Detailed Description

Binary Format

The Post-Header for this event type is empty. The Body has two components:

Body for Previous_gtids_event
Name	Format	Description
buf	unsigned char array	It contains the Gtids executed in the last binary log file.
buf_size	4 byte integer	Size of the above buffer

Constructor & Destructor Documentation

◆ Previous_gtids_event() [1/2]

mysql::binlog::event::Previous_gtids_event::Previous_gtids_event	(	const char *	buf,
		const Format_description_event *	fde
	)

Decodes the gtid_executed in the last binlog file.

The buffer layout is as follows
+--------------------------------------------+
| Gtids executed in the last binary log file |
+--------------------------------------------+

Parameters

buf	Contains the serialized event.
fde	An FDE event (see Rotate_event constructor for more info).

◆ Previous_gtids_event() [2/2]

mysql::binlog::event::Previous_gtids_event::Previous_gtids_event ( )

inline

This is the minimal constructor, and set the type_code as PREVIOUS_GTIDS_LOG_EVENT in the header object in Binary_log_event.
