Interface Dispatcher

All Known Implementing Classes:

SwingDispatcher

public interface Dispatcher

Resolves the platform's UI thread, for running ProgressWorker handlers and for determining whether a model refresh should run asynchronously.

The implementation is provided via ServiceLoader, defaulting to SYNCHRONOUS same-thread dispatch when no implementation is available.

Field Details

SYNCHRONOUS

static final Dispatcher SYNCHRONOUS

A synchronous Dispatcher, running tasks on the calling thread and reporting no UI thread.

Used when no implementation is available, and useful for testing.

Method Details

executor

Executor executor()

Returns an Executor running tasks on the UI thread, resolved for the current context.

Called when a ProgressWorker is executed, on the UI thread, so that context sensitive implementations, such as web frameworks providing a per-session UI thread, can bind to the current context.

Returns:

an Executor running tasks on the UI thread

isUserInterfaceThread

boolean isUserInterfaceThread()

Returns:

true if the calling thread is the UI thread

instance

static Dispatcher instance()

Returns the Dispatcher implementation, as provided via ServiceLoader, or SYNCHRONOUS in case no implementation is available.

Returns:

the Dispatcher implementation to use
