Interface TreeItemData<T>

Type Parameters:

T - the type of the data

All Known Implementing Classes:

TreeItemImpl.TreeItemDataImpl

public interface TreeItemData<T>

This interface defines the type of a TreeItem for a ModularTreeView. It provides access to the actual typed data of each node, as well as to the contributions which apply to that node, and the item data of the parent.

Method Summary

Modifier and Type	Method and Description
java.util.stream.Stream<TreeContribution<? super T>>	contributions() Get all the contributions which should be applied to a tree item, in order from most to least specific.
<U extends TreeContribution<? super T>> java.util.stream.Stream<U>	contributions(TypeToken<U> type) Get all contributions which should be applied to a tree item and which match a given type, in order from most to least specific.
default T	data()
java.util.Optional<TreeItemData<?>>	parent()
void	refresh(boolean recursive) Refresh the tree cell associated with this tree item.
ModularTreeView	treeView()
default TypeToken<?>	type()
TypedObject<T>	typedData()
