Constructor & Destructor Documentation

◆ NDPluginCodec()

NDPluginCodec::NDPluginCodec	(	const char *	portName,
		int	queueSize,
		int	blockingCallbacks,
		const char *	NDArrayPort,
		int	NDArrayAddr,
		int	maxBuffers,
		size_t	maxMemory,
		int	priority,
		int	stackSize,
		int	maxThreads
	)

Constructor for NDPluginCodec; most parameters are simply passed to NDPluginDriver::NDPluginDriver.

After calling the base class constructor this method sets reasonable default values for all of the ROI parameters.

Parameters

[in]	portName	The name of the asyn port driver to be created.
[in]	queueSize	The number of NDArrays that the input queue for this plugin can hold when NDPluginDriverBlockingCallbacks=0. Larger queues can decrease the number of dropped arrays, at the expense of more NDArray buffers being allocated from the underlying driver's NDArrayPool.
[in]	blockingCallbacks	Initial setting for the NDPluginDriverBlockingCallbacks flag. 0=callbacks are queued and executed by the callback thread; 1 callbacks execute in the thread of the driver doing the callbacks.
[in]	NDArrayPort	Name of asyn port driver for initial source of NDArray callbacks.
[in]	NDArrayAddr	asyn port driver address for initial source of NDArray callbacks.
[in]	maxBuffers	The maximum number of NDArray buffers that the NDArrayPool for this driver is allowed to allocate. Set this to 0 to allow an unlimited number of buffers.
[in]	maxMemory	The maximum amount of memory that the NDArrayPool for this driver is allowed to allocate. Set this to 0 to allow an unlimited amount of memory.
[in]	priority	The thread priority for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags.
[in]	stackSize	The stack size for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags.
[in]	maxThreads	The maximum number of threads this driver is allowed to use. If 0 then 1 will be used.

Member Function Documentation

◆ processCallbacks()

void NDPluginCodec::processCallbacks ( NDArray * pArray )

virtual

Callback function that is called by the NDArray driver with new NDArray data.

Does JPEG or Blosc compression on the array. If compression is None or fails the input array is passed on without being changed. Does callbacks to all registered clients on the asynGenericPointer interface with the output array.

Parameters

[in] pArray The NDArray from the callback.

Implements NDPluginDriver.

◆ writeInt32()

asynStatus NDPluginCodec::writeInt32	(	asynUser *	pasynUser,
		epicsInt32	value
	)

virtual

Called when asyn clients call pasynInt32->write().

This function performs actions for some parameters, including NDPluginDriverEnableCallbacks and NDPluginDriverArrayAddr. For all parameters it sets the value in the parameter library and calls any registered callbacks..

Parameters

[in]	pasynUser	pasynUser structure that encodes the reason and address.
[in]	value	Value to write.

Reimplemented from NDPluginDriver.
