Michael Dürig commented on JCR-1983:
------------------------------------
The patch adds an interface o.a.j.spi.commons.batch.ChangeLog. A ChangeLog is a
specialized Batch which keeps a list of Operations. The apply method applies
these operations to another batch.
There are two implementations of the ChangLog interface in the patch:
ChangeLogImpl and ConsolidatingChangeLog.
ChangeLogImpl implements the default behavior for a ChangeLog.
ConsolidatingChangeLog is a specialization of ChangeLogImpl and does some
simple consolidation (i.e. addNode followed by deleteNode operations cancel
each other).
> Provide change log consolidator
