- org.eclipse.emf.compare.match.resource.LocationMatchingStrategy
-
- All Implemented Interfaces:
IResourceMatchingStrategy
public class LocationMatchingStrategy extends Object implements IResourceMatchingStrategy
This implementation of a matching strategy will only use String equality on the resource URIs to try and find resource mappings. This is only applicable when comparing or merging models with version control systems like git, it makes no sense for local comparisons.

findMatch
protected Resource findMatch(Resource reference, Iterable<Resource> candidates)
Returns the first match ofreference
incandidates
. This implementation will consider two Resources to be "matches" if they have the same location.- Parameters:
reference

.- Returns:
- The first match of
reference
incandidates
.null
if none.
