Detailed Description

Define Documentation

#define AT_SUCCESS   0

Create and maintain a graph and find shortest paths. The function was succesful.

#define AT_ILLEGAL_VALUE   -1

You provided an illegal value for one or more of the parameters.

#define AT_EDGE_ALREADY_EXISTS   -2

You try to add an edge that already exists.

#define AT_NO_PATH_FOUND   -3

The query did not yield a path.

#define AT_NO_SUCH_VERTEX   -4

The vertex ID does not exist.

#define AT_NO_SUCH_EDGE   -5

The edge does not exist.

#define AT_GRAPH_DIRECTED   -6

The operation you try to perform is only valid on undirected graphs.

#define AT_NEED_RECALCULATION   -7

You changed the graph and need to recalculate the shortest paths before querying.

Typedef Documentation

typedef float AT_scalar

Use floats or doubles in Atlas?

typedef AT_scalar(* AT_CalculateDistanceCallbackType)(int vID0, int vID1, void *userDef)

Callback function type for distance calculation.
