Examples of org.fireflow.engine.beanfactory.IBeanFactory

org.fireflow.engine.beanfactory.IBeanFactory
Engine把创建bean实例的工作委派给该服务。
Engine在如下情况下需要获得相关Bean的实例(未全部枚举)。
1)Tool类型的Task,Engine通过该服务获得ApplicationHandler的实例然后调用其方法 IApplicationHandler.execute(ITaskInstance taskInstace)
2)Engine在触发事件时，需要获得相关Listener的实例 3)在分配工作项的时候需要获得IAssignmentHandler的实例。 @author 非也,nychen2000@163.com
