Specified by:

getVertices in interface BaseTopology<ExecutionVertexID,IntermediateResultPartitionID,SchedulingExecutionVertex,SchedulingResultPartition>

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

Parameters:

executionVertexId - identifying the respective scheduling vertex

Returns:

The respective scheduling vertex

getResultPartition

public org.apache.flink.runtime.scheduler.adapter.DefaultResultPartition getResultPartition(IntermediateResultPartitionID intermediateResultPartitionId)

Description copied from interface: SchedulingTopology

Looks up the SchedulingResultPartition for the given IntermediateResultPartitionID.

Specified by:

getResultPartition in interface SchedulingTopology

Parameters:

intermediateResultPartitionId - identifying the respective scheduling result partition

getAllPipelinedRegions in interface Topology<ExecutionVertexID,IntermediateResultPartitionID,SchedulingExecutionVertex,SchedulingResultPartition,SchedulingPipelinedRegion>

Returns:

Iterable over pipelined regions in this topology

getPipelinedRegionOfVertex

public DefaultSchedulingPipelinedRegion getPipelinedRegionOfVertex(ExecutionVertexID vertexId)

Description copied from interface: Topology

The pipelined region for a specified vertex.

Specified by:

getPipelinedRegionOfVertex in interface Topology<ExecutionVertexID,IntermediateResultPartitionID,SchedulingExecutionVertex,SchedulingResultPartition,SchedulingPipelinedRegion>

Parameters:

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

Returns:

the pipelined region of the vertex

getEdgeManager

public EdgeManager getEdgeManager()

notifyExecutionGraphUpdated
