    This method should be implemented by those row readers which reads fields in the consecutive positions from a CassandraRow.

    This method should be implemented by those row readers which reads fields in the consecutive positions from a CassandraRow. When a row reader implements it so that it returns a non-empty, it denotes the number of columns this reader moves the column cursor forward for compound row readers (such as com.datastax.spark.connector.rdd.reader.KeyValueRowReader).
