Detailed Description

Sensor support for a simple pulse counter device.

This implementation supports a device that can configured with a reporting period value ( e.g. 1 sec, or 1/10 sec). Samples from the device are little-endian 4 byte unsigned integer counts at the reporting period. This class currently has hard-coded ioctl commands to the dmd_mmat device driver which supports a counter on a Diamond DMMAT card.

Member Function Documentation

void DSMSensor::addCalFile ( CalFile val)
inherited

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)
inherited

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.

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

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.

bool nidas::core::DSMSensor::allowOpen ( )
inlineinherited
void DSMSensor::applyConversions ( SampleTag stag,
SampleT< float > *  outs,
float *  results = 0 
)
protectedinherited

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. Derived classes can use this method in their process method to correct for inherent, constant, sampling lags of a sensor. A fixed sample lag, in fractional seconds, can be set for a sensor in the XML:

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:

<parameter name="lag" type = "float" value="0.186"/>

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.

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.
