public interface PipelinedRegion<VID extends VertexID,RID extends ResultID,V extends Vertex<VID,RID,V,R>,R extends Result<VID,RID,V,R>>

A pipelined region is a set of vertices connected via pipelined data exchanges.

方法概要

限定符和类型	方法和说明
boolean	contains(VID vertexId) Returns whether the vertex is in this pipelined region or not.
V	getVertex(VID vertexId) Returns the vertex with the specified vertex id.
Iterable<? extends V>	getVertices() Returns vertices that are in this pipelined region.

方法详细资料

getVertices

Iterable<? extends V> getVertices()

Returns vertices that are in this pipelined region.

返回:

Iterable over all vertices in this pipelined region

getVertex

V getVertex(VID vertexId)

Returns the vertex with the specified vertex id.

参数:

vertexId - the vertex id used to look up the vertex

返回:

the vertex with the specified id

抛出:

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

contains

boolean contains(VID vertexId)

Returns whether the vertex is in this pipelined region or not.

参数:

vertexId - the vertex id used to look up

返回:

the vertex is in this pipelined region or not
