GetCost Concept Reference
Concepts

Definition

The concept GetCost describes the requirements for the policy function object which gets the collapse cost of an edge.

The cost returned is a boost::optional value (i.e. it can be absent). An absent cost indicates that the edge should not be collapsed. This could be the result of a computational limitation (such as overflow), or can be intentionally returned to prevent the edge from being collapsed.
