接口 DatagramSocketFactory

所有已知实现类:

DefaultDatagramSocketFactory

public interface DatagramSocketFactory

The DatagramSocketFactory interface provides a means for the programmer to control the creation of datagram sockets and provide his own DatagramSocket implementations for use by all classes derived from DatagramSocketClient . This allows you to provide your own DatagramSocket implementations and to perform security checks or browser capability requests before creating a DatagramSocket.
