Method Detail

emitRecord

void emitRecord(E element,
                org.apache.flink.api.connector.source.SourceOutput<T> output,
                SplitStateT splitState)
         throws Exception

Process and emit the records to the SourceOutput. A few recommendations to the implementation are following:

• The method maybe interrupted in the middle. In that case, the same set of records will be passed to the record emitter again later. The implementation needs to make sure it reades

Parameters:

element - The intermediate element read by the SplitReader.

output - The output to which the final records are emit to.

splitState - The state of the split.

Throws:

Exception
