newBoundedElastic

default Scheduler newBoundedElastic(int threadCap,
                                    int queuedTaskCap,
                                    java.util.concurrent.ThreadFactory threadFactory,
                                    int ttlSeconds)

Scheduler that dynamically creates a bounded number of ExecutorService-based Workers, reusing them once the Workers have been shut down. The underlying (user or daemon) threads can be evicted if idle for more than ttlSeconds.

The maximum number of created thread pools is bounded by the provided cap.

参数:

threadCap - maximum number of underlying threads to create

queuedTaskCap - maximum number of tasks to enqueue when no more threads can be created. Can be Integer.MAX_VALUE for unbounded enqueueing.

threadFactory - a ThreadFactory to use each thread initialization

ttlSeconds - Time-to-live for an idle Scheduler.Worker

返回:

a new Scheduler that dynamically creates workers with an upper bound to the number of backing threads, reuses threads and evict idle ones

newParallel

default Scheduler newParallel(int parallelism,
                              java.util.concurrent.ThreadFactory threadFactory)

Scheduler that hosts a fixed pool of workers and is suited for parallel work.

参数:

parallelism - Number of pooled workers.

threadFactory - a ThreadFactory to use for the fixed initialized number of Thread

返回:

a new Scheduler that hosts a fixed pool of workers and is suited for parallel work

newSingle

default Scheduler newSingle(java.util.concurrent.ThreadFactory threadFactory)

Scheduler that hosts a single worker and is suited for non-blocking work.

参数:

threadFactory - a ThreadFactory to use for the unique resource of the Scheduler

返回:

a new Scheduler that hosts a single worker
