Detailed Description

Compute statistics on ROIs in an array.

Constructor & Destructor Documentation

NDPluginROIStat()

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

Constructor for NDPluginROIStat; 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]	maxROIs	The maximum number of ROIs this plugin supports. 1 is minimum.
[in]	maxBuffers	The maximum number of NDArray buffers that the NDArrayPool for this driver is allowed to allocate. Set this to -1 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 -1 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 NDPluginROIStat::processCallbacks ( NDArray *  pArray )

virtual

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

Computes statistics on the ROIs if NDPluginROIStatUse is 1. If NDPluginROIStatNDArrayCallbacks is 1 then it also does NDArray callbacks.

Parameters

[in]

pArray

The NDArray from the callback.

Implements NDPluginDriver.

writeInt32()

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

virtual

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

For other parameters it calls NDPluginDriver::writeInt32 to see if that method understands the parameter. 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	The value to write.

Returns

asynStatus

Reimplemented from NDPluginDriver.
