接口 Command<K,V>

所有已知实现类:

LogCommand

public interface Command<K,V>

没有添加netty的@Shareable特性，如果Command被添加如多个pipeline，需要 Command 处理并发等问题

方法概要

限定符和类型	方法和说明
void	exceptionCaught(AbstractPipelineProcess<K,V> process, Context<K,V> context, CompletableFuture<?> future, Throwable cause) Gets called if a Throwable was thrown.
void	onEvent(AbstractPipelineProcess<K,V> process, Context<K,V> context, CompletableFuture<?> future) Execute a unit of processing work to be performed.

方法详细资料

onEvent

void onEvent(AbstractPipelineProcess<K,V> process,
             Context<K,V> context,
             CompletableFuture<?> future)

Execute a unit of processing work to be performed.

A command may either complete the required processing and just return or call async future, or delegate remaining processing to the subsequent command in the enclosing Pipeline by continue fire event.

参数:

process - The command context through whole Pipeline

context - The Context to be processed by this Command

future - The result container and async listener

抛出:

PipelineException - general purpose exception return to indicate abnormal termination

IllegalArgumentException - if context is null

exceptionCaught

void exceptionCaught(AbstractPipelineProcess<K,V> process,
                     Context<K,V> context,
                     CompletableFuture<?> future,
                     Throwable cause)
              throws PipelineException

Gets called if a Throwable was thrown.

抛出:

PipelineException
