Class ExecutionPipeline

java.lang.Object

org.apache.flink.runtime.executiongraph.ExecutionPipeline

public final class ExecutionPipeline
extends Object

An execution pipeline is a scheduling abstraction which defines a set of ExecutionVertex objects which must be deployed together. An ExecutionVertex always belongs to exactly one execution pipeline.

This class is thread-safe.

Method Detail

iterator

public Iterator<ExecutionVertex> iterator()

Returns an Iterator to the vertices which are part of this pipeline.

Returns:

an iterator to the vertices of this pipeline

isFinishing

public boolean isFinishing()

Checks if the pipeline is currently finishing its execution, i.e. all vertices contained in the pipeline have switched to the FINISHING or FINISHED state.

Returns:

true if the pipeline is currently finishing, false otherwise

setAllocatedResource

public void setAllocatedResource(AllocatedResource resource)

Sets the given allocated resource for all vertices included in this pipeline.

Parameters:

resource - the allocated resource to set for all vertices included in this pipeline

updateExecutionState

public void updateExecutionState(ExecutionState executionState)

Updates the execution state for all vertices included in this pipeline.

Parameters:

executionState - the execution state to set for all vertices included in this pipeline
