MongoCursor::setFlag

(No version information available, might only be in SVN)

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

说明

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.

参数

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).

返回值

Returns this cursor.

错误/异常

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