Class DelimitedRecordFormat

java.lang.Object

org.apache.storm.hdfs.bolt.format.DelimitedRecordFormat

All Implemented Interfaces:

Serializable, RecordFormat

public class DelimitedRecordFormat
extends Object
implements RecordFormat

RecordFormat implementation that uses field and record delimiters. By default uses a comma (",") as the field delimiter and a newline ("\n") as the record delimiter.

Also by default, this implementation will output all the field values in the tuple in the order they were declared. To override this behavior, call withFields() to specify which tuple fields to output.
