@FunctionalInterface interface InteractionCallback<T : Any>
Generic callback interface for code that operates on a CCI Interaction. Allows to execute any number of operations on a single Interaction, for example a single execute call or repeated execute calls with varying parameters.
This is particularly useful for delegating to existing data access code that expects an Interaction to work on and throws ResourceException. For newly written code, it is strongly recommended to use CciTemplate's more specific execute variants.

abstract fun doInInteraction(interaction: Interaction, connectionFactory: ConnectionFactory): T
Gets called by If called without a thread-bound CCI transaction (initiated by CciLocalTransactionManager), the code will simply get executed on the CCI Interaction with its transactional semantics. If CciTemplate is configured to use a JTA-aware ConnectionFactory, the CCI Interaction 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 |
