Member Function Documentation

const rpl_sid* Gtid_log_event::get_sid

(

)

const [inline]

Return the SID for this GTID. The SID is shared with the Log_event so it should not be modified.

rpl_sidno Gtid_log_event::get_sidno

(

bool

need_lock

)

[inline]

Return the SIDNO relative to the global sid_map for this GTID.

This requires a lookup and possibly even update of global_sid_map, hence global_sid_lock must be held. If global_sid_lock is not held, the caller must pass need_lock=true. If there is an error (e.g. out of memory) while updating global_sid_map, this function returns a negative number.

Parameters:

need_lock

If true, the read lock on global_sid_lock is acquired and released inside this function; if false, the read lock or write lock must be held prior to calling this function.

Return values:

SIDNO	if successful
negative	if adding SID to global_sid_map causes an error.

rpl_sidno Gtid_log_event::get_sidno

(

Sid_map *

sid_map

)

[inline]

Return the SIDNO relative to the given Sid_map for this GTID.

This assumes that the Sid_map is local to the thread, and thus does not use locks.

Parameters:

sid_map

The sid_map to use.

Return values:

SIDNO

if successful. if adding SID to sid_map causes an error.

enum_group_type Gtid_log_event::get_type

(

)

const [inline]

Return the group type for this Gtid_log_event: this can be either ANONYMOUS_GROUP, AUTOMATIC_GROUP, or GTID_GROUP.

Member Data Documentation

const int Gtid_log_event::POST_HEADER_LENGTH [static]

Initial value:

    ENCODED_FLAG_LENGTH + ENCODED_SID_LENGTH + ENCODED_GNO_LENGTH

Total length of post header.
