Class FileStreamStrategy

java.lang.Object

com.thoughtworks.xstream.persistence.AbstractFilePersistenceStrategy

com.thoughtworks.xstream.persistence.FileStreamStrategy

All Implemented Interfaces:

PersistenceStrategy, StreamStrategy

Deprecated.

As of 1.3.1, use FilePersistenceStrategy

public class FileStreamStrategy
extends AbstractFilePersistenceStrategy
implements StreamStrategy

PersistenceStrategy to assign string based keys to objects persisted in files. The file naming strategy is based on the key's type name and its toString method. It escapes non digit, non a-z and A-Z characters. In order to change the escaping/unescaping algorithm, simply extend this class and rewrite its getName/extractKey methods. Note, this implementation silently implies that the keys actually are Strings, since the keys will be turned into string keys at deserialization time.
