org.apache.tomcat.dbcp.dbcp2.managed

## Interface XAConnectionFactory

- All Superinterfaces:
    ConnectionFactory
  All Known Implementing Classes:
    DataSourceXAConnectionFactory, LocalXAConnectionFactory

      public interface XAConnectionFactory
      extends ConnectionFactory

  XAConnectionFactory is an extension of ConnectionFactory used to create connections in a transaction managed environment. The XAConnectionFactory operates like a normal ConnectionFactory except a TransactionRegistry is provided from which the XAResource for a connection can be obtained. This allows the existing DBCP pool code to work with XAConnections and gives a the ManagedConnection a way to enlist a connection in the transaction.
  Since:
    2.0
