id="Netty4-Usingnonshareableencodersordecoders">Using non shareable encoders or
decoders</h4><p>If your encoders or decoders is not shareable (eg they have the
@Shareable class annotation), then your encoder/decoder must implement the
<code>org.apache.camel.component.netty.ChannelHandlerFactory</code> interface,
and return a new instance in the <code>newChannelHandler</code> method. This is
to ensure the encoder/decoder can safely be used. If this is not the case, then
the Netty component will log a WARN when<br clear="none"> an endpoint is
created.</p><p>The Netty component offers a
<code>org.apache.camel.component.netty.ChannelHandlerFactories</code> factory
class, that has a number of commonly used methods.</p><h3
