Package org.eclipse.emf.cdo.compare
Class CDOCompareUtil
java.lang.Object
org.eclipse.emf.cdo.compare.CDOCompareUtil
Provides static factory methods that return CDO-scoped
comparisons.
Two different scopes are supported:
CDOComparisonScope.AllContentstakes an arbitraryobject(includingresource nodes) and returnsmatchesfor all elements of itscontent tree. This scope has the advantage that the comparison can be rooted at specific objects that are different from (below of) the root resource. The disadvantage is that all the transitive children of this specific object are matched, whether they differ or not. Major parts of huge repositories can be loaded to the client side easily, if no attention is paid. The following method returns comparisons that are based on this scope algorithm:CDOComparisonScope.Minimaltakes aview/transactionand returnsmatchesonly for the changed elements of the entire content tree of itsroot resource. The advantage of this scope is that CDO-specific mechanisms are used to efficiently (remotely) determine the set of changed objects. Only those and their container objects are considered as matches, making this scope scale seamlessly with the overall size of a repository. The following method returns comparisons that are based on this scope algorithm:
origin side of a comparison is automatically determined by
inspecting the branch tree and used if its different from the left or right side.
The matcher used by the comparisons is based on an ID function that considers the CDOIDs of the objects.
Resources and folders are treated as normal EObjects.
