// .NAME vtkNetworkAccessManager
// .SECTION Description
// vtkNetworkAccessManager is used to create new connections and monitor
// activity of those connections. This is an abstract class that defines the
// interface. Concrete implementations of this class can be written to support
// tcp/ip socket or ssl or ssh based network connections among processes.

public:
vtkTypeMacro(vtkNetworkAccessManager, vtkObject);
void PrintSelf(ostream& os, vtkIndent indent);
// Description:
// 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 -- listen for connection on port.
// * tcp://localhost:<port>/listenmultiple -- listen for multiple
// Examples:
// * tcp://medea:12345
// * tcp://localhost:12345/listen
// * ssh://utkarsh@medea
// * http://kitware-server/session?id=12322&authorization=12
