Detailed Description

Holds information about a GTID: the sidno and the gno.

This is a POD. It has to be a POD because it is part of Gtid_specification, which has to be a POD because it is used in THD::variables.

Here is the caller graph for this function:

enum_return_status Gtid::parse	(	Sid_map *	sid_map,
		const char *	text
	)

Here is the caller graph for this function:

int Gtid::to_string	(	const rpl_sid &	sid,
		char *	buf
	)		const

Convert a Gtid to a string.

Parameters

	sid	the sid to use. This overrides the sidno of this Gtid.
[out]	buf	Buffer to store the Gtid in (normally MAX_TEXT_LENGTH+1 bytes long).

Returns

Length of the string, not counting '\0'.

int Gtid::to_string	(	const Sid_map *	sid_map,
		char *	buf
	)		const

Convert this Gtid to a string.

Parameters

	sid_map	sid_map to use when converting sidno to a SID.
[out]	buf	Buffer to store the Gtid in (normally MAX_TEXT_LENGTH+1 bytes long).

Returns

Length of the string, not counting '\0'.
