Class PipelineRunnable<P>

java.lang.Object

de.aristaflow.adept2.util.threading.PipelineRunnable<P>

Type Parameters:

P - The type of objects that identify a pipeline.

All Implemented Interfaces:

java.lang.Runnable

Deprecated.

Use PipelineRunnable instead.

@Deprecated
public class PipelineRunnable<P>
extends java.lang.Object
implements java.lang.Runnable

A runnable that executes all runnables that are present for a specific object. Think of this runnable as pipeline that executes all work that arrives in the pipeline. As soon as there is no more work, the pipeline (represented by a queue) will be deleted.

Field Detail

pipelineId

protected final P pipelineId

Deprecated.

The identifier of our pipeline.

pipeline

protected final java.util.Queue<java.lang.Runnable> pipeline

Deprecated.

The pipeline providing the work for this runnable.

pipelines

protected final java.util.Map<P,Pair<PipelineRunnable<P>,java.util.Queue<java.lang.Runnable>>> pipelines

Deprecated.

The data structures containing all pipelines from which the current pipeline will be removed as soon as it is empty.

terminate

protected final java.util.concurrent.atomic.AtomicInteger terminate

Deprecated.

A boolean flag to signal this pipeline to terminate. This allows for synchronising across different pipelines.

active

protected volatile boolean active

Deprecated.

A flag to indicate that this pipeline is active.

terminated

protected final java.util.concurrent.CountDownLatch terminated

Deprecated.

The latch allowing others to wait for the termination of this pipeline.

logger

protected final java.util.logging.Logger logger

Deprecated.

The logger which to use for runtime exceptions stemming from executing a runnable. Such an exception will only be logged, the execution of the pipeline will continue.

Constructor Detail

PipelineRunnable

protected PipelineRunnable(P pipelineId,
                           java.util.Queue<java.lang.Runnable> pipeline,
                           java.util.Map<P,Pair<PipelineRunnable<P>,java.util.Queue<java.lang.Runnable>>> pipelines,
                           java.util.concurrent.atomic.AtomicInteger terminate,
                           java.util.logging.Logger logger)

Deprecated.

Creates a new runnable that executes all the work present for a specific object (in a pipeline).

Parameters:

pipelineId - The identifier of our pipeline.

pipeline - The pipeline providing the work for this runnable.

pipelines - The data structures containing all pipelines from which the current pipeline will be removed as soon as it is empty.

terminate - A boolean flag to signal this thread to terminate. This allows for synchronising across different pipelines.

logger - The logger which to use for runtime exceptions stemming from a executing a runnable. Such an exception will only be logged, the execution of the pipeline will continue.

Method Detail

getId

public P getId()

Deprecated.

Gets the ID of this pipeline.

Returns:

The ID of this pipeline.

run

public void run()

Deprecated.

Specified by:

run in interface java.lang.Runnable

awaitTermination

public void awaitTermination()
                      throws java.lang.InterruptedException

Deprecated.

Awaits the termination of this runnable. Either the thread has been interrupted, its termination has been requested or the pipeline is empty.

Throws:

java.lang.InterruptedException - If the waiting thread is interrupted while waiting for this runnable to terminate, an InterruptedException will be thrown.
