Interface ClientSessionFactory

All Superinterfaces:

AutoCloseable

public interface ClientSessionFactory
extends AutoCloseable

A ClientSessionFactory is the entry point to create and configure ActiveMQ Artemis 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 an IllegalStateException.

void	cleanup()	Opposed to close, will call cleanup only on every created session and children objects.
void	close()	Closes this factory and any session created by it.
ClientSession	createSession()	Creates a non-transacted session.

Method Detail

createXASession

ClientSession createXASession()
                       throws ActiveMQException

Creates a session with XA transaction semantics.

Returns:

a ClientSession with XA transaction semantics

Throws:

ActiveMQException - if an exception occurs while creating the session

createTransactedSession

ClientSession createTransactedSession()
                               throws ActiveMQException

Creates a transacted session.

It is up to the client to commit when sending and acknowledging messages.

Returns:

a transacted ClientSession

Throws:

ActiveMQException - if an exception occurs while creating the session

See Also:

ClientSession.commit()

createSession

ClientSession createSession()
                     throws ActiveMQException

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:

ActiveMQException - if an exception occurs while creating the session

createSession

ClientSession createSession(boolean autoCommitSends,
                            boolean autoCommitAcks)
                     throws ActiveMQException

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:

ActiveMQException - if an exception occurs while creating the session

createSession

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

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:

ActiveMQException - if an exception occurs while creating the session

createSession

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

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:

ActiveMQException - if an exception occurs while creating the session

createSession

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

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:

ActiveMQException - if an exception occurs while creating the session

createSession

ClientSession createSession(String username,
                            String password,
                            boolean xa,
                            boolean autoCommitSends,
                            boolean autoCommitAcks,
                            boolean preAcknowledge,
