## Detailed Description

A boolean argument.

Accepts zero or one.

## Member Function Documentation

## ◆ copy()

virtual Argument * BooleanArgument::copy | ( |  | ) | const
| virtual

Returns a copy of the argument definition.

Returns
  A copy.

Reimplemented from Argument.

References Argument::Argument().

## ◆ print()

virtual std::string BooleanArgument::print | ( |  | ) | const
| virtual

Returns a short description of the argument definition. Ex. "number" for NumberArgument.

Returns
  Short description.

Reimplemented from Argument.

## ◆ subprintlong()

virtual std::string BooleanArgument::subprintlong | ( |  | ) | const
| protected virtual

This function is called from Argument::printlong() and returns description specific the argument definition type. Should be reimplemented by all subclasses. For example IntegerArgument::subprintlong() might return "an integer" and Argument::printlong() might append " that fulfills the condition: even(\x)".

Returns
  Long description.

Reimplemented from Argument.

## ◆ subtest()

virtual bool BooleanArgument::subtest | ( | MathStructure & | value,
|  | const EvaluationOptions & | eo ) const
| protected virtual

This function is called from Argument::test() and performs validation specific to the argument definition type. Should be reimplemented by all subclasses.

Parameters

  value | Value to test.
  eo | Evaluation options to use if the value needs to be evaluated.

Returns
  true if the value is valid for the argument definition.

Reimplemented from Argument.

## ◆ type()

virtual int BooleanArgument::type | ( |  | ) | const
| virtual

Returns the type of the argument, corresponding to which subclass the object belongs to.

Returns
  ArgumentType.

Reimplemented from Argument.
