Examples of DataSqueezer

org.apache.tapestry.services.DataSqueezer
Lightweight serialization used to encode values into strings that are stored in query parameters and hidden fields. @author Howard Lewis Ship @since 4.0
org.apache.tapestry.util.io.DataSqueezer
A class used to convert arbitrary objects to Strings and back. This has particular uses involving HTTP URLs and Cookies. @author Howard Lewis Ship @version $Id: DataSqueezer.java 243791 2004-02-19 17:38:13Z hlship $
