Class 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");
