Example 1 with RejectionReactorMethod

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

the class Aggregate method reactOn.

/**
 * Dispatches the rejection to which the aggregate reacts.
 *
 * <p>Reacting on a rejection may result in emitting event messages. All the
 * {@linkplain Empty empty} messages are filtered out from the result.
 *
 * @param  rejection the envelope with the rejection
 * @return a list of event messages that the aggregate produces in reaction to
 *         the rejection, or an empty list if the aggregate state does not change in
 *         response to this rejection

Example 2 with RejectionReactorMethod

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

the class ProcessManager method dispatchRejection.

/**
 * Dispatches a rejection to the reacting method of the process manager.
 *
 * @param  rejection the envelope with the rejection
 * @return a list of produced events or an empty list if the process manager does not
 *         produce new events because of the passed event
