Method Detail

getConfiguration

OpenJPAConfiguration getConfiguration()

Return the configuration for this factory.

getProperties

Map<String,Object> getProperties()

Return properties describing this runtime.

getSupportedProperties

Set<String> getSupportedProperties()

Return all of the supported properties as a set of keys. If a property has multiple keys, all keys will be returned.

Since:

2.0.0

putUserObject

Object putUserObject(Object key,
                   Object val)

Put the specified key-value pair into the map of user objects.

getUserObject

Object getUserObject(Object key)

Get the value for the specified key from the map of user objects.

newBroker

Broker newBroker()

Return a broker with default settings.

newBroker

Broker newBroker(String user,
               String pass,
               boolean managed,
               int connRetainMode,
               boolean findExisting)

Return a broker using the given credentials and in the given transaction and connection retain mode, optionally finding existing broker in the global transaction.

newBroker

Broker newBroker(String user,
               String pass,
               boolean managed,
               int connRetainMode,
               boolean findExisting,
               String cfName,
               String cf2Name)

Return a new broker using the supplied

• credentials
• transaction management mode
• connectionRetainMode
• connectionFactories

Parameters:

user - Username to use when obtaining a connection. Will be ignored if a connection factory is obtained from JNDI.

pass - Password to use when obtaining a connection. Will be ignored if a connection factory is obtained from JNDI.

managed - Whether managed transactions will be used by this Broker

connRetainMode - ConnectionRetainMode

findExisting - Whether the internal pool of brokers should be used.

cfName - JTA ConnectionFactory to use

cf2Name - Non-JTA ConnectionFactory to use.

Returns:

A Broker which matches the provided criteria.

addLifecycleListener

void addLifecycleListener(Object listener,
                        Class<?>[] classes)

Register a listener for lifecycle-related events on the specified classes. If the classes are null, all events will be propagated to the listener. The listener will be passed on to all new brokers.

Since:

0.3.3

removeLifecycleListener

void removeLifecycleListener(Object listener)

Remove a listener for lifecycle-related events.

Since:

0.3.3

addTransactionListener

void addTransactionListener(Object listener)

Register a listener for transaction-related events on the specified classes. It will be registered with all Brokers created from this instance moving forward.

Since:

1.0.0

removeTransactionListener

void removeTransactionListener(Object listener)

Remove a listener for transaction-related events. It will no longer be registered with new Brokers created from this instance.

Since:

1.0.0

close

void close()

Close the factory.

Specified by:

close in interface Closeable

isClosed

boolean isClosed()

Returns true if this broker factory is closed.

lock

void lock()

Synchronizes on an internal lock.

unlock

void unlock()

Release the internal lock.

assertOpen

void assertOpen()

assert that this broker is open. If the broker has been closed an IllegalStateException will be thrown with information on when the broker was closed.

postCreationCallback

void postCreationCallback()

This method is invoked AFTER a BrokerFactory has been instantiated.
