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