C# Class Smrf.NodeXL.Layouts.FruchtermanReingoldVertexInfo

Stores information calculated by FruchtermanReingoldLayout for one vertex.

FruchtermanReingoldLayout calculates several pieces of information about each vertex in the graph being laid out. Instead of storing each piece of information in a separate vertex metadata key, which would require multiple key lookups and inefficient boxing and unboxing of value types, it stores all the information for the vertex in one instance of type FruchtermanReingoldVertexInfo and stores the instance in the vertex's Tag.

All data is exposed as public fields instead of properties. That's because the method in FruchtermanReingoldLayout that calculates repulsive forces accesses the data repeatedly in an O(V-squared) loop, and property getters are much slower than direct field accesses.
