Example 52 with BoundedContext

use of io.spine.server.BoundedContext in project core-java by SpineEventEngine.

the class ProcessManagerRepository method onRegistered.

/**

 *
 * <p>Registers with the {@code CommandBus} for dispatching commands
 * (via {@linkplain DelegatingCommandDispatcher delegating dispatcher}).
 *
 * <p>Registers with the {@code IntegrationBus} for dispatching external events and rejections.

 *     <li>domestic or external event reactor methods;</li>
 *     <li>domestic or external rejection reactor methods.</li>
 * </ul>

 * <p>Throws an {@code IllegalStateException} otherwise.
