Description: declaration: package: org.apache.tomcat.dbcp.dbcp2.managed, class: LocalXAConnectionFactory

# 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.

  - ### createConnection

    public Connection createConnection() throws SQLException
    Description copied from interface: `XAConnectionFactory`

    Returns:
      a new `Connection`
    Throws:
      `SQLException` - if a database error occurs creating the connection

  - ### getConnectionFactory

    public ConnectionFactory getConnectionFactory()
    Gets the connection factory.
    Returns:
      The connection factory.
    Since:
      2.6.0

  - ### getTransactionRegistry

    public TransactionRegistry getTransactionRegistry()
    Gets the transaction registry.
