## Class LocalXAConnectionFactory

- java.lang.Object
- - org.apache.tomcat.dbcp.dbcp2.managed.LocalXAConnectionFactory

- All Implemented Interfaces:
    ConnectionFactory, XAConnectionFactory

      public class LocalXAConnectionFactory
      extends Object
      implements XAConnectionFactory

  An implementation of XAConnectionFactory which manages non-XA connections in XA transactions. A non-XA connection commits and rolls back as part of the XA transaction, but is not recoverable since the connection does not implement the 2-phase protocol.
  Since:
    2.0

    - #### LocalXAConnectionFactory

          public LocalXAConnectionFactory(TransactionManager transactionManager,
                                          ConnectionFactory connectionFactory)

      Creates an LocalXAConnectionFactory which uses the specified connection factory to create database connections. The connections are enlisted into transactions using the specified transaction manager.
      Parameters:
        `transactionManager` - the transaction manager in which connections will be enlisted
        `connectionFactory` - the connection factory from which connections will be retrieved

    - #### LocalXAConnectionFactory

          public LocalXAConnectionFactory(TransactionManager transactionManager,
                                          TransactionSynchronizationRegistry transactionSynchronizationRegistry,
                                          ConnectionFactory connectionFactory)

      Creates an LocalXAConnectionFactory which uses the specified connection factory to create database connections. The connections are enlisted into transactions using the specified transaction manager.
      Parameters:
        `transactionManager` - the transaction manager in which connections will be enlisted
        `transactionSynchronizationRegistry` - the optional TSR to register synchronizations with
        `connectionFactory` - the connection factory from which connections will be retrieved

        2.8.0

  - ### Method Detail

    - #### createConnection

          public Connection createConnection()
                                      throws SQLException

      Description copied from interface: `XAConnectionFactory`
      Create a new `Connection` in an implementation specific fashion.

      An implementation can assume that the caller of this will wrap the connection in a proxy that protects access to the setAutoCommit, commit and rollback when enrolled in a XA transaction.

      Specified by:
        `createConnection` in interface `ConnectionFactory`
      Specified by:
        `createConnection` in interface `XAConnectionFactory`
      Returns:
        a new `Connection`
      Throws:
        `SQLException` - if a database error occurs creating the connection

    - #### getConnectionFactory

          public ConnectionFactory getConnectionFactory()

      Returns:
        The connection factory.
      Since:
        2.6.0

    - #### getTransactionRegistry

          public TransactionRegistry getTransactionRegistry()

      Description copied from interface: `XAConnectionFactory`
      Gets the TransactionRegistry for this connection factory which contains a the XAResource for every connection created by this factory.
      Specified by:
        `getTransactionRegistry` in interface `XAConnectionFactory`
      Returns:
        the transaction registry for this connection factory
