readImpl
Description copied from class:DataReaderOverridden by subclasses to read the next record from thisDataReader. The default implementation ofDataReader.read()now insures that this method will not be called again after it returns anull.If no record is available,
nullwill be returned.Contract for subclasses (see also
docs/authoring/DataReader.md):- Return
nullexactly once to signal end-of-stream. - Do not call this method directly —
DataReader.read()is the template method that wraps exceptions, increments the record count, and tracks lineage. - Do not call
DataEndpoint.incrementRecordCount()here;DataReader.read()already does. - Throw raw exceptions;
DataReader.read()wraps them viaexception(throwable).
- Specified by:
readImplin classDataReader- Throws:
Throwable
- Return
-
open
Description copied from class:DataEndpointMakes this endpoint ready for reading or writing.- Overrides:
openin classIntegrationReader- Throws:
DataException
-
close
Description copied from class:DataEndpointIndicates that this endpoint has finished reading or writing.- Overrides:
closein classDataEndpoint- Throws:
DataException
-
addExceptionProperties
Description copied from class:EndpointAdds this endpoint's current state to aDataException. Since this method is called whenever an exception is thrown, subclasses should override it to add their specific information.- Overrides:
