Class BeanConvertor

java.lang.Object
  org.apache.cocoon.forms.datatype.convertor.BeanConvertor

All Implemented Interfaces:

Convertor

public class BeanConvertor
extends Object
implements Convertor

Converts String representation of beans to bean instances and vice versa.

Sometimes the toString() method doesn't give a good representation of a Java Bean suited for selection list IDs. For this an optional <fd:id-path>jx-path</fd:id-path> attribute can be specified to have this convertor to use a different string representation.
