Class DefaultCatalogTreeManagerXml

java.lang.Object

jmri.jmrit.XmlFile

jmri.jmrit.catalog.configurexml.DefaultCatalogTreeManagerXml

public class DefaultCatalogTreeManagerXml
extends XmlFile

Provides the abstract base and store functionality for configuring the CatalogTreeManager.

Typically, a subclass will just implement the load(Element catalogTree) class, relying on implementation here to load the individual CatalogTree objects.

Method Detail

writeCatalogTrees

public void writeCatalogTrees()
                       throws java.io.IOException

Write out tree values to a file in the user's preferences directory.

Throws:

java.io.IOException - from any I/O issues during write; not handled locally

store

public void store(org.jdom2.Element cat,
                  java.util.Set<CatalogTree> trees)

Default implementation for storing the contents of a CatalogTreeManager.

Parameters:

cat - Element to load with contents

trees - List of contents

storeNode

public void storeNode(org.jdom2.Element parent,
                      CatalogTreeNode node)

Recursively store a CatalogTree.

Parameters:

parent - the element to store node in

node - the root node of the tree

store

public org.jdom2.Element store(java.lang.Object o)

This is invoked as part of the "store all" mechanism, which is not used for these objects. Hence this is implemented to do nothing.

Parameters:

o - the object to store

Returns:

null

readCatalogTrees

public void readCatalogTrees()

load

public boolean load(org.jdom2.Element catalogTrees)

Create a CatalogTreeManager object of the correct class, then register and fill it.

Parameters:

catalogTrees - top level Element to unpack

Returns:

true if successful

loadCatalogTrees

public void loadCatalogTrees(org.jdom2.Element catalogTrees)

Utility method to load the individual CatalogTree objects.

Parameters:

catalogTrees - element containing trees

loadNode

public void loadNode(org.jdom2.Element element,
                     CatalogTreeNode parent,
                     javax.swing.tree.DefaultTreeModel model)

Recursively load a CatalogTree.

Parameters:

element - element containing the node to load

parent - the parent node of the node in element

model - the tree model containing the tree to add the node to
