io.netty.handler.codec.memcache.AbstractMemcacheObjectDecoder

io.netty.handler.codec.memcache.binary.AbstractBinaryMemcacheDecoder<M>

所有已实现的接口:

ChannelHandler, ChannelInboundHandler

直接已知子类:

BinaryMemcacheRequestDecoder, BinaryMemcacheResponseDecoder

@UnstableApi
public abstract class AbstractBinaryMemcacheDecoder<M extends BinaryMemcacheMessage>
extends AbstractMemcacheObjectDecoder

Decoder for both BinaryMemcacheRequest and BinaryMemcacheResponse.

The difference in the protocols (header) is implemented by the subclasses.

构造器详细资料

AbstractBinaryMemcacheDecoder

protected AbstractBinaryMemcacheDecoder()

Create a new AbstractBinaryMemcacheDecoder with default settings.

AbstractBinaryMemcacheDecoder

protected AbstractBinaryMemcacheDecoder(int chunkSize)

Create a new AbstractBinaryMemcacheDecoder with custom settings.

参数:

chunkSize - the maximum chunk size of the payload.

方法详细资料

decode

protected void decode(ChannelHandlerContext ctx,
                      ByteBuf in,
                      java.util.List<java.lang.Object> out)
               throws java.lang.Exception

从类复制的说明: ByteToMessageDecoder

Decode the from one ByteBuf to an other. This method will be called till either the input ByteBuf has nothing to read when return from this method or till nothing was read from the input ByteBuf.

指定者:

decode 在类中 ByteToMessageDecoder

参数:

ctx - the ChannelHandlerContext which this ByteToMessageDecoder belongs to

in - the ByteBuf from which to read data

out - the List to which decoded messages should be added

抛出:

java.lang.Exception - is thrown if an error occurs

channelInactive

public void channelInactive(ChannelHandlerContext ctx)
                     throws java.lang.Exception

When the channel goes inactive, release all frames to prevent data leaks.

指定者:

channelInactive 在接口中 ChannelInboundHandler

覆盖:

channelInactive 在类中 ByteToMessageDecoder

参数:

ctx - handler context

抛出:

java.lang.Exception

resetDecoder

protected void resetDecoder()

Prepare for next decoding iteration.

decodeHeader

protected abstract M decodeHeader(ByteBuf in)

Decode and return the parsed BinaryMemcacheMessage.

参数:

in - the incoming buffer.

返回:

the decoded header.

buildInvalidMessage

protected abstract M buildInvalidMessage()

Helper method to create a upstream message when the incoming parsing did fail.

返回:

a message indicating a decoding failure.
