## Member Typedef Documentation

typedef LEN LengthMap

The type of the map that stores the arc lengths. It must conform to the ReadMap concept.

typedef BellmanFordDefaultOperationTraits<Value> OperationTraits

It defines the used operations and the infinity value for the given `Value` type.

This function instantiates a DistMap.

Parameters

  g | is the digraph to which we would like to define the DistMap.
