Class PathTreeModel<C extends ApplicationContext,N extends PathTreeNode>

java.lang.Object

javax.swing.tree.DefaultTreeModel

de.esprit.appsuite.gui.pathtree.PathTreeModel<C,N>

All Implemented Interfaces:

ApplicationObject<C>, Resettable, java.io.Serializable, javax.swing.tree.TreeModel

public class PathTreeModel<C extends ApplicationContext,N extends PathTreeNode>
extends javax.swing.tree.DefaultTreeModel
implements ApplicationObject<C>, Resettable

This TreeModel implementation stores the PathTreeNodes of a file system tree which is watched by a watch-service and thus reflects any changes in the file-system immediately.

Constructor Detail

PathTreeModel

Method Detail

getApplicationContext

public C getApplicationContext()

Specified by:

getApplicationContext in interface ApplicationObject<C extends ApplicationContext>

getRoot

public final N getRoot()

Specified by:

getRoot in interface javax.swing.tree.TreeModel

Overrides:

getRoot in class javax.swing.tree.DefaultTreeModel

getDriver

public PathTreeModelDriver getDriver()

setRoot

public final void setRoot(javax.swing.tree.TreeNode root)

Overrides:

setRoot in class javax.swing.tree.DefaultTreeModel

reset

public final void reset()

Resets the root node of the tree. This collapses the tree and forgets all its children.

Specified by:

reset in interface Resettable

getChild

public PathTreeNode getChild(java.lang.Object parent,
                    int index)

Specified by:

getChild in interface javax.swing.tree.TreeModel

Overrides:

getChild in class javax.swing.tree.DefaultTreeModel

getChildCount

public int getChildCount(java.lang.Object parent)

Specified by:

getChildCount in interface javax.swing.tree.TreeModel

Overrides:

getChildCount in class javax.swing.tree.DefaultTreeModel

isLeaf

public boolean isLeaf(java.lang.Object node)

Specified by:

isLeaf in interface javax.swing.tree.TreeModel

Overrides:

isLeaf in class javax.swing.tree.DefaultTreeModel

getIndexOfChild

public int getIndexOfChild(java.lang.Object parent,
                  java.lang.Object child)

Specified by:

getIndexOfChild in interface javax.swing.tree.TreeModel

Overrides:

getIndexOfChild in class javax.swing.tree.DefaultTreeModel

findPathTreeNode

public final N findPathTreeNode(java.nio.file.Path path)

findPathTreeNode

public final N findPathTreeNode(PathInfo pathInfo)

findTreePath

public final javax.swing.tree.TreePath findTreePath(java.nio.file.Path path)

createPathTreeNode

protected N createPathTreeNode(N parent,
                   PathInfo childPathInfo)

Same as createPathTreeNode(PathTreeNode, PathInfo, Comparator) whereas the Comparator is just overtaken from the parent node.

createPathTreeNode

protected N createPathTreeNode(N parent,
                   PathInfo childPathInfo,
                   java.util.Comparator<PathTreeNode> comparator)

Creates the PathTreeNode to be inserted in the tree model. This method may be overridden to create a subclass instance of PathTreeNode. Note that this method needs to be overridden if a special PathTreeNode is desired.

renamePath

public void renamePath(java.nio.file.Path oldPath,
              java.nio.file.Path newPath)
                throws java.lang.Exception

Throws:

java.lang.Exception
