Event Command Map

Overview

An Event Command Map executes commands in response to events on a given Event Dispatcher.

Basic Usage

eventCommandMap
    .map(SignOutEvent.SIGN_OUT, SignOutEvent)
    .toCommand(SignOutCommand);

eventDispatcher.dispatchEvent(new SignOutEvent(SignOutEvent.SIGN_OUT));

Note: for a less verbose and more performant command mechanism see the MessageCommandMap extension.
