T
- The type of the wrapped data of the tree node.public abstract class AbstractTreeModel<T> extends java.lang.Object implements TreeModel<T>
TreeModel
. Implementors basically only need to implement createChildren()
wherein a concrete instance of the desired underlying Collection
is returned.ListTreeModel
