| Method Summary | |
| Message | send(Message query)
Sends a message and waits for a response.
Parameters:
query - The query to send. | | Object | sendAsync(Message query, ResolverListener listener)
Asynchronously sends a message registering a listener to receive a callback
on success or exception. | | void | setEDNS(int level)
Sets the EDNS version used on outgoing messages.
Parameters:
level - The EDNS level to use. | | void | setEDNS(int level, int payloadSize, int flags, List options)
Sets the EDNS information on outgoing messages.
Parameters:
level - The EDNS level to use. | | void | setIgnoreTruncation(boolean flag)
Sets whether truncated responses will be ignored. | | void | setPort(int port)
| | void | setTCP(boolean flag)
| | void | setTSIGKey(TSIG key)
| | void | setTimeout(int secs, int msecs)
Sets the amount of time to wait for a response before giving up. | | void | setTimeout(int secs)
Sets the amount of time to wait for a response before giving up. |
| send | | Message send(Message query) throws IOException(Code) | | Sends a message and waits for a response.
Parameters:
query - The query to send. The response
throws:
IOException - An error occurred while sending or receiving. |
| sendAsync | | Object sendAsync(Message query, ResolverListener listener)(Code) | | Asynchronously sends a message 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 |
| setEDNS | | void setEDNS(int level)(Code) | | Sets the EDNS version used on outgoing messages.
Parameters:
level - The EDNS level to use. 0 indicates EDNS0 and -1 indicates noEDNS.
throws:
IllegalArgumentException - An invalid level was indicated. |
| setEDNS | | void setEDNS(int level, int payloadSize, int flags, List options)(Code) | | Sets the EDNS information on outgoing messages.
Parameters:
level - The EDNS level to use. 0 indicates EDNS0 and -1 indicates noEDNS.
Parameters:
payloadSize - The maximum DNS packet size that this host is capableof receiving over UDP. If 0 is specified, the default (1280) is used.
Parameters:
flags - EDNS extended flags to be set in the OPT record.
Parameters:
options - EDNS options to be set in the OPT record, specified as aList of OPTRecord.Option elements.
throws:
IllegalArgumentException - An invalid field was specified.

| setIgnoreTruncation | | void setIgnoreTruncation(boolean flag)(Code) | | Sets whether truncated responses will be ignored. If not, a truncated
response over UDP will cause a retransmission over TCP.
Parameters:
flag - Indicates whether truncated responses should be ignored. |
| setPort | | void setPort(int port)(Code) | | Sets the port to communicate with on the server
Parameters:
port - The port to send messages to |
| setTCP | | void setTCP(boolean flag)(Code) | | Sets whether TCP connections will be sent by default
Parameters:
flag - Indicates whether TCP connections are made |
| setTSIGKey | | void setTSIGKey(TSIG key)(Code) | | Specifies the TSIG key that messages will be signed with
Parameters:
key - The key |
| setTimeout | | void setTimeout(int secs, int msecs)(Code) | | Sets the amount of time to wait for a response before giving up.
Parameters:
secs - The number of seconds to wait.
Parameters:
msecs - The number of milliseconds to wait. |
| setTimeout | | void setTimeout(int secs)(Code) | | Sets the amount of time to wait for a response before giving up.
Parameters:
secs - The number of seconds to wait. |
