Class Summary
Class	Description
BasicManagedDataSource	BasicManagedDataSource is an extension of BasicDataSource which creates ManagedConnections.
DataSourceXAConnectionFactory	An implementation of XAConnectionFactory which uses a real XADataSource to obtain connections and XAResources.
LocalXAConnectionFactory	An implementation of XAConnectionFactory which manages non-XA connections in XA transactions.
LocalXAConnectionFactory.LocalXAResource	LocalXAResource is a fake XAResource for non-XA connections.
ManagedConnection<C extends Connection>	ManagedConnection is responsible for managing a database connection in a transactional environment (typically called "Container Managed").
ManagedDataSource<C extends Connection>	The ManagedDataSource is a PoolingDataSource that creates ManagedConnections.
PoolableManagedConnection	PoolableConnection that unregisters from TransactionRegistry on Connection real destroy.
PoolableManagedConnectionFactory	A `PoolableConnectionFactory` that creates `PoolableManagedConnection`s.
TransactionContext	TransactionContext represents the association between a single XAConnectionFactory and a Transaction.
TransactionRegistry	TransactionRegistry tracks Connections and XAResources in a transacted environment for a single XAConnectionFactory.

Package org.apache.commons.dbcp2.managed Description

This package provides support for pooling of ManagedConnections. A managed connection is responsible for managing a database connection in a transactional environment (typically called Container Managed). A managed connection operates like any other connection when no global transaction (a.k.a. XA transaction or JTA Transaction) is in progress. When a global transaction is active a single physical connection to the database is used by all ManagedConnections accessed in the scope of the transaction. Connection sharing means that all data access during a transaction has a consistent view of the database. When the global transaction is committed or rolled back the enlisted connections are committed or rolled back.

This package supports full XADataSources and non-XA data sources using local transaction semantics. non-XA data sources commit and rollback as part of the transaction but are not recoverable in the case of an error because they do not implement the two-phase commit protocol.
