Constructor Detail

GtidSet

public GtidSet(String gtidSet)

Parameters:

gtidSet - gtid set comprised of closed intervals (like MySQL's executed_gtid_set).

Method Detail

getUUIDSets

public Collection<GtidSet.UUIDSet> getUUIDSets()

Get an immutable collection of the range of GTIDs for a single server.

Returns:

the GTID ranges for each server; never null

getUUIDSet

public GtidSet.UUIDSet getUUIDSet(String uuid)

Find the GtidSet.UUIDSet for the server with the specified UUID.

Parameters:

uuid - the UUID of the server

Returns:

the GtidSet.UUIDSet for the identified server, or null if there are no GTIDs from that server.

putUUIDSet

public GtidSet.UUIDSet putUUIDSet(GtidSet.UUIDSet uuidSet)

Add or replace the UUIDSet

Parameters:

uuidSet - UUIDSet to be added

Returns:

the old GtidSet.UUIDSet for the server given in uuidSet param, or null if there are no UUIDSet for the given server.

add

public boolean add(String gtid)

Parameters:

gtid - GTID ("source_id:transaction_id")

Returns:

whether or not gtid was added to the set (false if it was already there)

isContainedWithin

public boolean isContainedWithin(GtidSet other)

Determine if the GTIDs represented by this object are contained completely within the supplied set of GTIDs. Note that if two GtidSets are equal, then they both are subsets of the other.

Parameters:

other - the other set of GTIDs; may be null

Returns:

true if all of the GTIDs in this set are equal to or completely contained within the supplied set of GTIDs, or false otherwise
