Interface UiWidgetAbstractTree.UiTreeModel<NODE>

Type Parameters:

NODE - is the generic type of the tree-nodes of this model.

All Known Subinterfaces:

UiWidgetAbstractTree.UiTreeModelMutable<NODE>

All Known Implementing Classes:

UiTreeNodeModel

Enclosing interface:

UiWidgetAbstractTree<NODE>

public static interface UiWidgetAbstractTree.UiTreeModel<NODE>

This is the interface for the model (adapter) for a UiWidgetTree. If the tree structure should be editable for the end-user you need to implement UiWidgetAbstractTree.UiTreeModelMutable. However, modification of the tree node data is still possible if the tree is editable.

Method Summary

Modifier and Type	Method and Description
List<NODE>	getChildren(NODE node) This method gets the children of the given tree-node.
void	getChildrenAsync(NODE node, Consumer<List<NODE>> callback) This method gets the children of the given tree-node asynchronously.

Method Detail

getChildren

List<NODE> getChildren(NODE node)

This method gets the children of the given tree-node.

Parameters:

node - the tree-node for which the children are requested.

Returns:

the List of child-nodes or null if NOT available and asynchronous loading is required.

getChildrenAsync

void getChildrenAsync(NODE node,
                      Consumer<List<NODE>> callback)

This method gets the children of the given tree-node asynchronously.

Parameters:

node - the tree-node for which the children are requested.

callback - is the Consumer that will be called when the children are available. Maybe null if only loading shall be triggered.
