Binary_log_event (Log_event_type type_code) | |
This constructor is used to initialize the type_code of header object m_header. More... | |
Binary_log_event (const char **buf, const Format_description_event *fde) | |
This constructor will create a new object of Log_event_header and initialize the variable m_header, which in turn will be used to initialize Log_event's member common_header. More... | |
The Post-Header for this event type is empty. The Body has two components:
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 |
binary_log::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 | +--------------------------------------------+
buf | Contains the serialized event. |
fde | An FDE event (see Rotate_event constructor for more info). |
|
inline |
This is the minimal constructor, and set the type_code as PREVIOUS_GTIDS_LOG_EVENT in the header object in Binary_log_event.
