Example 57 with Event

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

the class EventPlayingEntity method play.

/**

 * <p>Please note that the entity version is set according to the version of the event context.
 * Therefore, if the passed event(s) are in fact so called "integration" events and originated
 * from another application, they should be properly imported first.
 * Otherwise, the version conflict is possible.

 * <p>Execution of this method requires the {@linkplain #isTransactionInProgress()
 * presence of active transaction}.

 * @param events the events to play
