Detailed Description

DSMSensor provides the basic support for reading, processing and distributing samples from a sensor attached to a DSM.

Much of the implementation of a DSMSensor is delegated to an IODevice and a SampleScanner, which are built with virtual methods. DSMSensor can fill in its attributes from an XML DOM element with fromDOMElement(). One attribute of a DSMSensor is the system device name associated with this sensor, e.g. "/dev/xxx0". Once a device name has been set, then a user of this sensor can call open(), and then ioctl(), read() and write(), which are carried out by the IODevice.

SampleClient's can call addRawSampleClient()/removeRawSampleClient() if they want to receive raw Samples from this sensor during real-time operations.

SampleClient's can also call addSampleClient()/removeSampleClient() if they want to receive processed Samples from this sensor.

A common usage of a DSMSensor is to add it to a SensorHandler object with SensorHandler::addSensorPort(). When the SensorHandler::run method has determined that there is data available on a DSMSensor's file descriptor, it will then call the readSamples() method which reads the samples from the IODevice, and forwards the raw and processed samples to all associated SampleClient's of this DSMSensor.

void DSMSensor::addCalFile ( CalFile * val )

Add a calibration file for this DSMSensor.

After this method is finished, DSMSensor will own the pointer, and will delete it in the DSMSensor destructor.

void DSMSensor::addParameter ( Parameter * val )

Add a parameter to this DSMSensor.

DSMSensor will then own the pointer and will delete it in its destructor. If a Parameter exists with the same name, it will be replaced with the new Parameter.

Add a SampleClient to this SampleSource.

The pointer to the SampleClient must remain valid, until after it is removed.

Implements nidas::core::SampleSource.

Referenced by nidas::core::SamplePipeline::addSampleClientForTag().

void DSMSensor::addSampleTag	(	SampleTag *	val	)
throw	(	nidas::util::InvalidParameterException
	)

virtual

Add a SampleTag to this sensor.

DSMSensor will own the SampleTag. Throw an exception the DSMSensor cannot support the sample (bad rate, wrong number of variables, etc). Note that a SampleTag may be changed after it has been added. addSampleTag() is called when a sensor is initialized from the sensor catalog. The SampleTag may be modified later if it is overridden in the actual sensor entry. For this reason, it is wise to wait to scan the SampleTags of a DSMSensor in the validate(), init() or open() methods, which are invoked after fromDOMElement.

void DSMSensor::applyConversions	(	SampleTag *	stag,
		SampleT< float > *	outs,
		float *	results = `0`
	)

protected

Perform variable conversions for the variables in stag whose values and sample time have been set in outs.

This method can be used by subclasses to apply any variable conversions associated with the variables in the given SampleTag, using a general algorithm which loops over each value in each variable. The min/max value limits of a variable are applied also, so if a variable value is converted but lies outside the min/max range, the value is set to floatNAN. Typically this can be the last step applied to the output sample of a sensor's process() method, and note that the sample time must already be set in the output sample outs, since that time will be used to look up conversions in calibration files.

If results is non-null, then the converted values are written into results instead of overwriting the values in outs. This is used when one variable's results may be used to filter other variables without replacing the one variable's results. An example is the Ifan variable in the TRH WisardMote. results must point to enough memory to hold all of the values in outs, including for any Variables with multiple values (getLength() > 1).

Return the sampling lag for this sensor in microseconds.

A positive lag means one should adjust the sample time tags for this sensor earlier in time to achieve a better estimate of the actual time to be associated for each sample.

A fixed sample lag, in fractional seconds, can be set for a sensor in the XML:

void DSMSensor::setHeight ( const std::string & val )

Set sensor height above ground via a string which is added to variable names.

Parameters

val	String containing sensor height and units in meters (m) or centimeters(cm), e.g. "15m". This height string is added to all the variable names, with a "." separator, so that a variable "u" for this sensor becomes "u.15m".

void DSMSensor::setHeight ( float val )

Set sensor height above ground.

Parameters

val	height above ground, in meters. The height is added to all the variable names, with a "." separator, so that a variable "u" for this sensor becomes "u.15m".

void nidas::core::DSMSensor::setId ( dsm_sample_id_t val )

inline

Set the various levels of the sensor identification.

A sensor ID is a 32-bit value comprised of four parts: 6-bit sample type id (not used by DSMSensor), 10-bit DSM id, and 16-bit sensor+sample ids.

void nidas::core::DSMSensor::setIODevice ( IODevice * val )

Set the IODevice for this sensor.

DSMSensor then owns the pointer and will delete it in its destructor.

virtual void nidas::core::DSMSensor::setLagSecs ( double val )

inlineprotectedvirtual

Set the sampling lag for this sensor in seconds.

This lag should then used to correct the timetags of the processed samples in the process() method of derived classes. Note that this lag is not used to alter the timetags of the raw samples. Raw samples are saved with the un-altered timetag that was determined at the moment they were sampled.

The lag is stored as a signed integer of microseconds, so lags should be between += 2147 seconds. No warning or exception is given if the value exceeds that limit. If your lag is greater than that I suggest you junk your sensor! A positive lag means one should adjust the sample time tags for this sensor earlier in time to achieve a better estimate of the actual time to be associated for each sample. A fixed sample lag, in fractional seconds, can be set for a sensor in the XML:

The DSMSensor::fromDOM() method parses this parameter and calls this method to set the lag. process() methods in derived classes must apply this lag value. The DSMSensor base class does not adjust time tags of processed samples.

virtual void nidas::core::DSMSensor::setLatency	(	float	val	)
throw	(	nidas::util::InvalidParameterException
	)

inlinevirtual

Set desired latency, providing some control over the response time vs buffer efficiency tradeoff.

Setting a latency of 1/10 sec means buffer data in the driver for a 1/10 sec, then send the data to user space. Generally it should be set before doing a sensor open().

Parameters

val	Latency, in seconds.

virtual void nidas::core::DSMSensor::setTimeoutMsecs ( int val )

inlinevirtual

Set the sensor timeout value in milliseconds.

A value of 0 means no timeout (e.g. infinite). If no data is received for this period, then the sensor is closed, and re-opened. For efficiency reasons, the system may not actually detect a sensor timeout of less than 1 second, so setting it to less than 1000 milliseconds will likely not reduce the time before a sensor timeout is detected.

bool nidas::core::DSMSensor::_openable

Whether this sensor is allowed to be opened.

Most cases the answer is yes/true. But certain sensors should not be opened due to implementation. e.g. DSMArincSensor when used in conjunction with the UDPArincSensor for then Alta ENET appliance.

The fallout from setting this to false is that the sensor will not be added to SensorHandler.
