- - org.jboss.netty.handler.codec.embedder.EncoderEmbedder<E>

All Implemented Interfaces:

CodecEmbedder<E>
```
public class EncoderEmbedder<E>
extends AbstractCodecEmbedder<E>
```
A helper that wraps an encoder so that it can be used without doing actual I/O in unit tests or higher level codecs. For example, you can encode a String into a Base64-encoded ChannelBuffer with Base64Encoder and StringEncoder without setting up the ChannelPipeline and other mock objects by yourself:
```
 String data = "foobar";

 EncoderEmbedder<ChannelBuffer> embedder = new EncoderEmbedder<>(
         new Base64Encoder(), new StringEncoder());

 embedder.offer(data);

 ChannelBuffer encoded = embedder.poll();
 assert encoded.toString(CharsetUtil.US_ASCII).equals("Zm9vYmFy");
 
```
