Class HandledFile

java.lang.Object

org.silverpeas.core.process.io.file.HandledFile

public class HandledFile
extends Object

This class permits to manipulate files (read/write/delete/...) into transactional processes. It encapsulates a FileHandler instance and knows the root path repository into that it have to work. FileHandler.getHandledFile method has to be called to obtain a HandledFile instance. With HandledFile instance, file manipulations are easier and lighter due to the hiding of internal mechanism.
