Detailed Description

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()

vtkMultiProcessController* vtkTCPNetworkAccessManager::NewConnection ( const char * url )

overridevirtual

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 implies no retry attempts. A negative value implies an infinite number of retries.

Implements vtkNetworkAccessManager.

◆ AbortPendingConnection()

void vtkTCPNetworkAccessManager::AbortPendingConnection ( )

overridevirtual

Used to abort pending connection creation, if any.

Refer to NewConnection() for details.

Implements vtkNetworkAccessManager.

overridevirtual

Process any network activity.

Implements vtkNetworkAccessManager.

◆ GetNetworkEventsAvailable()

bool vtkTCPNetworkAccessManager::GetNetworkEventsAvailable ( )

overridevirtual

Peeks to check if any activity is available.

When this call returns true, ProcessEvents() will always result in some activity processing if called afterword.

Implements vtkNetworkAccessManager.

◆ GetPendingConnectionsPresent()

bool vtkTCPNetworkAccessManager::GetPendingConnectionsPresent ( )

overridevirtual

Returns true is the manager is currently waiting for any connections.
