public boolean isSharable()
```
    Description copied from interface: ChannelHandler
    
    Returns true if this handler is sharable and thus can be added to more than one ChannelPipeline. By default, this method returns false. If this method returns false, you have to create a new handler instance every time you add it to a pipeline because it has unshared state such as member variables.
  - accept
```
protected boolean accept(ChannelHandlerContext ctx,
                         InetSocketAddress remoteAddress)
```
    Description copied from class: AbstractRemoteAddressFilter
    
    This method is called immediately after a Channel gets registered.
    
    Specified by:
    
    accept in class AbstractRemoteAddressFilter<InetSocketAddress>
    
    Returns:
    
    Return true if connections from this IP address and port should be accepted. False otherwise.
