RtConnectivity

Namespace: RTPROCESSINGLIB  ·  Library: DSP Library

#include <dsp/rt_connectivity.h>

class RTPROCESSINGLIB::RtConnectivity

Real-time connectivity estimation.

Controller that manages RtConnectivityWorker for online connectivity computation.

src/examples/ex_dsp_rt/main.cpp

RtConnectivity rtConnectivity;
MatrixXd online;
bool connectivityDone = false;
QObject::connect(&rtConnectivity, &RtConnectivity::newConnectivityResultAvailable,
                 [&](const QList<Network>& networks, const ConnectivitySettings&) {
                     online = networks.first().getFullConnectivityMatrix();
                     connectivityDone = true;
                 });
rtConnectivity.append(settings); // computed on the worker thread

Inheritance

Public Methods

RtConnectivity(parent)

Creates the real-time connectivity estimation object.

Parameters:

• parent : *QObject ** Parent QObject (optional).

---

~RtConnectivity()

Destroys the real-time connectivity estimation object.

---

append(connectivitySettings)

Slot to receive incoming data.

Parameters:

• connectivitySettings : const ConnectivitySettings & Data to estimate the connectivity from.

---

restart()

Restarts the thread by interrupting its computation queue, quitting, waiting and then starting it again.

---

stop()

Stops the thread by interrupting its computation queue, quitting and waiting.
