Interface Command<K,V>

All Known Implementing Classes:

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

Method Summary

Modifier and Type	Method	Description
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.

Method Detail

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.

Parameters:

process - The command context through whole Pipeline

context - The Context to be processed by this Command

future - The result container and async listener

Throws:

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.

Throws:

PipelineException
