示例1: testTreeData
public void testTreeData()
{
List<Node> nodes = getNodesAll();
Tree<Node> tree = new Tree<Node>( nodes );
// GetById
INode node = tree.GetById( 13 );
Assert.IsNotNull( node );
Assert.AreEqual( "node13", node.Name );
INode nullNode = tree.GetById( 9999 );
Assert.IsNull( nullNode );
// GetParent
INode parent = tree.GetParent( node.Id );
Assert.IsNotNull( parent );
Assert.AreEqual( 5, parent.Id );
// GetDepth
Assert.AreEqual( 0, tree.GetDepth( 2 ) );
Assert.AreEqual( 1, tree.GetDepth( 7 ) );
Assert.AreEqual( 2, tree.GetDepth( 13 ) );
Assert.AreEqual( 2, tree.GetDepth( 14 ) );
// GetPath
List<Node> path = tree.GetPath( 13 );
Assert.AreEqual( 3, path.Count );
Assert.AreEqual( 1, path[0].Id );
Assert.AreEqual( 5, path[1].Id );
Assert.AreEqual( 13, path[2].Id );
// GetChildren
Assert.AreEqual( 0, tree.GetChildren( 4 ).Count );
Assert.AreEqual( 0, tree.GetChildren( 7 ).Count );
List<Node> children = tree.GetChildren( 5 );
Assert.AreEqual( 3, children.Count );
Assert.AreEqual( 13, children[0].Id );
Assert.AreEqual( 14, children[1].Id );
Assert.AreEqual( 15, children[2].Id );
// GetRoots
List<Node> roots = tree.GetRoots();
Assert.AreEqual( 3, roots.Count );
Assert.AreEqual( 1, roots[0].Id );
Assert.AreEqual( 2, roots[1].Id );
Assert.AreEqual( 3, roots[2].Id );
