question: public static String toDebugString ( final long socketIdentifier ) { final int ipBits = ( int ) socketIdentifier ; final int port = extractPortNumber ( socketIdentifier ) ; final int inode = ( int ) ( socketIdentifier > > 48 ) ; return Integer . toHexString ( ipBits ) + ":" + port + "/" + inode ; }
target:  Generates a vaguely human-readable format for a given socket identifier.
