Constructor & Destructor Documentation

ola::plugin::usbdmx::JaRuleWidget::JaRuleWidget	(	ola::io::SelectServerInterface *	ss,
		AsyncronousLibUsbAdaptor *	adaptor,
		libusb_device *	device,
		const ola::rdm::UID &	controller_uid
	)

Create a new Ja Rule widget.

Parameters

ss	The SelectServer to run the RDM callbacks on.
adaptor	The LibUsbAdaptor to use.
device	the libusb_device for the Ja Rule widget.
controller_uid	The UID of the controller. This is used for DUB & Mute / Unmute messages.

TODO(simon): Can we instead read the UID from the hardware device itself?

Member Function Documentation

bool ola::plugin::usbdmx::JaRuleWidget::Init ( )

virtual

Initialize the widget.

Returns

true if this widget was initialized correctly, false otherwise.

Implements ola::plugin::usbdmx::Widget.

void ola::plugin::usbdmx::JaRuleWidget::RunFullDiscovery ( ola::rdm::RDMDiscoveryCallback *  callback )

virtual

Start a full discovery operation.

Parameters

callback

The callback run when discovery completes. This may run immediately in some implementations.

Implements ola::rdm::DiscoverableRDMControllerInterface.

void ola::plugin::usbdmx::JaRuleWidget::RunIncrementalDiscovery ( ola::rdm::RDMDiscoveryCallback *  callback )

virtual

Start an incremental discovery operation.

Parameters

callback

The callback run when discovery completes. This may run immediately in some implementations.

Implements ola::rdm::DiscoverableRDMControllerInterface.

bool ola::plugin::usbdmx::JaRuleWidget::SendDMX ( const DmxBuffer &  buffer )

virtual

Send DMX data from this widget.

Parameters

buffer

The DmxBuffer containing the data to send.

Returns

true if the data was sent, false otherwise.

Implements ola::plugin::usbdmx::Widget.

void ola::plugin::usbdmx::JaRuleWidget::SendRDMRequest ( ola::rdm::RDMRequest *  request, ola::rdm::RDMCallback *  on_complete  )

virtual

Send a RDM command.

Parameters

request	the RDMRequest, ownership is transferred.
on_complete	The callback to run when the request completes.

Implementors much ensure that the callback is always run at some point. In other words, there must be no way that a request can be dropped in such a way that the callback is never run. Doing so will either block all subsequent requests, or leak memory depending on the implementation.

Also the implementor of this class may want to re-write the transaction #, and possibly the UID (changing src UIDs isn't addressed by the RDM spec).

The RDMRequest may be a DISCOVERY_COMMAND, if the implementation does not support DISCOVERY_COMMANDs then the callback should be run with ola::rdm::RDM_PLUGIN_DISCOVERY_NOT_SUPPORTED.

Implements ola::rdm::RDMControllerInterface.
