Class SshSessionFactory

java.lang.Object

org.eclipse.jgit.transport.SshSessionFactory

public abstract class SshSessionFactory
extends Object

Creates and destroys SSH connections to a remote system.

Different implementations of the session factory may be used to control communicating with the end-user as well as reading their personal SSH configuration settings, such as known hosts and private keys.

A RemoteSession must be returned to the factory that created it. Callers are encouraged to retain the SshSessionFactory for the duration of the period they are using the session.

public SshSessionFactory()

Method Detail

getInstance

public static SshSessionFactory getInstance()

Gets the currently configured JVM-wide factory.

By default the factory will read from the user's $HOME/.ssh and assume OpenSSH compatibility.

Returns:

factory the current factory for this JVM.

setInstance

public static void setInstance(SshSessionFactory newFactory)

Changes the JVM-wide factory to a different implementation.

Parameters:

newFactory - factory for future sessions to be created through; if null the default factory will be restored.

getLocalUserName

public static String getLocalUserName()

Retrieves the local user name as defined by the system property "user.name".

Returns:

the user name

getSession

public abstract RemoteSession getSession(URIish uri,
                                         CredentialsProvider credentialsProvider,
                                         FS fs,
                                         int tms)
                                  throws TransportException

Opens (or reuses) a session to a host. The returned session is connected and authenticated and is ready for further use.

Parameters:

uri - URI of the remote host to connect to

credentialsProvider - provider to support authentication, may be null if no user input for authentication is needed

fs - the file system abstraction to use for certain file operations, such as reading configuration files

tms - connection timeout for creating the session, in milliseconds

Returns:

a connected and authenticated session for communicating with the remote host given by the uri

Throws:

TransportException - if the session could not be created

getType

public abstract String getType()

The name of the type of session factory.

Returns:

the name of the type of session factory.

Since:

5.8

releaseSession

public void releaseSession(RemoteSession session)

Closes (or recycles) a session to a host.

Parameters:

session - a session previously obtained from this factory's getSession(URIish, CredentialsProvider, FS, int) method.
