Class FileStreamStrategy

java.lang.Object
  edu.internet2.middleware.grouperClientExt.com.thoughtworks.xstream.persistence.FileStreamStrategy

All Implemented Interfaces:

StreamStrategy

public class FileStreamStrategy
extends Object
implements StreamStrategy

The default naming strategy is based on the key's toString method and escapes non digit, non a-z, A-Z characters. In order to change the escaping/unescaping algorithm, simply extend this class and rewrite its getName/extractKey methods.
