org.springframework.jca.cci.core.RecordExtractor<T> |
Known Indirect Subclasses |
Callback interface for extracting a result object from a CCI Record instance.
Used for output object creation in CciTemplate. Alternatively, output Records can also be returned to client code as-is. In case of a CCI ResultSet as execution result, you will almost always want to implement a RecordExtractor, to be able to read the ResultSet in a managed fashion, with the CCI Connection still open while reading the ResultSet.
Implementations of this interface perform the actual work of extracting results, but don't need to worry about exception handling. ResourceExceptions will be caught and handled correctly by the CciTemplate class.
