(mongodb >=1.3.0)

MongoDB\BSON\Timestamp::getIncrement — Returns the increment component of this Timestamp

说明

final public MongoDB\BSON\Timestamp::getIncrement ( void ) : int

The increment component of a Timestamp is its least significant 32 bits, whichs denotes the incrementing ordinal for operations within a given second. This value is read as an unsigned 32-bit integer with big-endian byte order.

Note: Because PHP's integer type is signed, some values returned by this method may appear as negative integers on 32-bit platforms. The "%u" formatter of sprintf() may be used to obtain a string representation of the unsigned decimal value.

参数

此函数没有参数。

返回值

Returns the increment component of this Timestamp.

Warning

On 32-bit systems this method may return a negative number. Although the increment and timestamp parts of the BSON timestamp type consists of two unsigned 32-bit values, PHP can not represent these on 32-bit platforms.

错误／异常

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
