Method Detail

getNewHead

public ObjectId getNewHead()

Returns:

the object the head points at after the merge

getMergeStatus

public MergeResult.MergeStatus getMergeStatus()

Returns:

the status the merge resulted in

getMergedCommits

public ObjectId[] getMergedCommits()

Returns:

all the commits which have been merged together

getBase

public ObjectId getBase()

Returns:

base the common base which was used to produce a content-merge. May be null if the merge-result was produced without computing a common base

toString

public String toString()

Overrides:

setConflicts

public void setConflicts(Map<String,int[][]> conflicts)

Parameters:

conflicts - the conflicts to set

addConflict

public void addConflict(String path,
                        int[][] conflictingRanges)

Parameters:

path -

conflictingRanges - the conflicts to set

addConflict

public void addConflict(String path,
                        MergeResult<?> lowLevelResult)

Parameters:

path -

lowLevelResult -

getConflicts

public Map<String,int[][]> getConflicts()

Returns information about the conflicts which occurred during a MergeCommand. The returned value maps the path of a conflicting file to a two-dimensional int-array of line-numbers telling where in the file conflict markers for which merged commit can be found.

If the returned value contains a mapping "path"->[x][y]=z then this means

• the file with path "path" contains conflicts
• if y < "number of merged commits": for conflict number x in this file the chunk which was copied from commit number y starts on line number z. All numberings and line numbers start with 0.
• if y == "number of merged commits": the first non-conflicting line after conflict number x starts at line number z

Example code how to parse this data:

 MergeResult m=...;
 Map allConflicts = m.getConflicts();
 for (String path : allConflicts.keySet()) {
        int[][] c = allConflicts.get(path);
        System.out.println("Conflicts in file " + path);
        for (int i = 0; i < c.length; ++i) {
                System.out.println("  Conflict #" + i);
                for (int j = 0; j < (c[i].length) - 1; ++j) {
                        if (c[i][j] >= 0)
                                System.out.println("    Chunk for "
                                                + m.getMergedCommits()[j] + " starts on line #"
                                                + c[i][j]);
                }
        }
 }

Returns:

the conflicts or null if no conflict occurred

public Map<String,ResolveMerger.MergeFailureReason> getFailingPaths()

Returns a list of paths causing this merge to fail as returned by ResolveMerger.getFailingPaths()

Returns:

the list of paths causing this merge to fail or null if no failure occurred
