/**
* A set of configuration properties of a {@link Channel}.
*
* Please down-cast to more specific configuration type such as
* {@link SocketChannelConfig} or use {@link #setOptions(Map)} to set the
* transport-specific properties:
*
* {@link Channel} ch = ...;
* {@link SocketChannelConfig} cfg = ({@link SocketChannelConfig}) ch.getConfig();
* cfg.setTcpNoDelay(false);
*
*
* Option map
*
* An option map property is a dynamic write-only property which allows
* the configuration of a {@link Channel} without down-casting its associated
* {@link ChannelConfig}. To update an option map, please call {@link #setOptions(Map)}.
*
* All {@link ChannelConfig} has the following options:
*
*
*
* Name Associated setter method
*
* {@code "bufferFactory"} {@link #setBufferFactory(ChannelBufferFactory)}
*
* {@code "connectTimeoutMillis"} {@link #setConnectTimeoutMillis(int)}
*
* {@code "pipelineFactory"} {@link #setPipelineFactory(ChannelPipelineFactory)}
*
*
*
* More options are available in the sub-types of {@link ChannelConfig}. For
* example, you can configure the parameters which are specific to a TCP/IP
* socket as explained in {@link SocketChannelConfig} or {@link NioSocketChannelConfig}.
