IndexDiff
public IndexDiff(Repository repository, java.lang.String revstr, WorkingTreeIterator workingTreeIterator) throws java.io.IOException
Construct an IndexDiff- Parameters:
repository
-revstr
- symbolic name e.g. HEAD An EmptyTreeIterator is used ifrevstr
cannot be resolved.workingTreeIterator
- iterator for working directory- Throws:
java.io.IOException
-
IndexDiff
public IndexDiff(Repository repository, ObjectId objectId, WorkingTreeIterator workingTreeIterator) throws java.io.IOException
Construct an Indexdiff- Parameters:
repository
-objectId
- tree id. If null, an EmptyTreeIterator is used.workingTreeIterator
- iterator for working directory- Throws:
java.io.IOException
-
-
Method Detail
-
setIgnoreSubmoduleMode
public void setIgnoreSubmoduleMode(SubmoduleWalk.IgnoreSubmoduleMode mode)
- Parameters:
mode
- defines how modifications in submodules are treated- Since:
- 3.6
-
setWorkingTreeItFactory
public void setWorkingTreeItFactory(IndexDiff.WorkingTreeIteratorFactory wTreeIt)
Allows higher layers to set the factory for WorkingTreeIterators.- Parameters:
wTreeIt
-- Since:
- 3.6
-
setFilter
public void setFilter(TreeFilter filter)
Sets a filter. Can be used e.g. for restricting the tree walk to a set of files.- Parameters:
filter
-
-
diff
public boolean diff() throws java.io.IOException
Run the diff operation. Until this is called, all lists will be empty. Usediff(ProgressMonitor, int, int, String)
if a progress monitor is required.- Returns:
- if anything is different between index, tree, and workdir
- Throws:
java.io.IOException
-
diff
public boolean diff(ProgressMonitor monitor, int estWorkTreeSize, int estIndexSize, java.lang.String title) throws java.io.IOException
Run the diff operation. Until this is called, all lists will be empty.The operation may be aborted by the progress monitor. In that event it will report what was found before the cancel operation was detected. Callers should ignore the result if monitor.isCancelled() is true. If a progress monitor is not needed, callers should use
diff()
instead. Progress reporting is crude and approximate and only intended for informing the user.- Parameters:
monitor
- for reporting progress, may be nullestWorkTreeSize
- number or estimated files in the working treeestIndexSize
- number of estimated entries in the cachetitle
-- Returns:
- if anything is different between index, tree, and workdir
- Throws:
java.io.IOException
-
getAdded
public java.util.Set<java.lang.String> getAdded()
- Returns:
- list of files added to the index, not in the tree
-
getChanged
public java.util.Set<java.lang.String> getChanged()
- Returns:
- list of files changed from tree to index
-
getRemoved
public java.util.Set<java.lang.String> getRemoved()
- Returns:
- list of files removed from index, but in tree
-
getMissing
public java.util.Set<java.lang.String> getMissing()
- Returns:
- list of files in index, but not filesystem
-
getModified
public java.util.Set<java.lang.String> getModified()
- Returns:
- list of files modified on disk relative to the index
-
getUntracked
public java.util.Set<java.lang.String> getUntracked()
- Returns:
- list of files that are not ignored, and not in the index.
-
getConflicting
public java.util.Set<java.lang.String> getConflicting()
- Returns:
- list of files that are in conflict, corresponds to the keys of
getConflictingStageStates()
-
getConflictingStageStates
public java.util.Map<java.lang.String,IndexDiff.StageState> getConflictingStageStates()
- Returns:
- the map from each path of
getConflicting()
to its correspondingIndexDiff.StageState
- Since:
- 3.0
-
getIgnoredNotInIndex
public java.util.Set<java.lang.String> getIgnoredNotInIndex()
The method returns the list of ignored files and folders. Only the root folder of an ignored folder hierarchy is reported. If a/b/c is listed in the .gitignore then you should not expect a/b/c/d/e/f to be reported here. Only a/b/c will be reported. Furthermore only ignored files / folders are returned that are NOT in the index.- Returns:
- list of files / folders that are ignored
-
getAssumeUnchanged
public java.util.Set<java.lang.String> getAssumeUnchanged()
- Returns:
- list of files with the flag assume-unchanged
-
getUntrackedFolders
public java.util.Set<java.lang.String> getUntrackedFolders()
- Returns:
- list of folders containing only untracked files/folders
-
getIndexMode
public FileMode getIndexMode(java.lang.String path)
Get the file mode of the given path in the index- Parameters:
path
-- Returns:
- file mode
-
getPathsWithIndexMode
public java.util.Set<java.lang.String> getPathsWithIndexMode(FileMode mode)
Get the list of paths that IndexDiff has detected to differ and have the given file mode- Parameters:
mode
-- Returns:
- the list of paths that IndexDiff has detected to differ and have the given file mode
- Since:
- 3.6
