Class SimpleTreePresentationModel<N>

java.lang.Object

org.jhotdraw8.fxbase.tree.AbstractTreePresentationModel<N>

org.jhotdraw8.fxbase.tree.SimpleTreePresentationModel<N>

Type Parameters:

N - the node type

All Implemented Interfaces:

TreePresentationModel<N>

public class SimpleTreePresentationModel<N>
extends AbstractTreePresentationModel<N>

This model can be used to present a TreeModel in a TreeView or a TreeTableView.

Maps TreeModel to a TreeItem<E> hierarchy.

Note: for performance reasons we do not expand the tree nodes by default.

Constructor Details

SimpleTreePresentationModel

public SimpleTreePresentationModel(Supplier<Map<N,javafx.scene.control.TreeItem<N>>> mapFactory)

Creates a new instance.

Parameters:

mapFactory - used to create a map which maps from nodes of type N to javafx.scene.control.TreeItem<N>. For best performance, try to provide an IdentityHashMap here.

Method Details

getRoot

public javafx.scene.control.TreeItem<N> getRoot()

getTreeItem

public javafx.scene.control.TreeItem<N> getTreeItem(N f)

Description copied from interface: TreePresentationModel

Returns the tree item associated to the specified node.

Parameters:

f - the node value

Returns:

a TreeItem. Returns null if no tree item has been associated to the node because the tree is not expanded yet.
