffer of elements fetched from the server during the iteration.
requiredCommand ( Predis\ClientInterface $client, string $commandID )	Ensures that the client instance supports the specified Redis command required to fetch elements from the server to perform the iteration.
reset ( )	Resets the inner state of the iterator.
