Package csv.util

Class ObjectReader<T>

java.lang.Object
csv.util.ObjectReader<T>
All Implemented Interfaces:
java.lang.Iterable<T>, java.util.Iterator<T>
public class ObjectReader<T>
extends java.lang.Object
implements java.util.Iterator<T>, java.lang.Iterable<T>
Reads objects from a table.

This class is different to BeanReader as it asks a converter to convert the row.

 // Create an instance of your table reader 
 TableReader tableReader = ...; 
 
 // Get an instance of your row converter
 RowConverter<MyClass> converter = new MyClassConverter();
 
 // Now read from the table stream
 ObjectReader<MyClass> reader = new ObjectReader(tableReader, converter, true);
 Object tableHeader[] = reader.getTableHeader();
 while (reader.hasNext()) {
    MyClass myObject = reader.next();
    
    // do something...
 }
 
 // Close the reader
 reader.close();
