Interface GraphGenerator<K,VV,EV>

Type Parameters:

K - the key type for edge and vertex identifiers

VV - the value type for vertices

EV - the value type for edges

All Known Implementing Classes:

AbstractGraphGenerator, CirculantGraph, CompleteGraph, CycleGraph, EchoGraph, EmptyGraph, GridGraph, HypercubeGraph, PathGraph, RMatGraph, SingletonEdgeGraph, StarGraph

public interface GraphGenerator<K,VV,EV>

Graph generators shall be - parallelizable, in order to create large datasets - scale-free, generating the same graph regardless of parallelism - thrifty, using as few operators as possible Graph generators should prefer to emit edges sorted by the source label.
