PHP Class Predis\Collection\Iterator\CursorBasedIterator

Given their incremental nature with multiple fetches, these kind of iterators offer limited guarantees about the returned elements because the collection can change several times during the iteration process.

Protected Methods

Method	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.
getScanOptions ( ) : array	Returns an array of options for the SCAN command.
requiredCommand ( Predis\ClientInterface $client, string $commandID )	Ensures that the client supports the specified Redis command required to fetch elements from the server to perform the iteration.
reset ( )	Resets the inner state of the iterator.
