ServiceManager.Publish 方法
定义
发布给定的服务类型,但不声明实例。Publishes the given service type, but does not declare an instance. 在请求服务时,将调用 Publish 服务回调来创建实例。When the service is requested, the Publish service callback will be invoked to create the instance. 只会调用该回调一次。The callback is invoked only once. 之后,会将它返回的实例放入缓存。After that, the instance it returned is cached.
重载
| Publish(Type, Object) |
发布给定的服务。Publishes the given service. 服务发布之后,服务实例将保留在服务管理器中,直至释放编辑上下文为止。After it is published, the service instance remains in the service manager until the editing context is disposed of. |
| Publish(Type, PublishServiceCallback) |
发布指定的服务类型,但不声明实例。Publishes the specified service type, but does not declare an instance. 在请求服务时,将调用 Publish 服务回调来创建实例。When the service is requested, the Publish service callback will be invoked to create the instance. 只会调用该回调一次。The callback is invoked only once. 之后,会将它返回的实例放入缓存。After that, the instance it returned is cached. |
| Publish<TServiceType>(PublishServiceCallback<TServiceType>) |
发布给定的服务类型,但尚未声明实例。Publishes the given service type, but does not declare an instance yet. 当该服务被要求时,将调用 |
| Publish<TServiceType>(TServiceType) |
发布给定的服务。Publishes the given service. 服务发布之后,服务实例将保留在服务管理器中,直至释放编辑上下文为止。After it is published, the service instance remains in the service manager until the editing context is disposed of. |
