Detailed Description

Description:: This class represents an entry in a GenericHierarchy. All methods of the class are implemented by the system.

Data Members:: int data;

This is the polygon number. For example a donut shape will have polygon 0 and polygon 1. This is an index into the list of polygons for the shape.

int children;

Number of children of this entry.

HierarchyEntry *parent;

Points to the parent entry.

HierarchyEntry *sibling;

Points to the first sibling.

HierarchyEntry *child;

Points to the first child.

MSTR sortKey;

The sort key. This is used internally by the hierarchy so that it can determine whether two hierarchies are compatible. Developers shouldn't alter this value.

Constructor & Destructor Documentation

UtilExport HierarchyEntry ( )

Parameters:: int d

The value for data. This is the polygon number.

HierarchyEntry *p

The parent pointer is initialized to this value.

HierarchyEntry *s

The sibling pointer is initialized to this value.

UtilExport int HierarchyLevel ( )

Remarks:: Returns the level in the hierarchy this entry represents. This is the number of parents this item has. The root level is not counted.

UtilExport void AddChild ( int d )

Parameters:: int d

The data value of the child. This is the polygon number.

UtilExport int GetChild ( int index )

Returns:: The specified child of this entry. If the specified index is greater than or equal to the number of children INVALID_HIERARCHY is returned.
