- All Known Implementing Classes:
ResourceDiff
public interface IResourceDiff extends ITwoWayDiff
A resource diff represents the changes between two resources. The diff can be used to describe the change between an ancestor and remote, an ancestor and local or between the local and a remote for two-way comparisons.- Since:

- This interface is not intended to be implemented by clients.
Clients that need to create deltas should instead use or

getResource
IResource getResource()
Return the local resource to which this diff applies.- Returns:
- the local resource to which this diff applies
-
getBeforeState
IFileRevision getBeforeState()
Return a handle to the file state representing the "before" state of the file used to calculate this diff. Anull
is returned if the resource is not a file or if the file does not exist in the before state. If a file state is returned, clients should still check theIFileState.exists()
method to see if the file existed in the before state.- Returns:
- a handle to the file state representing the "before" state used to calculate this diff
-
getAfterState
IFileRevision getAfterState()
Return a handle to the file state representing the "after" state of the file used to calculate this diff. Anull
is returned if the resource is not a file or if the file does not exist in the after state. If a file state is returned, clients should still check theIFileState.exists()
method to see if the file existed in the after state.- Returns:
- a handle to the file state representing the "before" state used to calculate this diff
