Interface ClientSessionFactory

All Superinterfaces:

AutoCloseable

All Known Subinterfaces:

ClientSessionFactoryInternal

All Known Implementing Classes:

ClientSessionFactoryImpl

public interface ClientSessionFactory
extends AutoCloseable

A ClientSessionFactory is the entry point to create and configure HornetQ resources to produce and consume messages.
It is possible to configure a factory using the setter methods only if no session has been created. Once a session is created, the configuration is fixed and any call to a setter method will throw a IllegalStateException.

Method Detail

createXASession

ClientSession createXASession()
                              throws HornetQException

Creates a session with XA transaction semantics.

Returns:

a ClientSession with XA transaction semantics

Throws:

HornetQException - if an exception occurs while creating the session

createTransactedSession

ClientSession createTransactedSession()
                                      throws HornetQException

Creates a transacted session. It is up to the client to commit when sending and acknowledging messages.

Returns:

a transacted ClientSession

Throws:

HornetQException - if an exception occurs while creating the session

See Also:

ClientSession.commit()

createSession

ClientSession createSession()
                            throws HornetQException

Creates a non-transacted session. Message sends and acknowledgements are automatically committed by the session. This does not mean that messages are automatically acknowledged, only that when messages are acknowledged, the session will automatically commit the transaction containing the acknowledgements.

Returns:

a non-transacted ClientSession

Throws:

HornetQException - if an exception occurs while creating the session

createSession

ClientSession createSession(boolean autoCommitSends,
                          boolean autoCommitAcks)
                            throws HornetQException

Creates a session.

Parameters:

autoCommitSends - true to automatically commit message sends, false to commit manually

autoCommitAcks - true to automatically commit message acknowledgement, false to commit manually

Returns:

a ClientSession

Throws:

HornetQException - if an exception occurs while creating the session

createSession

ClientSession createSession(boolean autoCommitSends,
                          boolean autoCommitAcks,
                          int ackBatchSize)
                            throws HornetQException

Creates a session.

Parameters:

autoCommitSends - true to automatically commit message sends, false to commit manually

autoCommitAcks - true to automatically commit message acknowledgement, false to commit manually

ackBatchSize - the batch size of the acknowledgements

Returns:

a ClientSession

Throws:

HornetQException - if an exception occurs while creating the session

createSession

ClientSession createSession(boolean xa,
                          boolean autoCommitSends,
                          boolean autoCommitAcks)
                            throws HornetQException

Creates a session.

Parameters:

xa - whether the session support XA transaction semantic or not

autoCommitSends - true to automatically commit message sends, false to commit manually

autoCommitAcks - true to automatically commit message acknowledgement, false to commit manually

Returns:

a ClientSession

Throws:

HornetQException - if an exception occurs while creating the session

createSession

ClientSession createSession(boolean xa,
                          boolean autoCommitSends,
                          boolean autoCommitAcks,
                          boolean preAcknowledge)
                            throws HornetQException

Creates a session. It is possible to pre-acknowledge messages on the server so that the client can avoid additional network trip to the server to acknowledge messages. While this increase performance, this does not guarantee delivery (as messages can be lost after being pre-acknowledged on the server). Use with caution if your application design permits it.

Parameters:

xa - whether the session support XA transaction semantic or not

autoCommitSends - true to automatically commit message sends, false to commit manually

autoCommitAcks - true to automatically commit message acknowledgement, false to commit manually

preAcknowledge - true to pre-acknowledge messages on the server, false to let the client acknowledge the messages

Returns:

a ClientSession

Throws:

HornetQException - if an exception occurs while creating the session

createSession

ClientSession createSession(String username,
                          String password,
                          boolean xa,
                          boolean autoCommitSends,
                          boolean autoCommitAcks,
                          boolean preAcknowledge,
                          int ackBatchSize)
                            throws HornetQException

Creates an authenticated session. It is possible to pre-acknowledge messages on the server so that the client can avoid additional network trip to the server to acknowledge messages. While this increase performance, this does not guarantee delivery (as messages can be lost after being pre-acknowledged on the server). Use with caution if your application design permits it.

Parameters:

username - the user name

password - the user password

xa - whether the session support XA transaction semantic or not

autoCommitSends - true to automatically commit message sends, false to commit manually

autoCommitAcks - true to automatically commit message acknowledgement, false to commit manually

preAcknowledge - true to pre-acknowledge messages on the server, false to let the client acknowledge the messages

Returns:

a ClientSession

Throws:

HornetQException - if an exception occurs while creating the session

close

void close()

Closes this factory and any session created by it.

Specified by:

close in interface AutoCloseable

isClosed

boolean isClosed()

Returns:

true if the factory is closed, false otherwise.

addFailoverListener

void addFailoverListener(FailoverEventListener listener)

Adds a FailoverEventListener to the session which is notified if a failover event occurs on the session.

Parameters:

listener - the listener to add

removeFailoverListener

boolean removeFailoverListener(FailoverEventListener listener)

Removes a FailoverEventListener to the session.

Parameters:

listener - the listener to remove

Returns:

true if the listener was removed, false else

cleanup

void cleanup()

Opposed to close, will call cleanup only on every created session and children objects.

getServerLocator

ServerLocator getServerLocator()

Returns:

the server locator associated with this session factory

getConnection

CoreRemotingConnection getConnection()

Returns the code connection used by this session factory.

Returns:

the core connection
