Detailed Description

A sensor value stores a sensor reading as a string with unit and data type. The sensor value class can be used in the following way:

sensor_value_t ref_lock_sensor("Reference", my_lock, "unlocked", "locked"); std::cout << ref_lock_sensor.to_pp_string() << std::endl; //prints Reference: locked

sensor_value_t temp_sensor("Temperature", my_temp, "C"); std::cout << temp_sensor.to_pp_string() << std::endl; //prints Temperature: 38.5 C

sensor_value_t() [1/6]

uhd::sensor_value_t::sensor_value_t	(	const std::string &	name,
		bool	value,
		const std::string &	utrue,
		const std::string &	ufalse
	)

Create a sensor value from a boolean.

Parameters

name	the name of the sensor
value	the value true or false
utrue	the unit string when value is true
ufalse	the unit string when value is false

sensor_value_t() [2/6]

uhd::sensor_value_t::sensor_value_t	(	const std::string &	name,
		signed	value,
		const std::string &	unit,
		const std::string &	formatter = "%d"
	)

Create a sensor value from an integer.

Parameters

name	the name of the sensor
value	the signed integer value
unit	the associated unit type
formatter	the formatter string

sensor_value_t() [3/6]

uhd::sensor_value_t::sensor_value_t	(	const std::string &	name,
		double	value,
		const std::string &	unit,
		const std::string &	formatter = "%f"
	)

Create a sensor value from a real number.

Parameters

name	the name of the sensor
value	the real number value
unit	the associated unit type
formatter	the formatter string

sensor_value_t() [4/6]

uhd::sensor_value_t::sensor_value_t	(	const std::string &	name,
		const std::string &	value,
		const std::string &	unit
	)

Create a sensor value from a string.

Parameters

name	the name of the sensor
value	the real number value
unit	the associated unit type

sensor_value_t() [5/6]

uhd::sensor_value_t::sensor_value_t

(

const std::map< std::string, std::string > &

sensor_dict

)

Create a sensor value from a map.

The map must have the following keys: name, type, value, and unit.

type must one of the following strings: BOOLEAN, INTEGER, REALNUM, or STRING (see data_type_t).

sensor_value_t() [6/6]

uhd::sensor_value_t::sensor_value_t

(

const sensor_value_t &

source

)

Create a sensor value from another sensor value.

Parameters

source

the source sensor value to copy

operator=()

sensor_value_t& uhd::sensor_value_t::operator=

(

const sensor_value_t &

value

)

Assignment operator for sensor value.

to_bool()

bool uhd::sensor_value_t::to_bool

(

void

)

const

convert the sensor value to a boolean

to_int()

signed uhd::sensor_value_t::to_int

(

void

)

const

to_pp_string()

std::string uhd::sensor_value_t::to_pp_string

(

void

)

const

Convert this sensor value into a printable string.

to_real()

double uhd::sensor_value_t::to_real

Member Data Documentation

name

std::string uhd::sensor_value_t::name

The name of the sensor value.

type

data_type_t uhd::sensor_value_t::type

The data type of the value.

unit

std::string uhd::sensor_value_t::unit

The sensor value's unit type. For boolean types, this will be the one of the two units depending upon the value of the boolean true or false.

value

std::string uhd::sensor_value_t::value

The sensor value as a string. For integer and real number types, this will be the output of the formatter. For boolean types, the value will be the string literal "true" or "false".
