Class ForkJoinPoolWrapper

java.lang.Object

com.scivicslab.pojoactor.core.ForkJoinPoolWrapper

All Implemented Interfaces:

WorkerPool, AutoCloseable, Executor, ExecutorService

public class ForkJoinPoolWrapper
extends Object
implements WorkerPool

A WorkerPool implementation that wraps ForkJoinPool (work-stealing executor). This is the default implementation that maintains backward compatibility with the original POJO-actor behavior. It uses ForkJoinPool for optimal performance with independent CPU-bound tasks. Note: This implementation does NOT support job cancellation per actor.

Since:

1.0.0

Constructor Details

ForkJoinPoolWrapper

public ForkJoinPoolWrapper()

Creates a ForkJoinPoolWrapper with default parallelism.

ForkJoinPoolWrapper

public ForkJoinPoolWrapper(int parallelism)

Creates a ForkJoinPoolWrapper with specified parallelism.

Parameters:

parallelism - the number of worker threads

Method Details

supportsCancellation

public boolean supportsCancellation()

Description copied from interface: WorkerPool

Returns whether this implementation supports per-actor job cancellation.

Returns false for ForkJoinPool-based implementations. Returns true for ManagedThreadPool.

Specified by:

supportsCancellation in interface WorkerPool

Returns:

true if WorkerPool.cancelJobsForActor(String) actually removes jobs
