Package net.sf.basedb.util.parser

Class LineNoFunction

java.lang.Object
net.sf.basedb.util.parser.LineNoFunction
All Implemented Interfaces:
JepFunction, org.nfunk.jep.function.PostfixMathCommandI
public class LineNoFunction
extends Object
implements JepFunction
Adds a lineNo() function to Jep. The lineNo() function is used with the FlatFileParser to get the current line number. Use the FlatFileParser.getMapper(String) with an argument starting with an equal sign to create a mapper that uses Jep. 
FlatFileParser ffp = ...
Mapper lineNoMapper = ffp.getMapper("=lineNo()");
while (ffp.hasMoreData())
{
        Data data = ffp.nextData();
        int lineNumber = lineNoMapper.getInt(data);
}
