ons for a new channel b.setOption("localAddress", new {@link InetSocketAddress}(8080)); b.setOption("tcpNoDelay", true); b.setOption("receiveBufferSize", 1048576); For the detailed list of available options, please refer to {@link ChannelConfig} and its sub-types
Configuring a channel pipeline
Every channel has its own {@link ChannelPipeline} and you can configure itin two ways.
{@linkplain #setPipeline(ChannelPipeline) The first approach} is to usethe default pipeline and let the bootstrap to shallow-copy the default pipeline for each new channel:
```
 ConnectionlessBootstrap b = ...; {@link ChannelPipeline} p = b.getPipeline();// Add handlers to the pipeline. p.addLast("encoder", new EncodingHandler()); p.addLast("decoder", new DecodingHandler()); p.addLast("logic",   new LogicHandler()); 
```
Please note 'shallow-copy' here means that the added {@link ChannelHandler}s are not cloned but only their references are added to the new pipeline. Therefore, you have to choose the second approach if you are going to open more than one {@link Channel} whose {@link ChannelPipeline} contains any{@link ChannelHandler} whose {@link ChannelPipelineCoverage} is {@code "one"}.
{@linkplain #setPipelineFactory(ChannelPipelineFactory) The second approach}is to specify a {@link ChannelPipelineFactory} by yourself and have fullcontrol over how a new pipeline is created. This approach is more complex:
```
 ConnectionlessBootstrap b = ...; b.setPipelineFactory(new MyPipelineFactory()); public class MyPipelineFactory implements  {@link ChannelPipelineFactory} {// Create a new pipeline for a new channel and configure it here ... } 
```
Applying different settings for different {@link Channel}s
{@link ConnectionlessBootstrap} is just a helper class. It neitherallocates nor manages any resources. What manages the resources is the {@link ChannelFactory} implementation you specified in the constructor of{@link ConnectionlessBootstrap}. Therefore, it is OK to create as many {@link ConnectionlessBootstrap} instances as you want to applydifferent settings for different {@link Channel}s.
