Class SVNRepositoryFactory

    java.lang.Object
      org.tmatesoft.svn.core.io.SVNRepositoryFactory

public abstract class SVNRepositoryFactory
extends Object

SVNRepositoryFactory is an abstract factory that is responsible for creating an appropriate SVNRepository driver specific for the protocol to use.

Depending on what protocol a user exactly would like to use to access the repository he should first of all set up an appropriate extension of this factory. So, if the user is going to work with the repository via the custom svn-protocol (or svn+xxx) he initially calls:

     ...
     import org.tmatesoft.svn.core.internal.io.svn.SVNRepositoryFactoryImpl;
     ...
         //do it once in your application prior to using the library
         //enables working with a repository via the svn-protocol (over svn and svn+ssh)
         SVNRepositoryFactoryImpl.setup();
     ...

From this point the SVNRepositoryFactory knows how to create SVNRepository instances specific for the svn-protocol. And further on the user can create an SVNRepository instance:

         ...
         //creating a new SVNRepository instance
         String url = "svn://host/path";
         SVNRepository repository = SVNRepositoryFactory.create(SVNURL.parseURIDecoded(url));
         ...

Supported Protocols | Factory to setup
svn://, svn+xxx:// | SVNRepositoryFactoryImpl (org.tmatesoft.svn.core.internal.io.svn)
http://, https:// | DAVRepositoryFactory (org.tmatesoft.svn.core.internal.io.dav)
file:/// (FSFS only) | FSRepositoryFactory (org.tmatesoft.svn.core.internal.io.fs)

Also SVNRepositoryFactory may be used to create local FSFS-type repositories.

Constructor Detail

### SVNRepositoryFactory

    public SVNRepositoryFactory()

Method Detail

### registerRepositoryFactory

    protected static void registerRepositoryFactory(String protocol,
                                                    SVNRepositoryFactory factory)

### hasRepositoryFactory

    protected static boolean hasRepositoryFactory(String protocol)

### create

    public static SVNRepository create(SVNURL url)
                                throws SVNException

  Creates an SVNRepository driver according to the protocol that is to be used to access a repository.

  The protocol is defined as the beginning part of the URL schema. Currently SVNKit supports only svn:// (svn+ssh://) and http:// (https://) schemas.

  The created SVNRepository driver can later be "reused" for another location - that is you can switch it to another repository url not to create yet one more SVNRepository object. Use the `SVNRepository.setLocation()` method for this purpose.

  An SVNRepository driver created by this method uses a default session options driver (`ISVNSession.DEFAULT`) which does not allow to keep a single socket connection opened and commit log messages caching.

  Parameters:
    `url` - a repository location URL
  Returns:
    a protocol specific SVNRepository driver
  Throws:
    `SVNException` - if there's no implementation for the specified protocol (the user may have forgotten to register a specific factory that creates SVNRepository instances for that protocol or the SVNKit library does not support that protocol at all)
  See Also:
    `create(SVNURL, ISVNSession)`, `SVNRepository`

### create

    public static SVNRepository create(SVNURL url,
                                       ISVNSession options)
                                throws SVNException

  Creates an SVNRepository driver according to the protocol that is to be used to access a repository.

  The protocol is defined as the beginning part of the URL schema. Currently SVNKit supports only svn:// (svn+ssh://) and http:// (https://) schemas.

  The created SVNRepository driver can later be "reused" for another location - that is you can switch it to another repository url not to create yet one more SVNRepository object. Use the `SVNRepository.setLocation()` method for this purpose.

  This method allows to customize a session options driver for an SVNRepository driver. A session options driver must implement the ISVNSession interface. It manages socket connections - says whether an SVNRepository driver may use a single socket connection during the runtime, or it should open a new connection per each repository access operation. And also a session options driver may cache and provide commit log messages during the runtime.

  Parameters:
    `url` - a repository location URL
    `options` - a session options driver
  Returns:
    a protocol specific SVNRepository driver
  Throws:
    `SVNException` - if there's no implementation for the specified protocol (the user may have forgotten to register a specific factory that creates SVNRepository instances for that protocol or the SVNKit library does not support that protocol at all)

### createLocalRepository

    public static SVNURL createLocalRepository(File path,
                                               boolean enableRevisionProperties,
                                               boolean force)
                                        throws SVNException

  Creates a local blank FSFS-type repository. A call to this routine is equivalent to `createLocalRepository(path, null, enableRevisionProperties, force)`.

  Parameters:
    `path` - a repository root location
    `enableRevisionProperties` - enables or not revision property modifications
    `force` - forces operation to run
  Returns:
    a local URL (file:///) of a newly created repository
  Throws:
    `SVNException`
  Since:
    1.1
  See Also:
    `createLocalRepository(File, String, boolean, boolean)`

### createLocalRepository

    public static SVNURL createLocalRepository(File path,
                                               String uuid,
                                               boolean enableRevisionProperties,
                                               boolean force)
                                        throws SVNException

  Creates a local blank FSFS-type repository. This is just similar to the Subversion's command: `svnadmin create --fs-type=fsfs REPOS_PATH`. The resultant repository is absolutely format-compatible with Subversion.

  If `uuid` is null or not 36 chars wide, the method generates a new UUID for the repository. This UUID would have the same format as if it's generated by Subversion itself.

  If `enableRevisionProperties` is true then the method creates a `pre-revprop-change` executable file inside the `"hooks"` subdir of the repository tree. This executable file simply returns 0 thus allowing revision property modifications, which are not permitted, unless one puts such a hook into that very directory.

  If `force` is true and `path` already exists, deletes that path and creates a repository in its place.

  A call to this routine is equivalent to `createLocalRepository(path, uuid, enableRevisionProperties, force, false)`.

  Parameters:
    `path` - a repository root location
    `uuid` - a repository's uuid
    `enableRevisionProperties` - enables or not revision property modifications
    `force` - forces operation to run
  Returns:
    a local URL (file:///) of a newly created repository
  Throws:
    `SVNException`
  Since:
    1.1
  See Also:
    `createLocalRepository(File, String, boolean, boolean, boolean)`

### createLocalRepository

    public static SVNURL createLocalRepository(File path,
                                               String uuid,
                                               boolean enableRevisionProperties,
                                               boolean force,
                                               boolean pre14Compatible)
                                        throws SVNException

  Creates a local blank FSFS-type repository. This is just similar to the Subversion's command: `svnadmin create --fs-type=fsfs REPOS_PATH`. The resultant repository is absolutely format-compatible with Subversion.

  If `uuid` is null or not 36 chars wide, the method generates a new UUID for the repository. This UUID would have the same format as if it's generated by Subversion itself.

  If `enableRevisionProperties` is true then the method creates a `pre-revprop-change` executable file inside the `"hooks"` subdir of the repository tree. This executable file simply returns 0 thus allowing revision property modifications, which are not permitted, unless one puts such a hook into that very directory.

  If `force` is true and `path` already exists, deletes that path and creates a repository in its place.

  Set `pre14Compatible` to true if you want a new repository to be compatible with pre-1.4 servers.

  Parameters:
    `path` - a repository root location
    `uuid` - a repository's uuid
    `enableRevisionProperties` - enables or not revision property modifications
    `force` - forces operation to run
    `pre14Compatible` - true to create a repository with pre-1.4 format
  Returns:
    a local URL (file:///) of a newly created repository
  Throws:
    `SVNException`
  Since:
    1.1.1

### createRepositoryImpl

    protected abstract SVNRepository createRepositoryImpl(SVNURL url,
                                                          ISVNSession session)
