Method Details

getVertex

SchedulingExecutionVertex getVertex(ExecutionVertexID executionVertexId)

Looks up the SchedulingExecutionVertex for the given ExecutionVertexID.

Parameters:

executionVertexId - identifying the respective scheduling vertex

Returns:

The respective scheduling vertex

Throws:

IllegalArgumentException - If the vertex does not exist

getResultPartition

SchedulingResultPartition getResultPartition(IntermediateResultPartitionID intermediateResultPartitionId)

Looks up the SchedulingResultPartition for the given IntermediateResultPartitionID.

Parameters:

intermediateResultPartitionId - identifying the respective scheduling result partition

Returns:

The respective scheduling result partition

Throws:

IllegalArgumentException - If the partition does not exist

registerSchedulingTopologyListener

void registerSchedulingTopologyListener(SchedulingTopologyListener listener)

Register a scheduling topology listener. The listener will be notified by SchedulingTopologyListener.notifySchedulingTopologyUpdated(SchedulingTopology, List) when the scheduling topology is updated.

Parameters:

listener - the registered listener.
