onRemoteCommit

void onRemoteCommit(List<List<? extends IDimension<? extends IHierarchy>>> contributionDeltas,
 List<List<? extends IDimension<? extends IHierarchy>>> removalDeltas,
 IEpoch epoch,
 long viewId,
 String remoteAddress,
 String remotePivotId,
 Properties properties)
             throws MergeException

Merges the delta hierarchies from a remote instance's commit into the underlying IDistributedActivePivot's cube's main hierarchies and notify the listeners.

Parameters:

contributionDeltas - contributionsDelta The hierarchies containing the new members. They may come from several ITransactionCommittedMessage in which case the size of the list is higher than 1. The list is aligned with removalDeltas

removalDeltas - The hierarchies containing the removed members They may come from several ITransactionCommittedMessage in which case the size of the list is higher than 1. The list is aligned with contributionDeltas

epoch - The epoch of the remote member corresponding to the commit

viewId - The ID of the view associated with this commit

remoteAddress - The address of the remote instance that have seen the deltas

remotePivotId - The ID of the remote pivot instance that have seen the deltas

properties - The properties

Throws:

MergeException - if an exception is encountered during the transaction

onInitialRemoteCommit

void onInitialRemoteCommit(List<? extends IDimension<? extends IHierarchy>> contributionsDelta,
 IEpoch epoch,
 long viewId,
 String remoteAddress,
 String applicationId,
 String remotePivotId,
 Properties properties)
                    throws MergeException

Merges the delta dimensions from a remote instance's initial commit into the underlying IDistributedActivePivot's cube's main dimensions and notify the listeners.

Parameters:

contributionsDelta - The remote contributions

epoch - The epoch associated with these delta dimensions on the remote pivot.

viewId - The ID of the view associated with this commit

remoteAddress - The address of the remote instance responsible for this commit

applicationId - The application to which the remote instance belongs

remotePivotId - The ID of the remote pivot instance responsible for this commit

properties - The properties

Throws:

MergeException - if an exception is encountered during the transaction

removeMembersFromCube

void removeMembersFromCube(Set<String> membersToRemove,
 long viewId,
 boolean discard)
                    throws MergeException

Removes all the contributions from the cluster members membersToRemove and notify the listeners.

Parameters:

membersToRemove - The addresses of the cluster members to remove

viewId - The ID of the view associated with this removal

discard - True to remove all contributions from the given remote instances.

Throws:

MergeException - if an exception is encountered during the transaction
