◆ after_applier_prepare()

int Transaction_consistency_info::after_applier_prepare ( my_thread_id  thread_id,
Group_member_info::Group_member_status  member_status 
)

Call action after this transaction being prepared on this member applier.

Parameters
[in]thread_idthe applier thread id
[in]member_statusthis member status
Returns
Operation status
Return values
0OK
!=0error

◆ get_consistency_level()

enum_group_replication_consistency_level Transaction_consistency_info::get_consistency_level ( )

Get the transaction consistency.

Returns
the consistency

◆ get_gno()
