arccore.graph weighted edge traverse enhancement #4
Description
I just release v0.1.9 crescent with support for weigted edge BFT/DFT.
In hindsight I missed an rather obvious usability enhanancement.
Currently, to enable edge-weighted traversal you need to add getEdgeWeight and compareEdgeWeights callback function definitions to your visitor object.
But, in the vast majority of cases the developer-defined edge weight will a value of a type that is comparable via standard less-than and greater-than operators (e.g. string, numeric value).
So, we should allow developers to specify on getEdgeWeight to enable edge-weight traversal feature. And, allow compareEdgeWeight to be left unspecified in order to use default comparison operator provided by graph library (should be sufficient for 80% of use cases).
