@class Net::StdTcpClient
|
|
|
|
A TcpClient object is used to communicate with a TcpServer. Any
|
|
number of clients can connect to a TcpServer, each connected
|
|
client spawns a TcpClientConnection object on the server side
|
|
which represents this client on the server. Sending and
|
|
receiving data is handled through streams, streams offer
|
|
the most flexible model to read and write data in different
|
|
formats by connecting different stream readers and stream
|
|
writers. The idea is to write data to the send stream, and
|
|
to send of the accumulated data in the send stream once
|
|
by calling the Send() method. To receive data from the
|
|
server, call the Recv() method which will either block
|
|
until, or return true in non-blocking mode as soon as data
|
|
is available. The received data will be written into the
|
|
receive stream, where the application can read it in any
|
|
way it desires.
