Hierarchical data is data already in a structure of parent and child data items.
The HierarchicalData class provides a default implementation for
accessing and manipulating data for use in controls such as the AdvancedDataGrid control.
To configure the AdvancedDataGrid control to display hierarchical data,
you pass to the dataProvider property an instance of the HierarchicalData class.
This implementation handles E4X, XML, and Object nodes in similar but different
ways. See each method description for details on how the method
accesses values in nodes of various types.
Indicates the field name to be used to detect children objects in
a data item.
By default, all subnodes are considered as children for
XML data, and the children property is used for the Object data type.
This is helpful in adapting to a data format that uses custom data fields
to represent children.
