Class Base64Encoder

java.lang.Object

io.netty.channel.ChannelOperationHandlerAdapter

io.netty.channel.ChannelOutboundHandlerAdapter

io.netty.channel.ChannelOutboundMessageHandlerAdapter<I>

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

io.netty.handler.codec.base64.Base64Encoder

All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelOperationHandler, io.netty.channel.ChannelOutboundHandler, io.netty.channel.ChannelOutboundMessageHandler<io.netty.buffer.ByteBuf>

@ChannelHandler.Sharable
public class Base64Encoder
extends MessageToMessageEncoder<io.netty.buffer.ByteBuf,io.netty.buffer.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());
