MongoCommandCursor::__construct
(PECL mongo >=1.5.0)
MongoCommandCursor::__construct — Create a new command cursor
說明
public MongoCommandCursor::__construct
( MongoClient
$connection
, string $ns
[, array $command = array()
] )In many instances, you do not have to create a MongoCommandCursor manually, but instead one of the helper functions such as MongoCollection::aggregateCursor() and MongoCollection::parallelCollectionScan(). However, if the server adds new commands that can return cursors, then manually creating MongoCommandCursor objects is required. However, it might be easier to use the MongoCommandCursor::createFromDocument() instead.
