Example 18 with CommandBus

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

the class ProcessManager method newRouterFor.

/**
 * Creates a new {@link CommandRouter}.
 *
 * <p>A {@code CommandRouter} allows to create and post one or more commands
 * in response to a command received by the {@code ProcessManager}.
 *
 * <p>A typical usage looks like this:
 *
 * <pre>
 *     {@literal @}Assign
 *     CommandRouted on(MyCommand message, CommandContext context) {
 *         // Create new command messages here.
 *         return newRouterFor(message, context)
 *                  .add(messageOne)
 *                  .add(messageTwo)
 *                  .routeAll();
 *     }
 * </pre>
 *
 * <p>The routed commands are created on behalf of the actor of the original command.
 * That is, the {@code actor} and {@code zoneOffset} fields of created {@code CommandContext}
 * instances will be the same as in the incoming command.
 *
 * @param  commandMessage the source command message
 * @param  commandContext the context of the source command
 * @return new {@code CommandRouter}
