Class EventSessionFactory

java.lang.Object
  com.gigaspaces.events.EventSessionFactory

public class EventSessionFactory
extends Object

the EventSessionFactory is a static service class that creates EventSession objects.
there are two types of EventSession that can be created:
1. DataEventSession - for handling data events
2. AddminEventSession - for handling administrative events

the EventSessionFactory is associated with a space and is required in order to create a factory.
once a factory has been created, it can be used to create sessions.
every session is configured according to an EventSessionConfig object and is bounded to a transaction.

the following code example shows how to create a session from a factory
and register a listener to it.
IJSpace space = SpaceFinder.find(spaceURL);
EventSessionFactory factory = EventSessionFactory.getFactory(space);
EventSessionConfig config = new EventSessionConfig();
config.setFifo(true);
config.setBatch(100, 20000); // size = 100 , time = 20000ms

DataEventSession session = factory.newDataEventSession(config, tx);
session.addListener(new MyEntry(), new MyListener(), Lease.FOREVER, null, null, NotifyActionType.NOTIFY_ALL);

Method Detail

getFactory

public static EventSessionFactory getFactory(IJSpace space)

Retrieves the EventSessionFactory according to the space.

Parameters:

space - the associated space

Returns:

the related factory.

newDataSession

public static DataEventSession newDataSession(IJSpace space,
                                              Transaction tx,
                                              String schemaName)
                                       throws IOException

creates a new DataEventSession bounded to the specified space, specified transaction
and a predefined configuration schema name.

Parameters:

space - the bounded space

tx - the bounded transaction. NULL if no transaction is needed.

schemaName - the name of the predefined configuration schema

Returns:

the DataEventSession

Throws:

IOException - when schema name is invalid or when connection to the space fails.

newDataEventSession

public DataEventSession newDataEventSession(EventSessionConfig config,
                                            Transaction tx)
                                     throws RemoteException

creates a new DataEventSession bounded to the specified transaction,
according to the configuration object.

Parameters:

config - the set of configuration params used to configure the session.

tx - the bounded transaction. NULL if no transaction is needed.

Returns:

the newly created DataEventSession.

Throws:

RemoteException - when connection to the space fails.

newDataEventSession

public DataEventSession newDataEventSession()
                                     throws RemoteException

creates a new DataEventSession according to the configuration object. The method creates default configuration of EventSessionConfig with null transaction

Returns:

the newly created DataEventSession.

Throws:

RemoteException - when connection to the space fails.
