io.netty.handler.codec.base64

类 Base64Encoder

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelOutboundHandlerAdapter

io.netty.handler.codec.MessageToMessageEncoder<ByteBuf>

io.netty.handler.codec.base64.Base64Encoder

所有已实现的接口:

ChannelHandler, ChannelOutboundHandler

@ChannelHandler.Sharable
public class Base64Encoder
extends MessageToMessageEncoder<ByteBuf>

Encodes a ByteBuf into a Base64-encoded ByteBuf. A typical setup for TCP/IP would be:

 ChannelPipeline pipeline = ...;

 // Decoders
 pipeline.addLast("frameDecoder", new DelimiterBasedFrameDecoder(80, Delimiters.nulDelimiter()));
 pipeline.addLast("base64Decoder", new Base64Decoder());

 // Encoder
 pipeline.addLast("base64Encoder", new Base64Encoder());

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<ByteBuf>

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
