====== Будьте осторожны с развилками по событиям ======

{{tag>развилка параллельная_развилка развилка_по_событиям}}

Развилка по событиям немедленно прерывает ожидание всех событий при наступлении любого из них.
Если необходимо реализовать более гибкую бизнес-логику, используйте параллельную развилку и событие-останов.

===== Примечания =====

Обратите внимание на разницу между диаграммами: если процесс "[[#как_надо]]" ожидает прихода сообщения постоянно, то процесс "[[#как_не_надо]]" прекращает ожидание, когда срабатывает таймер.
В этой схеме, если сообщение приходит во время выяснения причины задержки, оно не будет обработано и в результате процесс зависнет после возврата к развилке по событиям.
