public OncRpcTcpClient(InetAddress host, int program, int version) throws OncRpcException, IOException
OncRpcTcpClient
object, which connects
to the ONC/RPC server at host
for calling remote procedures
of the given { program, version }.
Note that the construction of an OncRpcTcpClient
object will result in communication with the portmap process at
host
.

If 0

for the port number.bufferSize
- Size of receive and send buffers. In contrast to
UDP-based ONC/RPC clients, messages larger than the specified
buffer size can still be sent and received. The buffer is only
necessary to handle the messages and the underlaying streams will
break up long messages automatically into suitable pieces.
Specifying zero will select the default buffer size (currently
8192 bytes).OncRpcException

- Maximum timeout in milliseconds when connecting to

timeout setting will apply. Note that this timeout only applies
to the connection phase, but not to later communication.OncRpcException

Please note that while this method supports call batching by
setting the communication timeout to zero
(setTimeout(0)
) you should better use
batchCall(int, org.acplt.oncrpc.XdrAble, boolean)
as it provides better control over when the
batch should be flushed to the server.

Note that batched calls must not expect replies, with the only exception being the last call in a batch:
