Implemented Interfaces:: ISVNRepositoryPool

public class SVNClientManager

extends Object

implements ISVNRepositoryPool

The SVNClientManager class is used to manage SVN*Client objects as well as for providing them to a user what makes the user's work easier and his code - pretty clear and flexible.

When you don't have special needs to create, keep and manage separate SVN*Client objects by yourself, you should use SVNClientManager that takes care of all that work for you. These are some of advantages of using SVNClientManager:

If you instantiate an SVN*Client object by yourself you need to provide a run-time configuration driver - ISVNOptions - as well as an authentication and network layers driver - ISVNAuthenticationManager. When using an SVNClientManager you have multiple choices to provide and use those drivers:

     //1.default options and authentication drivers to use
     SVNClientManager clientManager = SVNClientManager.newInstance();
     
     ...
     
     //2.provided options and default authentication drivers to use
     ISVNOptions myOptions;
     ...
     SVNClientManager clientManager = SVNClientManager.newInstance(myOptions);
     
     ...
     
     //3.provided options and authentication drivers to use
     ISVNOptions myOptions;
     ISVNAuthenticationManager myAuthManager;
     ...
     SVNClientManager clientManager = SVNClientManager.newInstance(myOptions, myAuthManager);
     
     ...
     
     //4.provided options driver and user's credentials to make 
     //a default authentication driver use them 
     ISVNOptions myOptions;
     ...
     SVNClientManager 
         clientManager = SVNClientManager.newInstance(myOptions, "name", "passw");

Having instantiated an SVNClientManager in one of these ways, all the SVN*Client objects it will provide you will share those drivers, so you don't need to code much to provide the same drivers to each SVN*Client instance by yourself.

With SVNClientManager you don't need to create and keep your SVN*Client objects by youself - SVNClientManager will do all the work for you, so this will certainly bring down your efforts on coding and your code will be clearer and more flexible. All you need is to create an SVNClientManager instance.

Actually every SVN*Client object is instantiated only at the moment of the first call to an appropriate SVNClientManager's get method:

     SVNClientManager clientManager;
     ...
     //an update client will be created only at that moment when you 
     //first call this method for getting your update client, but if you
     //have already called it once before, then the method will return
     //that update client object instantiated in previous... so, it's
     //quite cheap, you see.. 
     SVNUpdateClient updateClient = clientManager.getUpdateClient();

You can provide a single event handler that will be used by all SVN*Client objects provided by SVNClientManager:

 import org.tmatesoft.svn.core.wc.ISVNEventHandler;
     
     ...
     
     ISVNEventHandler commonEventHandler;
     SVNClientManager clientManager = SVNClientManager.newInstance();
     ...
     //will be used by all SVN*Client objects
     //obtained from your client manager
     clientManager.setEventHandler(commonEventHandler);

newInstance

public static SVNClientManager newInstance()

Creates a new instance of this class using default ISVNOptions and ISVNAuthenticationManager drivers. That means this SVNClientManager will use the SVN's default run-time configuration area.
Returns:
a new SVNClientManager instance

newInstance

public static SVNClientManager newInstance(ISVNOptions options)

Creates a new instance of this class using the provided ISVNOptions and default ISVNAuthenticationManager drivers. That means this SVNClientManager will use the caller's configuration options (which correspond to options found in the default SVN's config file) and the default SVN's servers configuration and auth storage.
Parameters:
options - a config driver
Returns:
a new SVNClientManager instance

newInstance

public static SVNClientManager newInstance(ISVNOptions options,
                                           String userName,
                                           String password)

Creates a new instance of this class using the provided ISVNOptions driver and user's credentials to make a default implementation of ISVNAuthenticationManager use them. That means this SVNClientManager will use the caller's configuration options (which correspond to options found in the default SVN's config file), the default SVN's servers configuration and the caller's credentials.
Parameters:
options - a config driver
userName - a user account name
password - a user password
Returns:
a new SVNClientManager instance

newInstance

public static SVNClientManager newInstance(ISVNOptions options,
                                           ISVNAuthenticationManager authManager)

Creates a new instance of this class using the provided ISVNOptions and ISVNAuthenticationManager drivers. That means this SVNClientManager will use the caller's configuration options (which correspond to options found in the default SVN's config file) as well as authentication credentials and servers options (similar to options found in the default SVN's servers).
Parameters:
options - a config driver
authManager - an authentication driver
Returns:
a new SVNClientManager instance

Creates a new instance of this class using the provided config driver and creator of of SVNRepository objects.
Parameters:
options - a config driver
repositoryPool - a creator of SVNRepository objects
Returns:
a new SVNClientManager instance

setDebugLog

public void setDebugLog(org.tmatesoft.svn.util.ISVNDebugLog log)

Sets a logger to write debug log information to. Sets this same logger object to all SVN*Client objects instantiated by this moment.
Parameters:
log - a debug logger

setEventHandler

public void setEventHandler(ISVNEventHandler handler)

Sets an event handler to all SVN*Client objects created and kept by this SVNClientManager.
The provided event handler will be set only to only those objects that have been already created (SVN*Client objects are instantiated by an SVNClientManager at the moment of the first call to a get*Client() method). So, the handler won't be set for those ones that have never been requested. However as they are first requested (and thus created) the handler will be set to them, too, since SVNClientManager is still keeping the handler.
Parameters:
handler - an event handler

shutdownConnections

public void shutdownConnections(boolean shutdownAll)

Specified by:
shutdownConnections in interface ISVNRepositoryPool
