vtkTCPNetworkAccessManager is a concrete implementation of vtkNetworkAccessManager that uses tcp/ip sockets for communication between processes.
It supports urls that use "tcp" as their protocol specifier.

◆ NewConnection()

Creates a new connection given the url.
This call may block until the connection can be established. To keep user-interfaces responsive, one can listen to the vtkCommand::ProgressEvent fired periodically by this class while waiting.
vtkNetworkAccessManager can be waiting for atmost one connection at a time. Calling NewConnection() while another connection is pending will raise an error.
To abort the connection and cancel the waiting, simply call AbortPendingConnection() in the vtkCommand::ProgressEvent callback.
Returns the new connection instance on success, otherwise NULL.
URLs are of the following form: <transport>://<address>
- tcp://<hostname>:<port>
- tcp://localhost:<port>?listen=true& – listen for connection on port.
- tcp://localhost:<port>?listen=true&multiple=true – listen for multiple Examples:
- tcp://medea:12345
- tcp://localhost:12345?listen&handshake=3.8.12 Supported parameters: handshake :- specify a message that is matched with the other side listen :- open a server-socket for a client to connect to multiple :- leave server-socket open for more than 1 client to connect (listen must be set to true) nonblocking:- When listen is true, this will result in the call returning NULL if a client connection is not available immediately. It leaves the server socket open for client to connect. timeout :- When connecting to remote i.e listen==false, specify the time (in seconds) for which this call blocks to retry attempts to connect to the host/port. If absent, default is 60s. 0 or negative implies no retry attempts.
