the ModeShape transaction

SystemException - If the transaction service fails in an unexpected way.

updateCache

public void updateCache(WorkspaceCache workspace,
                        ChangeSet changes,
                        Transactions.Transaction transaction)

Description copied from class: Transactions

Notify the workspace of the supplied changes, if and when the current transaction is completed. If the current thread is not associated with a transaction when this method is called (e.g., the transaction was started, changes were made, the transaction was committed, and then this method was called), then the workspace is notified immediately. Otherwise, the notifications will be accumulated until the current transaction is committed.

Overrides:

updateCache in class Transactions

Parameters:

workspace - the workspace to which the changes were made; may not be null

changes - the changes; may be null if there are no changes

transaction - the transaction with which the changes were made; may not be null
