Detailed Description

A function argument.

Member Function Documentation

virtual Argument* FunctionArgument::copy ( ) const

virtual

Returns a copy of the argument definition.

Returns

A copy.

Reimplemented from Argument.

virtual string FunctionArgument::print ( ) const

virtual

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

Returns

Short description.

Reimplemented from Argument.

virtual string FunctionArgument::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.

virtual bool FunctionArgument::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

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.

virtual int FunctionArgument::type ( ) const

virtual

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

Returns

ArgumentType.

Reimplemented from Argument.
