<p><strong>Parent-Child Node (Vertex) Issues</strong> </p>
|
|||
|
|
|
|||
|
|
<hr />
|
|||
|
|
|

|
<p> </p>
|
|||
|
|
|
|||
|
|
<p>All the operators are designed to work consistently with parent and
|
|||
|
|
child nodes(if they exist) consistently. Operators exist for getting the
|
|||
|
|
parent of a vertex, edge and face. The parent edge/face of a edge/face
|
|||
|
|
is constructed from the parents of its component vertices. Operators
|
|||
|
|
also exist for obtaining the child vertices/edges/faces of
|
|||
|
|
vertices/edges/faces.</p>
|
|||
|
|
|
|||
|
|
<p>The upward and downward adjacency information is designed to be returned
|
|||
|
|
in a consistent manner as described below. If upward adjacency
|
|||
|
|
information is requested for a child entity then only those higher order
|
|||
|
|
entities connected to the child will be returned. On the other hand, if
|
|||
|
|
it is requested for a parent, upward adjacency information from all its
|
|||
|
|
children will be consolidated and returned. For example, if regions of a
|
|||
|
|
child vertex (node) are requested, then only the regions classified in
|
|||
|
|
that model region will be returned. On the other hand if one wants all
|
|||
|
|
the regions in all model regions connected to the node, one should get
|
|||
|
|
the parent of the vertex and ask for the regions connected to the parent
|
|||
|
|
vertex. The behavior of downward adjacency information queries is
|
|||
|
|
determined by the type of entity and how it is constructed. Asking for
|
|||
|
|
the nodes of a vertex will return only the child nodes if any of the
|
|||
|
|
nodes are on an interface. Parent faces and edges on an interface will
|
|||
|
|
return parent nodes and child faces and edges on an interface will
|
|||
|
|
return child nodes. <em>Lastly, if the entity is not on an interface, it is
|
|||
|
|
its own parent or its own child.</em>
