| Method Summary | |
| public static InetAddress | getIPByName_OS(String hostname)
Tries to determine IP address by hostname using
Inet4Address.getByName(String) method. | | public static int | sendReceiveTCP(String server, int serverPort, byte[] outBuf, int outBufLen, byte[] inBuf, int inBufLen, int timeout)
Establishes TCP connection, transmit bytes from inBuf,
stores received answer in outBuf. | | public static int | sendReceiveUDP(String server, int serverPort, byte[] outBuf, int outBufLen, byte[] inBuf, int inBufLen, int timeout)
Sends the packet contained in outBuf, receives the answer
and stores it in inBuf array. |
| sendReceiveTCP | | public static int sendReceiveTCP(String server, int serverPort, byte[] outBuf, int outBufLen, byte[] inBuf, int inBufLen, int timeout) throws DomainProtocolException, SocketTimeoutException, SecurityException(Code) | | Establishes TCP connection, transmit bytes from inBuf,
stores received answer in outBuf.
Parameters:
server - the server's IP-address in string form
Parameters:
serverPort - server port
Parameters:
outBuf - bytes of the message to send
Parameters:
outBufLen - length of the outBuf
Parameters:
inBuf - buffer to store received bytes at
Parameters:
inBufLen - length of the inBuf
Parameters:
timeout - time to wait for an answer, in milliseconds; 0 stands forinfinite timeout number of received bytes
throws:
SocketTimeoutException - in case of timeout
throws:
SecurityException - if security violation error occured; normally this happens ifthe access to the network subsystem has not been granted
throws:
DomainProtocolException - if some configuration or network problem encountered TODOpool of connections may speed up things |
