jmri.jmrit.revhistory.configurexml
Class FileHistoryXml

java.lang.Object
  jmri.configurexml.AbstractXmlAdapter
      jmri.jmrit.revhistory.configurexml.FileHistoryXml

All Implemented Interfaces:

XmlAdapter

public class FileHistoryXml
extends AbstractXmlAdapter

Load/Store FileHistory objects.

This interacts somewhat differently with the ConfigureXML system. FileHistory objects are _not_ registed with the manager, but rather handled explicitly by them. The "load()" method is therefore a null-op here.

Method Detail

load

public boolean load(Element e)
             throws Exception

Usual configurexml method, this one doesn't do anything because the content is explicitly loaded from the file

Parameters:

e - Top-level XML element containing the description

Returns:

true if successful

Throws:

Exception - when a error prevents creating the objects as as required by the input XML.

loadDirectly

public boolean loadDirectly(Element e)
                     throws Exception

Load RevHistory from an element.

If no RevHistory already present in InstanceManager, creates one and adds this.

Then adds, instead of replacing, the history information

Throws:

Exception

loadFileHistory

public static FileHistory loadFileHistory(Element e)

loadOperation

public static void loadOperation(FileHistory r,
                                 Element e)

load

public void load(Element e,
                 Object o)
          throws Exception

Create a set of configured objects from their XML description, using an auxiliary object.

For example, the auxilary object o might be a manager or GUI of some type that needs to be informed as each object is created.

Parameters:

e - Top-level XML element containing the description

o - Implementation-specific Object needed for the conversion

Throws:

Exception - when a error prevents creating the objects as as required by the input XML.

store

public Element store(Object o)

Store the

Parameters:

o - The object to be recorded. Specific XmlAdapter implementations will require this to be of a specific type; that binding is done in ConfigXmlManager.

Returns:

The XML representation Element

storeDirectly

public static Element storeDirectly(Object o)
