org.jboss.netty.channel.socket
类 DefaultDatagramChannelConfig

java.lang.Object
  org.jboss.netty.channel.DefaultChannelConfig
      org.jboss.netty.channel.socket.DefaultDatagramChannelConfig

所有已实现的接口：: ChannelConfig, DatagramChannelConfig

public class DefaultDatagramChannelConfig
extends DefaultChannelConfig
implements DatagramChannelConfig
extends DefaultChannelConfig
implements DatagramChannelConfig

DatagramChannelConfig默认实现.

构造方法摘要
`DefaultDatagramChannelConfig(java.net.DatagramSocket socket)` 创建一个实例.

方法摘要
`java.net.InetAddress`	`getInterface()` 获取多播数据包的网络接口地址.
`java.net.NetworkInterface`	`getNetworkInterface()` 获取`DatagramChannel`发送的外发多播数据包的网络接口.
`int`	`getReceiveBufferSize()` 返回 `SO_RCVBUF` 属性.
`ReceiveBufferSizePredictor`	`getReceiveBufferSizePredictor()` 返回预测套接字接收缓冲可读字节的`ReceiveBufferSizePredictor`.默认预测机是 `FixedReceiveBufferSizePredictor(768)`.
`ReceiveBufferSizePredictorFactory`	`getReceiveBufferSizePredictorFactory()` 返回当新channel被创建并且`ReceiveBufferSizePredictor`没有设置时用于创建 `ReceiveBufferSizePredictor`的 `ReceiveBufferSizePredictorFactory`.If no predictor was set for the channel, `DatagramChannelConfig.setReceiveBufferSizePredictor(ReceiveBufferSizePredictor)` will be called with the new predictor.
`int`	`getSendBufferSize()` 返回 `SO_SNDBUF` 属性.
`int`	`getTimeToLive()` 获取发送到`DatagramChannel`的多播数据包的默认生存时间.
`int`	`getTrafficClass()` 返回traffic类.
`boolean`	`isBroadcast()` 返回 `SO_BROADCAST` 属性.
`boolean`	`isLoopbackModeDisabled()` 判断是否为多播数据报设置了本地回路.
`boolean`	`isReuseAddress()` 返回 `SO_REUSEADDR` 属性.
`void`	`setBroadcast(boolean broadcast)` 设置 `SO_BROADCAST` 属性.
`void`	`setInterface(java.net.InetAddress interfaceAddress)` 设置多播数据包使用的网络接口地址.
`void`	`setLoopbackModeDisabled(boolean loopbackModeDisabled)` 设置多播数据报的本地回路.
`void`	`setNetworkInterface(java.net.NetworkInterface networkInterface)` 设置`DatagramChannel`发送的外发多播数据包的网络接口.
`boolean`	`setOption(java.lang.String key, java.lang.Object value)` 使用指定的name和value设置配置属性.要正确重写该方法,你必须调用父类: public boolean setOption(String name, Object value) { if (super.setOption(name, value)) { return true; } if (name.equals("additionalOption")) { ....
`void`	`setReceiveBufferSize(int receiveBufferSize)` 返回 `SO_RCVBUF` 属性.
`void`	`setReceiveBufferSizePredictor(ReceiveBufferSizePredictor predictor)` 设置预测套接字接收缓冲可读字节的`ReceiveBufferSizePredictor`.
`void`	`setReceiveBufferSizePredictorFactory(ReceiveBufferSizePredictorFactory predictorFactory)` Sets the `ReceiveBufferSizePredictor` which creates a new `ReceiveBufferSizePredictor` when a new channel is created and no `ReceiveBufferSizePredictor` was set.
`void`	`setReuseAddress(boolean reuseAddress)` 设置 `SO_REUSEADDR` 属性.
`void`	`setSendBufferSize(int sendBufferSize)` 设置 `SO_SNDBUF` 属性.
`void`	`setTimeToLive(int ttl)` 设置`DatagramChannel`发送出去的多播数据包的默认生存时间,以便控制多播的范围.
`void`	`setTrafficClass(int trafficClass)` 如`DatagramSocket.setTrafficClass(int)`一样设置traffic类.

从类 org.jboss.netty.channel.DefaultChannelConfig 继承的方法
`getBufferFactory, getConnectTimeoutMillis, getPipelineFactory, setBufferFactory, setConnectTimeoutMillis, setOptions, setPipelineFactory`

从类 java.lang.Object 继承的方法
`equals, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait`

从接口 org.jboss.netty.channel.ChannelConfig 继承的方法
`getBufferFactory, getConnectTimeoutMillis, getPipelineFactory, setBufferFactory, setConnectTimeoutMillis, setOptions, setPipelineFactory`

构造方法详细信息

DefaultDatagramChannelConfig

public DefaultDatagramChannelConfig(java.net.DatagramSocket socket)

创建一个实例.

方法详细信息

setOption

public boolean setOption(java.lang.String key,
                         java.lang.Object value)

从接口 ChannelConfig 复制的描述

使用指定的name和value设置配置属性.要正确重写该方法,你必须调用父类:

 public boolean setOption(String name, Object value) {
     if (super.setOption(name, value)) {
         return true;
     }
 
     if (name.equals("additionalOption")) {
         ....
         return true;
     }
 
     return false;
 }

指定者：: 接口 ChannelConfig 中的 setOption
覆盖：: 类 DefaultChannelConfig 中的 setOption

返回：: 只有当属性被设置才返回true
