Typedef Documentation

typedef enum TAttrType_ TAttrType

Types for tables, sparse and dense attributes.

typedef enum TGraphFlag_ TGraphFlag

Graph Flags, used for quick testing of graph types.

This is very useful for testing graph properties at compile time for partial template specialization as well as compile time assert (CAssert).

Enumeration Type Documentation

enum TAttrType_

Types for tables, sparse and dense attributes.

Enumerator
atInt
atFlt
atStr

Definition at line 23 of file gbase.h.

{atInt, atFlt, atStr} TAttrType;

enum TGraphFlag_

Graph Flags, used for quick testing of graph types.

This is very useful for testing graph properties at compile time for partial template specialization as well as compile time assert (CAssert).

Enumerator
gfUndef	default value, no flags
gfDirected	directed graph (TNGraph, TNEGraph), else graph is undirected TUNGraph
gfMultiGraph	have explicit edges (multigraph): TNEGraph, TNodeEdgeNet
gfNodeDat	network with data on nodes
gfEdgeDat	network with data on edges
gfSources	nodes only store out-edges (but not in-edges). See TBigNet
gfBipart	bipartite graph
gfMx	sentinel, last value for iteration
