| WhoisClient | | final public class WhoisClient extends FingerClient (Code) | | The WhoisClient class implements the client side of the Internet Whois
Protocol defined in RFC 954. To query a host you create a
WhoisClient instance, connect to the host, query the host, and finally
disconnect from the host. If the whois service you want to query is on
a non-standard port, connect to the host at that port.
Here's a sample use:
WhoisClient whois;
whois = new WhoisClient();
try {
whois.connect(WhoisClient.DEFAULT_HOST);
System.out.println(whois.query("foobar"));
whois.disconnect();
} catch(IOException e) {
System.err.println("Error I/O exception: " + e.getMessage());
return;
}

| Constructor Summary | |
| public | WhoisClient()
The default whois constructor. |
| Method Summary | |
| public InputStream | getInputStream(String handle)
Queries the connected whois server for information regarding
the given handle and returns the InputStream of the network connection.
It is up to the programmer to be familiar with the handle syntax
of the whois server. | | public String | query(String handle)
Queries the connected whois server for information regarding
the given handle. |
| DEFAULT_HOST | | final public static String DEFAULT_HOST(Code) | | The default whois host to query. It is set to whois.internic.net.
|
| DEFAULT_PORT | | final public static int DEFAULT_PORT(Code) | | The default whois port. It is set to 43 according to RFC 954.
|
| WhoisClient | | public WhoisClient()(Code) | | The default whois constructor. Initializes the
default port to DEFAULT_PORT .
|
| getInputStream | | public InputStream getInputStream(String handle) throws IOException(Code) | | Queries the connected whois server for information regarding
the given handle and returns the InputStream of the network connection.
It is up to the programmer to be familiar with the handle syntax
of the whois server. You must first connect to a finger server before
calling this method, and you should disconnect after finishing reading
the stream.
Parameters:
handle - The handle to lookup. The InputStream of the network connection of the whois query.Can be read to obtain whois results.
exception:
IOException - If an I/O error occurs during the operation. |
| query | | public String query(String handle) throws IOException(Code) | | Queries the connected whois server for information regarding
the given handle. It is up to the programmer to be familiar with the
handle syntax of the whois server. You must first connect to a whois
server before calling this method, and you should disconnect afterward.
Parameters:
handle - The handle to lookup. The result of the whois query.
exception:
IOException - If an I/O error occurs during the operation. |
