Class SocketUtils2

java.lang.Object

io.netty.util.internal.SocketUtils2

public final class SocketUtils2
extends Object

Provides socket operations with privileges enabled. This is necessary for applications that use the SecurityManager to restrict SocketPermission to their application. By asserting that these operations are privileged, the operations can proceed even if some code in the calling chain lacks the appropriate SocketPermission.
