* execute method that takes an input Record, output
* Record and an InteractionSpec. This method executes the EIS
* function represented by the InteractionSpec and updates the
* output Record
* execute method that takes an input Record and an
* InteractionSpec. This method implementation executes the EIS
* function represented by the InteractionSpec and produces the
* output Record as a return value.
*
* An Interaction instance is created from a Connection and is required
* to maintain its association with the Connection instance. The close method
* releases all resources maintained by the resource adapter for the
* Interaction. The close of an Interaction instance should not close the
* associated Connection instance.
