Detailed Description

Tag representation so that:

• Tag_plain is trivial
• Tag_plain is standard layout Therefore, a Tag_plain object is not empty by default! Use clear() or brace-enclosed initializer list to create an empty tag. Tag_plain must be a POD because it is used in Gtid_specification

Constructor & Destructor Documentation

Tag_plain() [1/2]

mysql::gtid::Tag_plain::Tag_plain ( )

default
