Interface ConnectionCallback<T>

    • Method Detail

      • doInConnection

        T doInConnection(Connection connection,
                                   ConnectionFactory connectionFactory)
                            throws ResourceException,
        Gets called by CciTemplate.execute with an active CCI Connection. Does not need to care about activating or closing the Connection, or handling transactions.

        If called without a thread-bound CCI transaction (initiated by CciLocalTransactionManager), the code will simply get executed on the CCI Connection with its transactional semantics. If CciTemplate is configured to use a JTA-aware ConnectionFactory, the CCI Connection and thus the callback code will be transactional if a JTA transaction is active.

        Allows for returning a result object created within the callback, i.e. a domain object or a collection of domain objects. Note that there's special support for single step actions: see the CciTemplate.execute variants. A thrown RuntimeException is treated as application exception: it gets propagated to the caller of the template.

        connection - active CCI Connection
        connectionFactory - the CCI ConnectionFactory that the Connection was created with (gives access to RecordFactory and ResourceAdapterMetaData)
        a result object, or null if none
        ResourceException - if thrown by a CCI method, to be auto-converted to a DataAccessException
        java.sql.SQLException - if thrown by a ResultSet method, to be auto-converted to a DataAccessException
        DataAccessException - in case of custom exceptions
