ModifiedFilesCacheImpl (Gerrit Review Plugin API Documentation)

java.lang.Object
- com.google.gerrit.server.patch.diff.ModifiedFilesCacheImpl

All Implemented Interfaces:

ModifiedFilesCache
```
public class ModifiedFilesCacheImpl
extends Object
implements ModifiedFilesCache
```
A cache for the list of Git modified files between 2 commits (patchsets) with extra Gerrit logic.
The loader of this cache wraps a GitModifiedFilesCache to retrieve the git modified files.
If the ModifiedFilesCacheKey.aCommit() is equal to Constants.EMPTY_TREE_ID, the diff will be evaluated against the empty tree, and the result will be exactly the same as the caller can get from GitModifiedFilesCache.get(GitModifiedFilesCacheKey)
