Constructor Detail

ConnectionFactoryImpl

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

Constructor.

Parameters:

storeMgr - Store Manager

resourceName - either tx or 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

initialiseDataSources

protected void initialiseDataSources()

Method to initialise the DataSource(s) used by this ConnectionFactory. Only invoked when the request for the first connection comes in.

createManagedConnection

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

Method to create a new ManagedConnection.

Parameters:

ec - the object that is bound the connection during its lifecycle (if for a PM/EM operation)

options - Options for creating the connection (optional)

Returns:

The ManagedConnection

calculatePoolingType

protected static String calculatePoolingType(org.datanucleus.store.StoreManager storeMgr,
                                             String requiredPoolingType)

Method to set the connection pooling type (if any). Tries to use any user-provided value if possible, otherwise will fallback to something available in the CLASSPATH (if any), else use the builtin DBCP.

Parameters:

storeMgr - Store Manager

requiredPoolingType - Pooling type requested by the user

Returns:

Pooling type to use (name of a pool type)
