AbstractBootstrap (Netty 4.1.109.Final API文档

java.lang.Object
- io.netty.bootstrap.AbstractBootstrap<B,C>

所有已实现的接口:

java.lang.Cloneable

直接已知子类:

Bootstrap, ServerBootstrap
```
public abstract class AbstractBootstrap<B extends AbstractBootstrap<B,C>,C extends Channel>
extends java.lang.Object
implements java.lang.Cloneable
```
AbstractBootstrap is a helper class that makes it easy to bootstrap a Channel. It support method-chaining to provide an easy way to configure the AbstractBootstrap.
When not used in a ServerBootstrap context, the bind() methods are useful for connectionless transports such as datagram (UDP).

  - group
```
public B group(EventLoopGroup group)
```
    The EventLoopGroup which is used to handle all the events for the to-be-created Channel
  - channel
```
public B channel(java.lang.Class<? extends C> channelClass)
```
    The Class which is used to create Channel instances from. You either use this or channelFactory(io.netty.channel.ChannelFactory) if your Channel implementation has no no-args constructor.
  - channelFactory
```
@Deprecated
public B channelFactory(ChannelFactory<? extends C> channelFactory)
```
    已过时。 Use channelFactory(io.netty.channel.ChannelFactory) instead.
  - channelFactory
```
public B channelFactory(ChannelFactory<? extends C> channelFactory)
```
    ChannelFactory which is used to create Channel instances from when calling bind(). This method is usually only used if channel(Class) is not working for you because of some more complex needs. If your Channel implementation has a no-args constructor, its highly recommend to just use channel(Class) to simplify your code.
  - localAddress
```
public B localAddress(java.net.SocketAddress localAddress)
```
    The SocketAddress which is used to bind the local "end" to.
  - localAddress
```
public B localAddress(int inetPort)
```
    另请参阅:
    
    localAddress(SocketAddress)
  - localAddress

public B localAddress(java.lang.String inetHost,
                      int inetPort)
```

  - option
```
public <T> B option(ChannelOption<T> option,
                    T value)
```
    Allow to specify a ChannelOption which is used for the Channel instances once they got created. Use a value of null to remove a previous set ChannelOption.
  - attr
```
public <T> B attr(AttributeKey<T> key,
                  T value)
```
    Allow to specify an initial attribute of the newly created Channel. If the value is null, the attribute of the specified key is removed.
  - extensionsClassLoader
```
public B extensionsClassLoader(java.lang.ClassLoader classLoader)
```
    Load ChannelInitializerExtensions using the given class loader.
    By default, the extensions will be loaded by the same class loader that loaded this bootstrap class.
    
    参数:
    
    classLoader - The class loader to use for loading ChannelInitializerExtensions.
    
    返回:
    
    This bootstrap.
  - validate
```
public B validate()
```
    Validate all the parameters. Sub-classes may override this, but should call the super method in that case.
  - clone
```
public abstract B clone()
```
    Returns a deep clone of this bootstrap which has the identical configuration. This method is useful when making multiple Channels with similar settings. Please note that this method does not clone the EventLoopGroup deeply but shallowly, making the group a shared resource.

public ChannelFuture register()
```
    Create a new Channel and register it with an EventLoop.

    Create a new Channel and bind it.
  - bind
```
public ChannelFuture bind(java.net.InetAddress inetHost,
                          int inetPort)
```

    Returns the configured EventLoopGroup or null if non is configured yet.
  - config
```
public abstract AbstractBootstrapConfig<B,C> config()

    Returns the AbstractBootstrapConfig object that can be used to obtain the current config of the bootstrap.
