Method Detail

getVertex

Optional<V> getVertex(ExecutionVertexID executionVertexId)

Looks up the SchedulingExecutionVertex for the given ExecutionVertexID.

Parameters:

executionVertexId - identifying the respective scheduling vertex

Returns:

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

getVertexOrThrow

default V getVertexOrThrow(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

Optional<R> getResultPartition(IntermediateResultPartitionID intermediateResultPartitionId)

Looks up the SchedulingResultPartition for the given IntermediateResultPartitionID.

Parameters:

intermediateResultPartitionId - identifying the respective scheduling result partition

Returns:

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

getResultPartitionOrThrow

default R getResultPartitionOrThrow(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
