DO_NOTING

static final DeviceMessageSenderInterceptor DO_NOTING

方法详细资料

preSend

default reactor.core.publisher.Mono<DeviceMessage> preSend(DeviceOperator device,
                                                           DeviceMessage message)

在消息发送前触发. 执行此方法后将使用返回值DeviceMessage进行发送到设备.

参数:

device - 设备操作接口

message - 消息对象

返回:

新的消息

doSend

default reactor.core.publisher.Flux<DeviceMessage> doSend(DeviceOperator device,
                                                          DeviceMessage source,
                                                          reactor.core.publisher.Flux<DeviceMessage> sender)

执行发送时触发.

参数:

device - 设备操作接口

source - 指令

sender - 消息发送逻辑

返回:

新的发送逻辑

afterSent

default <R extends DeviceMessage> reactor.core.publisher.Flux<R> afterSent(DeviceOperator device,
                                                                           DeviceMessage message,
                                                                           reactor.core.publisher.Flux<R> reply)

在消息发送后触发.这里发送后并不是真正的发送，其实只是构造了整个发送的逻辑流Flux(参数 reply),

类型参数:

R - 回复的消息类型

参数:

device - 设备操作接口

message - 源消息

reply - 回复的消息

返回:

新的回复结果

andThen

default DeviceMessageSenderInterceptor andThen(DeviceMessageSenderInterceptor interceptor)

getOrder

default int getOrder()

排序序号,值小的在前,大的再后.

返回:

序号
