Class DefaultTreeModel<T>

java.lang.Object
  extended by org.apache.tapestry5.tree.DefaultTreeModel<T>
Type Parameters:
T -
All Implemented Interfaces:
TreeModel<T>

public class DefaultTreeModel<T>
extends Object
implements TreeModel<T>

A default implementation of TreeModel that starts with a ValueEncoder (for the element to string conversion), a TreeModelAdapter, and a list of root nodes.

This implementation is not thread safe.

Since:
5.3

Constructor Summary
DefaultTreeModel(ValueEncoder<T> encoder, TreeModelAdapter<T> adapter, List<T> roots)
          Standard constructor.
DefaultTreeModel(ValueEncoder<T> encoder, TreeModelAdapter<T> adapter, T root)
          Creates a new model starting from a single root element.
 
Method Summary
 TreeNode<T> find(T element)
          Recursively searches from the root nodes to find the tree node that matches the provided element.
 TreeNode<T> getById(String id)
          Locates a node in the tree by its unique id.
 List<TreeNode<T>> getRootNodes()
          Returns the node or nodes that are the top level of the tree.
