Constructor Detail

GtidSet

protected GtidSet(Map<String,GtidSet.UUIDSet> uuidSetsByServerId)

GtidSet

public GtidSet(String gtids)

Parameters:

gtids - the string representation of the GTIDs.

Method Detail

retainAll

public GtidSet retainAll(Predicate<String> sourceFilter)

Obtain a copy of this GtidSet except with only the GTID ranges that have server UUIDs that match the given predicate.

Parameters:

sourceFilter - the predicate that returns whether a server UUID is to be included

Returns:

the new GtidSet, or this object if sourceFilter is null; never null

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

forServerWithId

public GtidSet.UUIDSet forServerWithId(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.

isContainedWithin

public boolean isContainedWithin(GtidSet other)

Determine if the GTIDs represented by this object are contained completely within the supplied set of GTIDs.

Parameters:

other - the other set of GTIDs; may be null

Returns:

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

with

public GtidSet with(GtidSet other)

Obtain a copy of this GtidSet except overwritten with all of the GTID ranges in the supplied GtidSet.

Parameters:

other - the other GtidSet with ranges to add/overwrite on top of those in this set;

Returns:

the new GtidSet, or this object if other is null or empty; never null

getGtidSetBeginning

public GtidSet getGtidSetBeginning()

Returns a copy with all intervals set to beginning

Returns:

contains

public boolean contains(String gtid)

subtract

public GtidSet subtract(GtidSet other)

hashCode

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)
