Detailed Description

A set of accepted arguments.

This is used when several different type of argments shall be accepted by a function.

Member Function Documentation

◆ copy()

virtual Argument* ArgumentSet::copy ( ) const
virtual

Returns a copy of the argument definition.

Returns
A copy.

Reimplemented from Argument.

◆ print()

virtual std::string ArgumentSet::print ( ) const
virtual

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

Returns
Short description.

Reimplemented from Argument.

◆ subprintlong()

virtual std::string ArgumentSet::subprintlong ( ) const
protectedvirtual

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 ArgumentSet::subtest ( MathStructure value,
const EvaluationOptions eo 
) const
protectedvirtual

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

Parameters
valueValue to test.
eoEvaluation 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 ArgumentSet::type ( ) const
virtual

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

Returns
ArgumentType.

Reimplemented from Argument.
