All Implemented Interfaces:: ChannelHandler

public class Base64Decoder
extends MessageToMessageDecoder<Buffer>

Decodes a Base64-encoded Buffer or US-ASCII String into a Buffer. 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());

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`protected void`	`decode(ChannelHandlerContext ctx, Buffer msg)`	Decode from one message to another.
`boolean`	`isSharable()`	Returns `true` if this handler is sharable and thus can be added to more than one `ChannelPipeline`.

  - isSharable
```
public boolean isSharable()
```
    Description copied from interface: ChannelHandler
    
    Returns true if this handler is sharable and thus can be added to more than one ChannelPipeline. By default, this method returns false. If this method returns false, you have to create a new handler instance every time you add it to a pipeline because it has unshared state such as member variables.
  - decode
```
protected void decode(ChannelHandlerContext ctx,
                      Buffer msg)
               throws Exception
```
    Description copied from class: MessageToMessageDecoder
    
    Decode from one message to another. This method will be called for each written message that can be handled by this decoder.
    The message will be disposed of after this call.
    Subclasses that wish to sometimes pass messages through, should instead override the MessageToMessageDecoder.decodeAndClose(ChannelHandlerContext, Object) method.
    
    Overrides:
    
    decode in class MessageToMessageDecoder<Buffer>
    
    Parameters:
    
    ctx - the ChannelHandlerContext which this MessageToMessageDecoder belongs to
    
    msg - the message to decode to another one
    
    Throws:
    
    Exception - is thrown if an error occurs
