Class PersistentPropertyDataEncoderImpl

java.lang.Object

org.apache.tapestry.record.PersistentPropertyDataEncoderImpl

All Implemented Interfaces:

PersistentPropertyDataEncoder

public class PersistentPropertyDataEncoderImpl
extends java.lang.Object
implements PersistentPropertyDataEncoder

Responsible for converting lists of PropertyChanges back and forth to a URL safe encoded string.

A possible improvement would be to encode the binary data with encryption both on and off, and select the shortest (prefixing with a character that identifies whether encryption should be used to decode).

Since:

4.0
