Method Details

newSingleThreadScheduler

public static ScheduledExecutorService newSingleThreadScheduler(String threadName)

Creates a single-thread ScheduledExecutorService with a named daemon thread.

Parameters:

threadName - name for the backing thread

Returns:

new single-thread scheduled executor

newManagedScheduler

public static ManagedScheduler newManagedScheduler(String threadName)

Creates a single-thread ManagedScheduler with a named daemon thread. The returned scheduler implements AutoCloseable, making it compatible with MagicRuntime.manage() for automatic shutdown on runtime close.

Parameters:

threadName - name for the backing thread

Returns:

new managed single-thread scheduler

newFixedPool

public static ExecutorService newFixedPool(String threadPrefix,
 int poolSize)

Creates a fixed-size thread pool with named daemon threads.

Parameters:

threadPrefix - prefix for thread names (threads are named prefix-1, prefix-2, etc.)

poolSize - number of threads

Returns:

new fixed thread pool

newManagedPool

public static ManagedExecutor newManagedPool(String threadPrefix,
 int poolSize)

Creates a fixed-size ManagedExecutor with named daemon threads. The returned executor implements AutoCloseable, making it compatible with MagicRuntime.manage() for automatic shutdown on runtime close.

Parameters:

threadPrefix - prefix for thread names

poolSize - number of threads

Returns:

new managed fixed thread pool

shared

public static TaskScheduler shared()

Returns the shared scheduler instance.

Returns:

shared scheduler

create

public static TaskScheduler create(String name,
 @Nullable
 @Nullable ShutdownHookRegistrar shutdownRegistrar)

Creates a new scheduler and registers shutdown if possible.

Parameters:

name - name prefix for threads

shutdownRegistrar - optional shutdown registrar

Returns:

newly created scheduler
