If postAdd has been implemented, this method may always return PostCheck.
The default implementation calls preAdd(node)/preAdd(edge) element-wise.
As for most cases this won't be satisfactory a domain-specific implementation should

This pre-check is called on constructing a graph through its companion object.
This pre-check is called on constructing a graph through its companion object.
It must return whether the graph is allowed to be populated with nodes and edges.
The default implementation calls preAdd for each node and edge.
Note that nodes and edges coming from node/edge input streams are not checked.
So when utilizing streams the post check postAdd must be served.

being edge ends may but need not be contained in nodes.
