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.
