Detailed Description

This class represents a set of transaction identifiers.

A set of transaction identifiers contains zero or more entries. When there are multiple entries, there can multiple intervals as well. Different intervals may share the same UUID part or not. This class abstracts that in-memory representation.

Member Typedef Documentation

◆ Gno_interval_list

typedef std::map<Uuid, std::set<Gno_interval>, Uuid_comparator> binary_log::gtids::Gtid_set::Gno_interval_list

Gno_interval_list is a map between uuids and an ordered set of Gno_intervals.

Constructor & Destructor Documentation

◆ Gtid_set() [1/2]

binary_log::gtids::Gtid_set::Gtid_set ( )

default

◆ ~Gtid_set()

virtualdefault

◆ Gtid_set() [2/2]

Gtid_set::Gtid_set ( const Gtid_set & other )

Construct a new Gtid_set object from the other one provided.

Note: This operator does not check whether the parameters are valid or not. The caller should perform such check before calling this member function.

Parameters

other Gtid_set to be copied

Member Function Documentation

◆ add() [1/3]

bool Gtid_set::add ( const Gtid & gtid )

virtual

Adds the given identifier to this set.

Note: This member function does not check whether the parameters are valid or not. The caller should perform such check before calling this member function.

Parameters

gtid	the identifier to add.

Returns: true if it failed while adding the identifier.; false otherwise.

◆ add() [2/3]

bool Gtid_set::add ( const Gtid_set & other )

virtual

Add a set of identifiers to this one.

Note: This member function does not check whether the parameters are valid or not. The caller should perform such check before calling this member function.

Parameters

other the set to add to this one.

Returns: true if there was a failure adding the gtids.; false otherwise.

◆ add() [3/3]

bool Gtid_set::add	(	const Uuid &	uuid,
		const Gno_interval &	interval
	)

virtual

Adds a new interval indexed by the given uuid.

Note: This member function does not check whether the parameters are valid or not. The caller should perform such check before calling this member function.

Returns: true if the there was an error adding the interval, false otherwise.

◆ contains()

bool Gtid_set::contains ( const Gtid & gtid ) const

virtual

Checks whether this set contains the given identifier.

Note: This member function does not check whether the parameters are valid or not. The caller should perform such check before calling this member function.

Parameters

gtid	the gtid to check whehther it exists in this set or not.

Returns: true if the identifier exists in this set.; false if the identifier does not exist in this set.

◆ count()

std::size_t Gtid_set::count ( ) const

virtual

Gets the number of entries in this set.

Returns: the cardinality of this set.

◆ do_add()

bool Gtid_set::do_add	(	const Uuid &	uuid,
		const Gno_interval &	interval
	)

protectedvirtual

◆ get_gtid_set()

const Gtid_set::Gno_interval_list & Gtid_set::get_gtid_set ( ) const

virtual

Gets a copy of the internal set.

Returns: an internal copy of the given set.

◆ is_empty()

bool Gtid_set::is_empty ( ) const

virtual

Returns true if this is an empty set.

Returns: true; false

◆ operator=()

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

Copy assignment.

Note: This operator does not check whether the parameters are valid or not. The caller should perform such check before calling this member function.

Parameters

other the Gtid_set to be copied over to this one.

Returns: Gtid_set& a reference to the copied Gtid_set.

◆ operator==()

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

virtual

Compares this set with another one.

Parameters

other The other set to compare this one with.

Returns: true If both sets match.; false If sets do not match.

◆ reset()

void Gtid_set::reset ( )

virtual

Resets this set, making it empty.

◆ to_string()

std::string Gtid_set::to_string ( ) const

virtual

A human readable representation of this set.

Returns: a human readable representation of this set.

inlinestatic

◆ m_gtid_set

Gno_interval_list binary_log::gtids::Gtid_set::m_gtid_set {}

protected

An ordered map of entries mapping Uuid to a list of intervals.

The order is established using the Uuid_comparator.

inlinestatic

In 'SID:GNO,SID:GNO', this is the ','.
