Detailed Description
RowReader interface.
Common interface for those readers which get the data as an string array.
It works as follows: perform as many read operations as necessary and call close once at the end. Once close is called no more read operations can be executed.
Check out the 'Data import' section in the SPARKSEE User Manual for more details on this.
