Returns:

topologically sorted iterable over all vertices

getVertex

public org.apache.flink.runtime.scheduler.adapter.DefaultExecutionVertex getVertex(ExecutionVertexID executionVertexId)

Description copied from interface: SchedulingTopology

Looks up the SchedulingExecutionVertex for the given ExecutionVertexID.

Specified by:

getVertex in interface SchedulingTopology
