Class ChangelogState

java.lang.Object

org.opends.server.replication.server.ChangelogState

@ThreadSafe
public class ChangelogState
extends Object

This is the changelog state stored in the changelogStateDB. For each replication domain, it contains:

• its generationId
• the list of serverIds composing it

This class is used during replication initialization to decouple the code that reads the changelogStateDB from the code that makes use of its data.

                       org.forgerock.opendj.ldap.DN baseDN)

Adds the serverId to the serverIds list of the supplied replication domain.

Parameters:

serverId - the serverId to add

baseDN - the targeted replication domain baseDN

addOfflineReplica

public void addOfflineReplica(org.forgerock.opendj.ldap.DN baseDN,
                     CSN offlineCSN)

Adds the following replica information to the offline list.

Parameters:

baseDN - the baseDN of the offline replica

offlineCSN - the CSN (serverId + timestamp) of the offline replica

removeOfflineReplica

public void removeOfflineReplica(org.forgerock.opendj.ldap.DN baseDN,
                        int serverId)

Removes the following replica information from the offline list.

Parameters:

baseDN - the baseDN of the offline replica

serverId - the serverId that is not offline anymore

getDomainToGenerationId

public Map<org.forgerock.opendj.ldap.DN,Long> getDomainToGenerationId()

Returns the Map of domainBaseDN => generationId.

Returns:

a Map of domainBaseDN => generationId

getDomainToServerIds

public Map<org.forgerock.opendj.ldap.DN,Set<Integer>> getDomainToServerIds()

Returns the Map of domainBaseDN => List<serverId>.

Returns:

a Map of domainBaseDN => List<serverId>.

getOfflineReplicas

public MultiDomainServerState getOfflineReplicas()

Returns the internal MultiDomainServerState for offline replicas.

Returns:

the MultiDomainServerState for offline replicas.

isEqualTo

public boolean isEqualTo(ChangelogState other)

Returns whether the current ChangelogState is equal to the provided ChangelogState.

Note: Only use for tests!!
This method should only be used by tests because it creates a lot of intermediate objects which is not suitable for production.

Parameters:

other - the ChangelogState to compare with

Returns:

true if the current ChangelogState is equal to the provided ChangelogState, false otherwise.

toString
