直接已知子类:

AbstractBinaryMemcacheEncoder

@UnstableApi
public abstract class AbstractMemcacheObjectEncoder<M extends MemcacheMessage>
extends MessageToMessageEncoder<java.lang.Object>

A general purpose AbstractMemcacheObjectEncoder that encodes MemcacheMessages.

Note that this class is designed to be extended, especially because both the binary and ascii protocol require different treatment of their messages. Since the content chunk writing is the same for both, the encoder abstracts this right away.

方法详细资料

encode

protected void encode(ChannelHandlerContext ctx,
                      java.lang.Object msg,
                      java.util.List<java.lang.Object> out)
               throws java.lang.Exception

从类复制的说明: MessageToMessageEncoder

Encode from one message to an other. This method will be called for each written message that can be handled by this encoder.

指定者:

encode 在类中 MessageToMessageEncoder<java.lang.Object>

参数:

ctx - the ChannelHandlerContext which this MessageToMessageEncoder belongs to

msg - the message to encode to an other one

out - the List into which the encoded msg should be added needs to do some kind of aggregation

抛出:

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

acceptOutboundMessage

public boolean acceptOutboundMessage(java.lang.Object msg)
                              throws java.lang.Exception

从类复制的说明: MessageToMessageEncoder

Returns true if the given message should be handled. If false it will be passed to the next ChannelOutboundHandler in the ChannelPipeline.

覆盖:

acceptOutboundMessage 在类中 MessageToMessageEncoder<java.lang.Object>

抛出:

java.lang.Exception

encodeMessage

protected abstract ByteBuf encodeMessage(ChannelHandlerContext ctx,
                                         M msg)

Take the given MemcacheMessage and encode it into a writable ByteBuf.

参数:

ctx - the channel handler context.

msg - the message to encode.

返回:

the ByteBuf representation of the message.
