Imports

io.netty.buffer.ByteBuf, io.netty.channel.ChannelHandler.Sharable, .ChannelHandlerContext, .ChannelPipeline, io.netty.handler.codec.ByteToMessageDecoder, .DelimiterBasedFrameDecoder, .Delimiters, .MessageToMessageDecoder, io.netty.util.internal.ObjectUtil, java.util.List

Decodes a Base64-encoded ByteBuf or US-ASCII String into a ByteBuf. Please note that this decoder must be used with a proper ByteToMessageDecoder such as DelimiterBasedFrameDecoder if you are using a stream-based transport such as TCP/IP. A typical decoder 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());
