Detailed Description

A definition for integer arguments.

These arguments allows numerical integer values. The value can be restricted to a max and/or min value.


Member Function Documentation

virtual bool IntegerArgument::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.

virtual string IntegerArgument::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.

virtual void IntegerArgument::set ( const Argument arg  )  [virtual]

Sets the argument to a copy of an argument definition.

Parameters:
arg Argument to copy.

Reimplemented from Argument.

virtual Argument* IntegerArgument::copy (  )  const [virtual]

Returns a copy of the argument definition.

Returns:
A copy.

Reimplemented from Argument.

virtual string IntegerArgument::print (  )  const [virtual]

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

Returns:
Short description.

Reimplemented from Argument.

virtual int IntegerArgument::type (  )  const [virtual]

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

Returns:
ArgumentType.

Reimplemented from Argument.
