Method Detail

getDepth

public static int getDepth(javafx.scene.control.TreeItem<?> pTreeItem)

getRoot

public static <T> javafx.scene.control.TreeItem<T> getRoot(javafx.scene.control.TreeItem<?> pItem)

visitorStream

public static <T> Stream<javafx.scene.control.TreeItem<T>> visitorStream(javafx.scene.control.TreeItem<T> pTreeItem)

Stream containing specified tree item and all of its descendants. Depth-first visitor in TreeItemUtil.StreamOrder.ABDC order.

visitorStream

public static <T> Stream<javafx.scene.control.TreeItem<T>> visitorStream(javafx.scene.control.TreeItem<T> pTreeItem,
                                                                         TreeItemUtil.StreamOrder pOrder)

Stream containing specified tree item and all of its descendants. Depth-first visitor.

ancestorObservableList

public static <T> javafx.collections.ObservableList<javafx.scene.control.TreeItem<T>> ancestorObservableList(javafx.scene.control.TreeItem<T> pTreeItem)

ObservableList starting with specified node and ending at root.

descendantObservableList

public static <T> javafx.collections.ObservableList<javafx.scene.control.TreeItem<T>> descendantObservableList(javafx.scene.control.TreeItem<T> pTreeItem)

descendantObservableList

public static <T> javafx.collections.ObservableList<javafx.scene.control.TreeItem<T>> descendantObservableList(javafx.scene.control.TreeItem<T> pTreeItem,
                                                                                                               TreeItemUtil.StreamOrder pStreamOrder)

List containing argument node and all descendants. Automatically updated when children are added/removed. List is in TreeItemUtil.StreamOrder.ABDC order.

visitorStream(TreeItem)

descendantCountProperty

public static <T> javafx.beans.property.ReadOnlyObjectProperty<Integer> descendantCountProperty(javafx.scene.control.TreeItem<T> pTreeItem)

Property providing the count of argument node and all descendants. Count changes are delayed to improve performance and to prevent too frequent updates.

parentIterator

public static <T> Iterator<javafx.scene.control.TreeItem<T>> parentIterator(javafx.scene.control.TreeItem<T> pTreeItem)

Iterator from argument tree item up to and including root tree item.

Parameters:

pTreeItem - First item returned by iterator.

TreeItem.getParent()

isVisible

public static boolean isVisible(javafx.scene.control.TreeItem<?> pTreeItem)

Determines whether all ancestors are expanded.

Returns:

true if all ancestors are expanded.
