See my portfolio for information on the Document Builder project that used the Query Tree component.
The Nodes class is a simple subclass of Collection(Of T) for the Node objects. It overloads the item property so callers can look up a node by name.
Namespace NACS.Data.QueryTree
Public Class Nodes
Inherits System.Collections.ObjectModel.Collection(Of Node)
Private m_oParent As Node = Nothing
Public Property Parent() As Node
Get
Return m_oParent
End Get
Friend Set(ByVal oParent As Node)
m_oParent = oParent
End Set
End Property
Public Overloads ReadOnly Property Item(ByVal sName As String) As Node
Get
For Each oNode As Node In Me
If oNode.Name.Equals(sName) Then
Return oNode
End If
Next
Throw New IndexOutOfRangeException
End Get
End Property
End Class
End Namespace
