Method Detail

getVertices

public Iterable<org.apache.flink.runtime.scheduler.adapter.DefaultExecutionVertex> getVertices()

Description copied from interface: Topology

Returns an iterable over all vertices, topologically sorted.

Specified by:

getVertices in interface Topology<ExecutionVertexID,IntermediateResultPartitionID,org.apache.flink.runtime.scheduler.adapter.DefaultExecutionVertex,org.apache.flink.runtime.scheduler.adapter.DefaultResultPartition>

Returns:

topologically sorted iterable over all vertices

containsCoLocationConstraints

public boolean containsCoLocationConstraints()

Description copied from interface: Topology

Returns whether the topology contains co-location constraints. Co-location constraints are currently used for iterations.

Specified by:

containsCoLocationConstraints in interface Topology<ExecutionVertexID,IntermediateResultPartitionID,org.apache.flink.runtime.scheduler.adapter.DefaultExecutionVertex,org.apache.flink.runtime.scheduler.adapter.DefaultResultPartition>

Returns:

whether the topology contains co-location constraints

getVertex

public Optional<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<org.apache.flink.runtime.scheduler.adapter.DefaultExecutionVertex,org.apache.flink.runtime.scheduler.adapter.DefaultResultPartition>

Parameters:

executionVertexId - identifying the respective scheduling vertex

Returns:

Optional containing the respective scheduling vertex or none if the vertex does not exist

getResultPartition

public Optional<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<org.apache.flink.runtime.scheduler.adapter.DefaultExecutionVertex,org.apache.flink.runtime.scheduler.adapter.DefaultResultPartition>

Parameters:

intermediateResultPartitionId - identifying the respective scheduling result partition

Returns:

Optional containing the respective scheduling result partition or none if the partition does not exist
