Class FileRepository

java.lang.Object

org.eclipse.jgit.lib.Repository

org.eclipse.jgit.internal.storage.file.FileRepository

public class FileRepository
extends Repository

Represents a Git repository. A repository holds all objects and refs used for managing source code (could by any type of file, but source code is what SCM's are typically used for). In Git terms all data is stored in GIT_DIR, typically a directory called .git. A work tree is maintained unless the repository is a bare repository. Typically the .git directory is located at the root of the work dir.

• GIT_DIR
  • objects/ - objects
  • refs/ - tags and heads
  • config - configuration
  • info/ - more configurations

This class is thread-safe.

This implementation only handles a subtly undocumented subset of git features.

Constructor Detail

FileRepository

public FileRepository(File gitDir)
               throws IOException

Construct a representation of a Git repository.

The work tree, object directory, alternate object directories and index file locations are deduced from the given git directory and the default rules by running FileRepositoryBuilder. This constructor is the same as saying:

 new FileRepositoryBuilder().setGitDir(gitDir).build()
 

Parameters:

gitDir - GIT_DIR (the location of the repository metadata).

Throws:

IOException - the repository appears to already exist but cannot be accessed.

See Also:

FileRepositoryBuilder

FileRepository

public FileRepository(String gitDir)
               throws IOException

A convenience API for FileRepository(File).

Parameters:

gitDir - GIT_DIR (the location of the repository metadata).

Throws:

IOException - the repository appears to already exist but cannot be accessed.

See Also:

FileRepositoryBuilder

FileRepository

public FileRepository(BaseRepositoryBuilder options)
               throws IOException

Create a repository using the local file system.

Parameters:

options - description of the repository's important paths.

Throws:

IOException - the user configuration file or repository configuration file cannot be accessed.

Method Detail

create

public void create(boolean bare)
            throws IOException

Create a new Git repository initializing the necessary files and directories.

Specified by:

create in class Repository

Parameters:

bare - if true, a bare repository is created.

Throws:

IOException - in case of IO problem

getObjectsDirectory

public File getObjectsDirectory()

Returns:

the directory containing the objects owned by this repository.

getObjectDatabase

public ObjectDirectory getObjectDatabase()

Specified by:

getObjectDatabase in class Repository

Returns:

the object database which stores this repository's data.

getRefDatabase

public RefDatabase getRefDatabase()

Specified by:

getRefDatabase in class Repository

Returns:

the reference database which stores the reference namespace.

getConfig

public FileBasedConfig getConfig()

Specified by:

getConfig in class Repository

Returns:

the configuration of this repository

getAdditionalHaves

public Set<ObjectId> getAdditionalHaves()

Objects known to exist but not expressed by Repository.getAllRefs().

When a repository borrows objects from another repository, it can advertise that it safely has that other repository's references, without exposing any other details about the other repository. This may help a client trying to push changes avoid pushing more than it needs to.

Overrides:

getAdditionalHaves in class Repository

Returns:

unmodifiable collection of other known objects.

openPack

public void openPack(File pack)
              throws IOException

Add a single existing pack to the list of available pack files.

Parameters:

pack - path of the pack file to open.

Throws:

IOException - index file could not be opened, read, or is not recognized as a Git pack file index.

scanForRepoChanges

public void scanForRepoChanges()
                        throws IOException

Description copied from class: Repository

Force a scan for changed refs.

Specified by:

scanForRepoChanges in class Repository

Throws:

IOException

notifyIndexChanged

public void notifyIndexChanged()

Description copied from class: Repository

Notify that the index changed

Specified by:

notifyIndexChanged in class Repository

getReflogReader

public ReflogReader getReflogReader(String refName)
                             throws IOException

Specified by:

getReflogReader in class Repository

Parameters:

refName -

Returns:

a ReflogReader for the supplied refname, or null if the named ref does not exist.

Throws:

IOException - the ref could not be accessed.
