All Implemented Interfaces:

Parser<RLSCSVResult>, CloseableIterator<RLSCSVResult>, Closeable, AutoCloseable

public class RLSCSVParser
extends Object
implements Parser<RLSCSVResult>

Parses an RLS source file into RLSCSVResult entries.

This class parses an RLS file into RLSCSVResults

Retrieves CSV files from a configuration file inspired from RLS syntax <a href="https://github.com/knowsys/rulewerk/wiki/Rule-syntax-grammar#source-declarations">...</a> Each line of the configuration file defines a CSV file as well as the predicate it defines.
