Detailed Description

URL driver; reads images from URLs, such as Web cameras and Axis video servers, but also files, etc.

Constructor & Destructor Documentation

URLDriver()

URLDriver::URLDriver	(	const char *	portName,
		int	maxBuffers,
		size_t	maxMemory,
		int	priority,
		int	stackSize
	)

Constructor for URLDriver; most parameters are simply passed to ADDriver::ADDriver.

After calling the base class constructor this method creates a thread to read the URL images, and sets reasonable default values for parameters defined in this class, asynNDArrayDriver and ADDriver.

Parameters

[in]	portName	The name of the asyn port driver to be created.
[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.

Member Function Documentation

report()

void URLDriver::report ( FILE *  fp, int  details  )

virtual

Report status of the driver.

Prints details about the driver if details>0. It then calls the ADDriver::report() method.

Parameters

[in]	fp	File pointed passed by caller where the output is written to.
[in]	details	If >0 then driver details are printed.

Reimplemented from asynNDArrayDriver.

URLTask()

void URLDriver::URLTask

(

)

Should be private, but gets called from C, so must be public.

This thread calls computeImage to compute new image data and does the callbacks to send it to higher layers.

It implements the logic for single, multiple or continuous acquisition.

writeInt32()

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

virtual

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

This function performs actions for some parameters, including ADAcquire, ADColorMode, etc. 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 ADDriver.
