public abstract class SVNRepository

extends Object

The abstract class SVNRepository provides an interface for protocol specific drivers used for direct working with a Subversion repository. SVNRepository joins all low-level API methods needed for repository access operations.

In particular this low-level protocol driver is used by the high-level API (represented by the org.tmatesoft.svn.core.wc package) when an access to a repository is needed.

It is important to say that before using the library it must be configured according to implimentations to be used. That is if a repository is assumed to be accessed either via the WebDAV protocol (http:// or https://), or a custom svn one (svn:// or svn+ssh://) or immediately on the local machine (file:///) a user must initialize the library in a proper way:

 //import neccessary classes
 import org.tmatesoft.svn.core.internal.io.fs.FSRepositoryFactory;
 import org.tmatesoft.svn.core.internal.io.dav.DAVRepositoryFactory;
 import org.tmatesoft.svn.core.internal.io.svn.SVNRepositoryFactoryImpl;
 import org.tmatesoft.svn.core.SVNURL;
 import org.tmatesoft.svn.core.io.SVNRepository;
 import org.tmatesoft.svn.core.io.SVNRepositoryFactory;
 import import org.tmatesoft.svn.core.wc.SVNWCUtil;
 import import org.tmatesoft.svn.core.SVNException;
 ...
 
 //Set up connection protocols support:
 //http:// and https://
 DAVRepositoryFactory.setup();
 //svn://, svn+xxx:// (svn+ssh:// in particular)
 SVNRepositoryFactoryImpl.setup();
 //file:///
 FSRepositoryFactory.setup();
 

svn+xxx:// can be any tunnel scheme for tunneled working with a repository. xxx URL scheme is looked up in the section tunnels of the standard Subversion config file.

So, only after these setup steps the client can create http | svn | file protocol implementations of the SVNRepository abstract class to access the repository.

This is a general way how a user creates an SVNRepository driver object:

 String url="http://svn.collab.net/svn/trunk";
 String name="my name";
 String password="my password";
 repository = null;
 try { 
     repository = SVNRepositoryFactory.create(SVNURL.parseURIDecoded(url));
     ISVNAuthenticationManager authManager = 
                  SVNWCUtil.createDefaultAuthenticationManager(name, password);
     repository.setAuthenticationManager(authManager);
     ...
 } catch (SVNException e){
     e.printStackTrace();
     System.exit(1);
 }
 //work with the repository
 ... 

SVNRepository objects are not thread-safe, we're strongly recommend you not to use one SVNRepository object from within multiple threads.

Also methods of SVNRepository objects are not reenterable - that is, you can not call operation methods of an SVNRepository driver neither from within those handlers that are passed to some of the driver's methods, nor during committing with the help of a commit editor (until the editor's closeEdit() method is called).

To authenticate a user over network SVNRepository drivers use ISVNAuthenticationManager auth drivers.

Method Detail

getLocation

public SVNURL getLocation()

Returns the repository location to which this object is set. It may be the location that was used to create this object (see SVNRepositoryFactory.create(SVNURL)), or the recent one the object was set to.

Returns:

a repository location set for this driver

See Also:

setLocation(SVNURL, boolean)

setLocation

public void setLocation(SVNURL url,
                        boolean forceReconnect)
                 throws SVNException

Sets a new repository location for this object. The ability to reset an old repository location to a new one (to switch the working location) lets a developer to use the same SVNRepository object instead of creating a new object per each repository location. This advantage gives memory & coding efforts economy.

But you can not specify a new repository location url with a protocol different from the one used for the previous (essentially, the current) repository location, since SVNRepository objects are protocol dependent.

If a new url is located within the same repository, this object just switches to that url not closing the current session (i.e. not calling closeSession()).

If either a new url refers to the same host (including a port number), or refers to an absolutely different host, or this object has got no repository root location cached (hasn't ever accessed a repository yet), or forceReconnect is true, then the current session is closed, cached repository credentials (UUID and repository root directory location ) are reset and this object is switched to a new repository location.

Parameters:

url - a new repository location url

forceReconnect - if true then forces to close the current session, resets the cached repository credentials and switches this object to a new location (doesn't matter whether it's on the same host or not)

Throws:

SVNException - if the old url and a new one has got different protocols

getRepositoryUUID

public String getRepositoryUUID()

Deprecated. use getRepositoryUUID(boolean) instead

Returns:

the UUID of a repository

getRepositoryUUID

public String getRepositoryUUID(boolean forceConnection)
                         throws SVNException

Gets the Universal Unique IDentifier (UUID) of the repository this driver is created for.

Parameters:

forceConnection - if true then forces this driver to test a connection - try to access a repository

Returns:

the UUID of a repository

Throws:

SVNException

getRepositoryRoot

public SVNURL getRepositoryRoot()

Deprecated. use #getRepositoryRoot(boolean) instead

Returns:

the repository root directory location url

See Also:

getRepositoryRoot(boolean)

getRepositoryRoot

public SVNURL getRepositoryRoot(boolean forceConnection)
                         throws SVNException

Gets a repository's root directory location. If this driver object is switched to a different repository location during runtime (probably to an absolutely different repository, see setLocation()), the root directory location may be changed.

Parameters:

forceConnection - if true then forces this driver to test a connection - try to access a repository

Returns:

the repository root directory location url

Throws:

SVNException

See Also:

testConnection()

setAuthenticationManager

public void setAuthenticationManager(ISVNAuthenticationManager authManager)

Sets an authentication driver for this object. The auth driver may be implemented to retrieve cached credentials, to prompt a user for credentials or something else (actually, this is up to an implementor). Also there's a default implementation - see the SVNWCUtil class for more details.

Parameters:

authManager - an authentication driver to provide user credentials

See Also:

getAuthenticationManager()

getAuthenticationManager

public ISVNAuthenticationManager getAuthenticationManager()

Returns the authentication driver registered for this object.

Returns:

an authentication driver that is used by this object to authenticate a user over network

setTunnelProvider

public void setTunnelProvider(ISVNTunnelProvider tunnelProvider)

Sets a tunnel provider. Actually relevant only to svn+xxx:// scheme cases. The provider is responsible for matching xxx to the tunnel command string.

If one would like to have a standard Subversion behaviour (when tunnel commands are fetched from the config file beneath the section named tunnels), he should provide a default provider (default implementation of the ISVNOptions interface). Refer to SVNWCUtil class for more details on how to get a default options driver.

Parameters:

tunnelProvider - a tunnel provider

See Also:

getTunnelProvider()

getTunnelProvider

public ISVNTunnelProvider getTunnelProvider()

Returns a tunnel provider.

Returns:

a tunnel provider

                                        SVNURL rootURL)

Caches identification parameters (UUID, rood directory location) of the repository with which this driver is working.

Parameters:

uuid - the repository's Universal Unique IDentifier (UUID)

rootURL - the repository's root directory location

Returns the recent repository revision number for the particular moment in time - the closest one before or at the specified datestamp.

Example: if you specify a single date without specifying a time of the day (e.g. 2002-11-27) the timestamp is assumed to 00:00:00 and the method won't return any revisions for the day you have specified but for the day just before it.

Parameters:

date - a datestamp for defining the needed moment in time

Returns:

the revision of the repository for that time

Throws:

SVNException - if a failure occured while connecting to a repository or the user's authentication failed (see SVNAuthenticationException)

                              throws SVNException

Retrieves interesting file revisions for the specified file.

A file revision is represented by an SVNFileRevision object. Each file revision is handled by the file revision handler provided. Only those revisions will be retrieved in which the file was changed. The iteration will begin at the first such revision starting from the startRevision and so on - up to the endRevision. If the method succeeds, the provided handler will have been invoked at least once.

For the first interesting revision the file contents will be provided to the handler as a text delta against an empty file. For the following revisions, the delta will be against the fulltext contents of the previous revision.

The path arg can be both relative to the location of this driver and absolute to the repository root (starts with "/").

