Class CSVInputReader

java.lang.Object

de.ipcon.db.importer.CSVInputReader

All Implemented Interfaces:

InputReaderI, java.io.Closeable, java.lang.AutoCloseable, java.util.Iterator<DataSetI>

public class CSVInputReader
extends java.lang.Object
implements InputReaderI, java.io.Closeable, java.util.Iterator<DataSetI>

This class reads a given data stream line by line, parses them into field values according to and via the given CSVConfiguration and makes these available as DataSetIs. FIXME See de/ipcon/db/BOEnvironmentBuilder javadoc for a very brief explanation how these classes are used (for initialdata import).

Method Summary

Modifier and Type	Method and Description
void	close()
java.lang.String	getLocationInfo()
boolean	hasNext()
DataSetI	next() Reads the next line from the input, parses it, converts the string field values into typed values (according to and via the CSVConfiguration) and returns a DataSetI with all the values.
static java.lang.String[]	splitLine(java.lang.String line, java.lang.String _enclosingChar, java.lang.String _separator, int columnToSkip) Helper method to split a given line (String) into fields, in a separate method basically only so we could easily write a JUnit test.
