Constructor Detail

ConnectionFactoryImpl

public ConnectionFactoryImpl(org.datanucleus.store.StoreManager storeMgr,
                             String resourceType)

Constructor.

Parameters:

storeMgr - Store Manager

resourceType - Type of resource (tx, nontx)

Method Detail

close

public void close()

Specified by:

close in interface org.datanucleus.store.connection.ConnectionFactory

Overrides:

close in class org.datanucleus.store.connection.AbstractConnectionFactory

createManagedConnection

public org.datanucleus.store.connection.ManagedConnection createManagedConnection(org.datanucleus.ExecutionContext ec,
                                                                                  Map options)

Obtain a connection from the Factory. The connection will be enlisted within the transaction associated to the ExecutionContext. Note that MongoDB doesn't have a "transaction" as such, so commit/rollback don't apply.

Parameters:

ec - the pool that is bound the connection during its lifecycle (or null)

options - Options for creating the connection

Returns:

the ManagedConnection