NOTES:

• you may not invoke methods of this SVNRepository object from within the provided handler
• this functionality is not available in pre-1.1 servers

Parameters:

path - a file path

startRevision - a revision to start from

endRevision - a revision to stop at

handler - a handler that processes file revisions passed

Returns:

the number of retrieved file revisions

Throws:

log

public long log(String[] targetPaths,
                long startRevision,
                long endRevision,
                boolean changedPath,
                boolean strictNode,
                ISVNLogEntryHandler handler)
         throws SVNException

Traverses revisions history. In other words, collects per revision information that includes the revision number, author, datestamp, log message and maybe a list of changed paths (optional). For each revision this information is represented by an SVNLogEntry object. Such objects are passed to the provided handler.

This method invokes handler on each log entry from startRevision to endRevision. startRevision may be greater or less than endRevision; this just controls whether the log messages are processed in descending or ascending revision number order.

If startRevision or endRevision is invalid, it defaults to the youngest.

If targetPaths has one or more elements, then only those revisions are processed in which at least one of targetPaths was changed (i.e., if a file text or properties changed; if dir properties changed or an entry was added or deleted). Each path is relative to the repository location that this object is set to.

If changedPath is true, then each SVNLogEntry passed to the handler will contain info about all paths changed in that revision it represents. To get them call SVNLogEntry.getChangedPaths() that returns a map, which keys are the changed paths and the values are SVNLogEntryPath objects. If changedPath is false, changed paths info will not be provided.

If strictNode is true, copy history will not be traversed (if any exists) when harvesting the revision logs for each path.

Target paths can be both relative to the location of this driver and absolute to the repository root (starts with "/").

NOTE: you may not invoke methods of this SVNRepository object from within the provided handler.

Parameters:

targetPaths - paths that mean only those revisions at which they were changed

startRevision - a revision to start from

endRevision - a revision to end at

changedPath - if true then revision information will also include all changed paths per revision, otherwise not

strictNode - if true then copy history (if any) is not to be traversed

handler - a caller's handler that will be dispatched log entry objects

Returns:

the number of revisions traversed

Throws:

SVNException - if a failure occured while connecting to a repository or the user's authentication failed (see SVNAuthenticationException)

If limit is > 0 then only the first limit log entries will be handled. Otherwise (i.e. if limit is 0) this number is ignored.

Target paths can be both relative to the location of this driver and absolute to the repository root (starts with "/").

NOTE: you may not invoke methods of this SVNRepository object from within the provided handler.

Parameters:

targetPaths - paths that mean only those revisions at which they were changed

startRevision - a revision to start from

endRevision - a revision to end at

changedPath - if true then revision information will also include all changed paths per revision, otherwise not

strictNode - if true then copy history (if any) is not to be traversed

limit - the maximum number of log entries to process

handler - a caller's handler that will be dispatched log entry objects

Returns:

the number of revisions traversed

Throws:

SVNException - if a failure occured while connecting to a repository or the user's authentication failed (see SVNAuthenticationException)

getLocations

public abstract int getLocations(String path,
                                 long pegRevision,
                                 long[] revisions,
                                 ISVNLocationEntryHandler handler)
                          throws SVNException

Gets entry locations in time. The location of an entry in a repository may change from revision to revision. This method allows to trace entry locations in different revisions.

For each interesting revision (taken from revisions) an entry location is represented by an SVNLocationEntry object which is passed to the provided handler. Each SVNLocationEntry object represents a repository path in a definite revision.

The path arg can be both relative to the location of this driver and absolute to the repository root (starts with "/").

NOTES:

• you may not invoke methods of this SVNRepository object from within the provided handler
• this functionality is not available in pre-1.1 servers

Parameters:

path - an item's path

pegRevision - a revision in which path is first looked up

revisions - an array of numbers of interesting revisions in which locations are looked up. If path doesn't exist in an interesting revision, that revision will be ignored.

handler - a location entry handler that will handle all found entry locations

Returns:

the number of the entry locations found

Throws:

SVNException - in the following cases:

• path not found in the specified pegRevision
• pegRevision is not valid
• a failure occured while connecting to a repository
• the user authentication failed (see SVNAuthenticationException)

Since:

SVN 1.1

                            throws SVNException

Retrieves and returns interesting file revisions for the specified file.

A file revision is represented by an SVNFileRevision object. Only those revisions will be retrieved in which the file was changed. The iteration will begin at the first such revision starting from the startRevision and so on - up to the endRevision.

The path arg can be both relative to the location of this driver and absolute to the repository root (starts with "/").

NOTE: this functionality is not available in pre-1.1 servers

Parameters:

path - a file path

revisions - if not null this collection will receive all the fetched file revisions

sRevision - a revision to start from

eRevision - a revision to stop at

Returns:

a collection that keeps file revisions - SVNFileRevision instances

Throws:

SVNException - if a failure occured while connecting to a repository or the user's authentication failed (see SVNAuthenticationException)

Since:

SVN 1.1

                         Collection dirEntries)
                  throws SVNException

Fetches the contents and properties of a directory located at the specified path in a particular revision. Information of each directory entry is represented by a single SVNDirEntry object.

The path arg can be both relative to the location of this driver and absolute to the repository root (starts with "/").

Parameters:

path - a directory path

revision - a revision number

properties - if not null then all directory properties (including non-tweakable ones) will be put into this map (where keys are property names and mappings are property values)

dirEntries - if not null then this collection receives fetched dir entries (SVNDirEntry objects)

Returns:

a collection containing fetched directory entries (SVNDirEntry objects)

Throws:

SVNException - in the following cases:

• path not found in the specified revision
• path is not a directory
• a failure occured while connecting to a repository
• the user authentication failed (see SVNAuthenticationException)

getDir

public abstract SVNDirEntry getDir(String path,
                                   long revision,
                                   boolean includeCommitMessages,
                                   Collection entries)
                            throws SVNException

Fetches the contents of a directory into the provided collection object and returns the directory entry itself.

If entries arg is not null it receives the directory entries. Information of each directory entry is represented by an SVNDirEntry object.

The path arg can be both relative to the location of this driver and absolute to the repository root (starts with "/").

Parameters:

path - a directory path

revision - a revision number

includeCommitMessages - if true then dir entries (SVNDirEntry objects) will be supplied with commit log messages, otherwise not

entries - a collection that receives fetched dir entries

Returns:

the directory entry itself which contents are fetched into entries

Throws:

SVNException - in the following cases:

• path not found in the specified revision
• path is not a directory
• a failure occured while connecting to a repository
• the user authentication failed (see SVNAuthenticationException)

log

public Collection log(String[] targetPaths,
                      Collection entries,
                      long startRevision,
                      long endRevision,
                      boolean changedPath,
                      boolean strictNode)
               throws SVNException

Traverses revisions history and returns a collection of log entries. In other words, collects per revision information that includes the revision number, author, datestamp, log message and maybe a list of changed paths (optional). For each revision this information is represented by an SVNLogEntry. object.

startRevision may be greater or less than endRevision; this just controls whether the log messages are processed in descending or ascending revision number order.

If startRevision or endRevision is invalid, it defaults to the youngest.

If targetPaths has one or more elements, then only those revisions are processed in which at least one of targetPaths was changed (i.e., if a file text or properties changed; if dir properties changed or an entry was added or deleted). Each path is relative to the repository location that this object is set to.

If changedPath is true, then each SVNLogEntry object is supplied with info about all paths changed in that revision it represents. To get them call SVNLogEntry.getChangedPaths() that returns a map, which keys are the changed paths and the mappings are SVNLogEntryPath objects. If changedPath is false, changed paths info will not be provided.

If strictNode is true, copy history will not be traversed (if any exists) when harvesting the revision logs for each path.

Target paths can be both relative to the location of this driver and absolute to the repository root (starts with "/").

Parameters:

targetPaths - paths that mean only those revisions at which they were changed

entries - if not null then this collection will receive log entries

startRevision - a revision to start from

endRevision - a revision to end at

changedPath - if true then revision information will also include all changed paths per revision, otherwise not

strictNode - if true then copy history (if any) is not to be traversed

Returns:

a collection with log entries

Throws:

SVNException - if a failure occured while connecting to a repository or the user's authentication failed (see SVNAuthenticationException)
