| DEFAULT_EDNS_PAYLOADSIZE | | final public static int DEFAULT_EDNS_PAYLOADSIZE(Code) | | The default EDNS payload size
|
| DEFAULT_PORT | | final public static int DEFAULT_PORT(Code) | | The default port to send queries to
|
| getTimeout | | long getTimeout()(Code) | | |
| send | | public Message send(Message query) throws IOException(Code) | | Sends a message to a single server and waits for a response. No checking
is done to ensure that the response is associated with the query.
Parameters:
query - The query to send. The response.
throws:
IOException - An error occurred while sending or receiving. |
| sendAsync | | public Object sendAsync(Message query, ResolverListener listener)(Code) | | Asynchronously sends a message to a single server, registering a listener
to receive a callback on success or exception. Multiple asynchronous
lookups can be performed in parallel. Since the callback may be invoked
before the function returns, external synchronization is necessary.
Parameters:
query - The query to send
Parameters:
listener - The object containing the callbacks. An identifier, which is also a parameter in the callback |
| setAddress | | public void setAddress(InetSocketAddress addr)(Code) | | Sets the address of the server to communicate with.
Parameters:
addr - The address of the DNS server |
| setAddress | | public void setAddress(InetAddress addr)(Code) | | Sets the address of the server to communicate with (on the default
DNS port)
Parameters:
addr - The address of the DNS server |
| setDefaultResolver | | public static void setDefaultResolver(String hostname)(Code) | | Sets the default host (initially localhost) to query
|
| setEDNS | | public void setEDNS(int level, int payloadSize, int flags, List options)(Code) | | |
| setEDNS | | public void setEDNS(int level)(Code) | | |
| setIgnoreTruncation | | public void setIgnoreTruncation(boolean flag)(Code) | | |
| setLocalAddress | | public void setLocalAddress(InetSocketAddress addr)(Code) | | Sets the local address to bind to when sending messages.
Parameters:
addr - The local address to send messages from. |
| setLocalAddress | | public void setLocalAddress(InetAddress addr)(Code) | | Sets the local address to bind to when sending messages. A random port
will be used.
Parameters:
addr - The local address to send messages from. |
| setPort | | public void setPort(int port)(Code) | | |
| setTCP | | public void setTCP(boolean flag)(Code) | | |
| setTimeout | | public void setTimeout(int secs, int msecs)(Code) | | |
