This class represents Access to a network via sockets.
A SocketPermission consists of a
host specification and a set of "actions" specifying ways to
connect to that host. The host is specified as
该类表示通过套接字对网络的访问。一个SocketPermission由一个主机详细说明和连接这个主机的具体方式的一系列“动作”组成。
主机具体如下
<pre>
host = (hostname | IPv4address | iPv6reference) [:portrange]
portrange = portnumber | -portnumber | portnumber-[portnumber]
</pre>
The host is expressed as a DNS name, as a numerical IP address,
or as "localhost" (for the local machine).
The wildcard "*" may be included once in a DNS name host
specification. If it is included, it must be in the leftmost
position, as in "*.sun.com".
朱基被表示为一个DNS名称，一个数字的IP地址，或“localhost”（表示本地主机）。在DNS名称说明中可以包括
通配符“*”。如果包括，则必须位于最左侧，例如“*.sun.com”。
<p>
The format of the IPv6reference should follow that specified in <a
href="http://www.ietf.org/rfc/rfc2732.txt"><i>RFC&nbsp;2732: Format
for Literal IPv6 Addresses in URLs</i></a>:
IPv6reference格式应遵循RFC2732：Format for Literal IPv6 Addresses in URLs：
<pre>
ipv6reference = "[" IPv6address "]"
</pre>
For example, you can construct a SocketPermission instance
as the following:
例如，你可以按以下方式构造SocketPermission实例：
<pre>
String hostAddress = inetaddress.getHostAddress();
if (inetaddress instanceof Inet6Address) {
sp = new SocketPermission("[" hostAddress "]:" port, action);
} else {
sp = new SocketPermission(hostAddress ":" port, action);
}
</pre>
or 或者
<pre>
String host = url.getHost();
sp = new SocketPermission(host ":" port, action);
</pre>
