ola::client::StreamingClient Class Reference

Detailed Description

Send DMX512 data to olad.

StreamingClient sends DMX512 data to OLAD without waiting for an acknowledgement. It's best suited to simple clients which only ever send DMX512 data.

#include <stdlib.h>
#include <unistd.h>
#include <ola/DmxBuffer.h>
#include <ola/Logging.h>
#include <ola/client/StreamingClient.h>

#include <iostream>

using std::cout;
using std::endl;

int main(int, char *[]) {
  unsigned int universe = 1;  // universe to use for sending data

  // turn on OLA logging
  ola::InitLogging(ola::OLA_LOG_WARN, ola::OLA_LOG_STDERR);

  ola::DmxBuffer buffer;  // A DmxBuffer to hold the data.
  buffer.Blackout();  // Set all channels to 0

  // Create a new client.
  ola::client::StreamingClient ola_client(
      (ola::client::StreamingClient::Options()));

  // Setup the client, this connects to the server
  if (!ola_client.Setup()) {
    std::cerr << "Setup failed" << endl;
    exit(1);
  }

  // Send 100 frames to the server. Increment slot (channel) 0 each time a
  // frame is sent.
  for (unsigned int i = 0; i < 100; i++) {
    buffer.SetChannel(0, i);
    if (!ola_client.SendDmx(universe, buffer)) {
      cout << "Send DMX failed" << endl;
      exit(1);
    }
    usleep(25000);   // sleep for 25ms between frames.
  }
  return 0;
}

Constructor & Destructor Documentation

StreamingClient() [1/2]

ola::client::StreamingClient::StreamingClient ( bool  auto_start = true )

explicit

Create a new StreamingClient.

Parameters

auto_start

if set to true, this will automatically start olad if it's not already running.

Deprecated:

Use the constructor that takes an Options struct instead.

StreamingClient() [2/2]

ola::client::StreamingClient::StreamingClient ( const Options &  options )

explicit

Create a new StreamingClient.

Parameters

options

an Options structure.

~StreamingClient()

ola::client::StreamingClient::~StreamingClient

(

)

Destructor. This closes the connection to the olad server if it's still open.

Member Function Documentation

SendDmx()

bool ola::client::StreamingClient::SendDmx ( unsigned int  universe, const DmxBuffer &  data  )

virtual

Send a DmxBuffer to the olad server.

Parameters

universe	the universe to send on.
data	the DMX512 data.

Returns

true if sent successfully, false if the connection to the server has been closed.

Implements ola::client::StreamingClientInterface.

SendDMX()

bool ola::client::StreamingClient::SendDMX ( unsigned int  universe, const DmxBuffer &  data, const SendArgs &  args  )

virtual

Send DMX data.

Parameters

universe	the universe to send to.
data	the DmxBuffer with the data
args	the SendDMXArgs to use for this call.

Implements ola::client::StreamingClientInterface.

Setup()

bool ola::client::StreamingClient::Setup ( )

virtual

Initialize the client and connect to olad.

Returns

true if the initialization completed successfully, false if there was a failure.

Implements ola::client::StreamingClientInterface.

Stop()

void ola::client::StreamingClient::Stop ( )

virtual

Close the connection to the olad server. This does not need to be called since ~StreamingClient() will close the connection if it's still open when the object is destroyed.

Implements ola::client::StreamingClientInterface.
