类 Base64Decoder

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

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

io.netty.handler.codec.base64.Base64Decoder

所有已实现的接口:

ChannelHandler, ChannelInboundHandler

@ChannelHandler.Sharable
public class Base64Decoder
extends MessageToMessageDecoder<ByteBuf>

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());

从类复制的说明: MessageToMessageDecoder

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

指定者:

decode 在类中 MessageToMessageDecoder<ByteBuf>

参数:

ctx - the ChannelHandlerContext which this MessageToMessageDecoder belongs to

msg - the message to decode to an other one

out - the List to which decoded messages should be added

抛出:

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