Member Typedef Documentation

typedef _LengthMap LengthMap

The type of the map that stores the edge lengths. It must meet the ReadMap concept.

typedef DagShortestPathDefaultOperationTraits<Value> OperationTraits

It defines the infinity type on the given Value type and the used operation.

Member Function Documentation

static PredMap* createPredMap

(

const _Graph &

graph

)

[inline, static]

This function instantiates a PredMap.

Parameters:

graph

is the graph, to which we would like to define the PredMap.

Todo:

The graph alone may be insufficient for the initialization

static DistMap* createDistMap

(

const _Graph &

graph

)

[inline, static]

This function instantiates a DistMap.

Parameters:

graph

is the graph, to which we would like to define the DistMap
