## 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

## Constructor & Destructor Documentation

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

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

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

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

## Member Function Documentation

bool uhd::sensor_value_t::to_bool | ( | void |  | ) | const

convert the sensor value to a boolean

signed uhd::sensor_value_t::to_int | ( | void |  | ) | const

convert the sensor value to an integer

std::string uhd::sensor_value_t::to_pp_string | ( | void |  | ) | const

Convert this sensor value into a printable string.

double uhd::sensor_value_t::to_real | ( | void |  | ) | const

convert the sensor value to real number

## Member Data Documentation

const std::string uhd::sensor_value_t::name

The name of the sensor value.

const data_type_t uhd::sensor_value_t::type

The data type of the value.

const 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.

const 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".
