MongoCursor::setFlag

(PECL mongo >=1.2.11)

MongoCursor::setFlag — Sets arbitrary flags in case there is no method available the specific flag

说明

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

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 6 (EXHAUST) as the driver does not know how to handle them. You will get a warning if you try to use this flag. 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.

更新日志

版本	说明
1.4.0	Support for flag 3 (OPLOG_REPLAY) is added. Versions before 1.4.0 would throw a warning saying that the flag is unsupported.
