Constructor Detail

PathGraph

public PathGraph(org.apache.flink.api.java.ExecutionEnvironment env,
                 long vertexCount)

An undirected Graph with n vertices where each vertex v_i connects to adjacent vertices v_i+1 when i < n-1 and v_i-1 when i > 0.

A PathGraph is distinguished from a CycleGraph in that the first and last vertex are not connected, breaking the cycle.

Parameters:

env - the Flink execution environment

vertexCount - number of vertices

Method Detail

generate

public Graph<org.apache.flink.types.LongValue,org.apache.flink.types.NullValue,org.apache.flink.types.NullValue> generate()

Description copied from interface: GraphGenerator

Generates the configured graph.

Returns:

generated graph
