getAllPipelinedRegions

Iterable<? extends PR> getAllPipelinedRegions()

Returns all pipelined regions in this topology.

返回:

Iterable over pipelined regions in this topology

getPipelinedRegionOfVertex

default PR getPipelinedRegionOfVertex(VID vertexId)

The pipelined region for a specified vertex.

参数:

vertexId - the vertex id identifying the vertex for which the pipelined region should be returned

返回:

the pipelined region of the vertex

抛出:

IllegalArgumentException - if there is no vertex in this topology with the specified vertex id
