Method new()

Initialize a new instance of the class

Usage

Quantity$new(netObject)

Arguments

netObject

A NetObject object with the pointer to the .NET Quantity

Returns

A new Quantity object.

---

Method print()

Print the object to the console

Usage

Quantity$print(...)

Arguments

...

Rest arguments.

---

Method printValue()

Print the name of the quantity and its value

Usage

Quantity$printValue()

---

Method printQuantityValue()

Print the value (in scientific notation with 2 digits when needed) and unit of the quantity

Usage

Quantity$printQuantityValue(caption)

Arguments

caption

Text to prepend to the value

---

Method setValue()

Convert value from unit to the base unit and sets the value in base unit.

Usage

Quantity$setValue(value, unit = NULL)

Arguments

value

Value to set. If unit is null, we assume that the value is in base unit

unit

Optional unit in which the value is given.

---

Method hasUnit()

Returns TRUE if the quantity supports the given unit otherwise FALSE. For the list of supported units, use allUnits

Usage

Quantity$hasUnit(unit)

Arguments

unit

Unit to check

---

Method reset()

Ensures that the quantity uses the value computed by its formula. It is a shortcut for self$isFixedValue <- false.

Usage

Quantity$reset()
