Member Function Documentation

Argument* DataObjectArgument::copy  )  const [virtual]
 

Returns a copy of the argument definition.

Returns:
A copy.

Reimplemented from Argument.

string DataObjectArgument::print  )  const [virtual]
 

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

Returns:
Short description.

Reimplemented from Argument.

virtual string DataObjectArgument::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 bool DataObjectArgument::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.

int DataObjectArgument::type  )  const [virtual]
 

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

Returns:
ArgumentType.

Reimplemented from Argument.
