commit

public void commit()

Description copied from interface: TopicMapTransactionIF

PUBLIC: Commits the transaction. The changes made are written to the persistent store.

The transaction will resume after the commit meaning that the objects retrieved through is still usable after the commit.

Specified by:

commit in interface TopicMapTransactionIF

Overrides:

commit in class AbstractTopicMapTransaction

abort

public void abort()

Description copied from interface: TopicMapTransactionIF

PUBLIC: Aborts the transaction; all changes made inside the transaction are rolled back.

The transaction will resume after the abort meaning that the objects retrieved through is still usable after the abort, but their state has been reverted to the state in the persistent store.

Specified by:

abort in interface TopicMapTransactionIF

Overrides:

abort in class AbstractTopicMapTransaction

abort

public void abort(boolean invalidate)

Overrides:

abort in class AbstractTopicMapTransaction

validate

public boolean validate()

Specified by:

validate in class AbstractTopicMapTransaction

createNested

public TopicMapTransactionIF createNested()

Overrides:

createNested in class AbstractTopicMapTransaction

getTransaction

public TransactionIF getTransaction()

INTERNAL: Returns the proxy transaction used by the topic map transaction.

getTopicMap

public TopicMapIF getTopicMap()

Description copied from interface: TopicMapTransactionIF

PUBLIC: Gets the topic map that is accessible through the transaction.

Specified by:

getTopicMap in interface TopicMapTransactionIF

Overrides:

getTopicMap in class AbstractTopicMapTransaction

Returns:

The topic map in the transaction; an object implementing TopicMapIF.

addListener

public void addListener(EventListenerIF listener,
 String event)

Description copied from interface: EventManagerIF

INTERNAL: Register the listener as a listener for the event.

Specified by:
