(PECL mongo >=1.2.11)

MongoCursor::setFlagSets arbitrary flags in case there is no method available the specific flag

Beschreibung

public MongoCursor MongoCursor::setFlag ( bool $flag [, bool $set = true ] )

The MongoCursor class has several methods for setting flags on the query object. This method is available in case the MongoDB wire protocol has acquired a new flag, and the driver has not been updated with a method for this new flag. In all other cases, the method should be used. See the "See also" section for available methods.

Parameter-Liste

flag

Which flag to set. You can not set flag 3 (OPLOG REPLAY) or flag 6 (EXHAUST) as the driver does not know how to handle them. You will get a warning if you try to use those. For available flags, please refer to the wire protocol » documentation.

set

Whether the flag should be set (TRUE) or unset (FALSE).

Rückgabewerte

Returns this cursor.

Fehler/Exceptions

Shows a warning when an unsupport flag is attempted to be set.
