Type Parameters:

T - type of the target object.

Parameters:

ref - the name of the reference to update to. If ref does not start with refs/ and is not the magic names HEAD FETCH_HEAD or MERGE_HEAD, then refs/heads/ will be prefixed in front of the given name, thereby assuming it is a branch.

obj - the target object.

Returns:

the target object.

Throws:

Exception

delete

public void delete(String ref)
            throws Exception

Delete a reference.

public void reset(AnyObjectId id)
           throws Exception

Soft-reset HEAD to a detached state.

Parameters:

id - ID of detached head.

Throws:

Exception

See Also:

reset(String)

reset

public void reset(String name)
           throws Exception

Soft-reset HEAD to a different commit.

This is equivalent to git reset --soft in that it modifies HEAD but not the index or the working tree of a non-bare repository.

Parameters:

name - revision string; either an existing ref name, or something that can be parsed to an object ID.

Throws:

Exception

cherryPick

public RevCommit cherryPick(AnyObjectId id)
                     throws Exception

Cherry-pick a commit onto HEAD.

This differs from git cherry-pick in that it works in a bare repository. As a result, any merge failure results in an exception, as there is no way to recover.

Parameters:

id - commit-ish to cherry-pick.

Returns:

newly created commit, or null if no work was done due to the resulting tree being identical.

Throws:

Exception

updateServerInfo

public void updateServerInfo()
                      throws Exception

Update the dumb client server info files.

Throws:

Exception

                                  throws Exception

Ensure the body of the given object has been parsed.

Type Parameters:

T - type of object, e.g. RevTag or RevCommit.

Parameters:

object - reference to the (possibly unparsed) object to force body parsing of.

Returns:

object

Throws:

Exception

branch

public TestRepository.BranchBuilder branch(String ref)

Create a new branch builder for this repository.

Parameters:

ref - name of the branch to be constructed. If ref does not start with refs/ the prefix refs/heads/ will be added.

Returns:

builder for the named branch.

                               ObjectId obj)
                        throws Exception

Tag an object using a lightweight tag.

the tagged object

Exception

          throws MissingObjectException,
                 IncorrectObjectTypeException,
                 IOException

Run consistency checks against the object database.

This method completes silently if the checks pass. A temporary revision pool is constructed during the checking.

IncorrectObjectTypeException

IOException

packAndPrune

public void packAndPrune()
