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

Field Summary

static java.lang.String	BYTESTREAM_PREFIX Prefix on the MIME encoding that indicates that the encoded data is not encoded.
static java.lang.String	GZIP_BYTESTREAM_PREFIX Prefix on the MIME encoding that indicates that the encoded data is encoded with GZIP.

PersistentPropertyDataEncoderImpl()

Method Summary

java.util.List	decodePageChanges(java.lang.String encoded) Takes a string with an encoded set of page changes, and converts it back into a list of PropertyChanges.
java.lang.String	encodePageChanges(java.util.List changes) Encodes a (possibly empty) list of PropertyChanges into a string representation that can later be decoded.
