Detailed Description

Represents a MySQL Global Transaction Identifier.

This class abstracts the representation of a Global Transaction Identifier.

It contains two fields, a UUID and a sequence number.

Constructor & Destructor Documentation

Gtid() [1/2]

Gtid::Gtid	(	const Uuid &	uuid,
		gno_t	gno
	)

Construct a new Gtid object.

Parameters

uuid	the uuid part of the transaction identifier.
gno	The gno part of the transaction identfier.

~Gtid()

Gtid::~Gtid ( )

virtualdefault

Destroy the Gtid object.

Gtid() [2/2]

Gtid::Gtid

(

const Gtid &

other

)

Construct a new Gtid object from another one, by deep copying its contents.

Parameters

other

the other gtid to construct this gtid from.

Member Function Documentation

get_gno()

gno_t Gtid::get_gno ( ) const

virtual

Get the sequence number of this transaction identifier.

Returns

The sequence number part of this transaction identifier.

get_uuid()

const Uuid & Gtid::get_uuid ( ) const

virtual

Get the uuid of this transaction identifier.

Returns

The uuid part of this transaction identifier.

operator!=()

bool Gtid::operator!= ( const Gtid &  other ) const

virtual

Compares two identifiers and returns whether they are different.

Parameters

other

The other transaction identifier to compare to this one.

Returns

true if the identifiers are different.

false otherwise.

operator=()

Gtid & Gtid::operator= ( const Gtid &  other )

virtual

Copy assignment.

Note that this operator will do a deep copy of the other identifier.

Parameters

other

Copies the uuid and gno of the other identifier.

Returns

a copy of the other identifier.

operator==()

bool Gtid::operator== ( const Gtid &  other ) const

virtual

Compares two identifiers and returns whether they match or not.

Parameters

other

The other transaction identifier to compare to this one.

Returns

true if the identifiers are equal.

false otherwise.

to_string()

std::string Gtid::to_string ( ) const

virtual

Gets a human readable representation of this transaction identifier.

Returns

A human readable representation of this transaction identifier.
