# MathFunction

## Object Hierarchy:

## Description:

public interface MathFunction : Object, MathExpression

A Function as part of a MathExpression

All known implementing classes:

- Function

Namespace: GCalc
Package: GCalc-2

## Content:

### Properties:

- public abstract bool closed { get; set; }
  A condition used while parsing, as a flag when the function has been closed or finished and no more parameters should be parsed.
- public abstract uint n_params { get; set construct; }
  Number of parameters required by this function
- public abstract string name { get; set construct; }
  Function's name
- public abstract ExpressionContainer param_types { get; }
  Parameters used by the function, objects representing the expected types. See verify_params

### Methods:

- public abstract MathExpression evaluate () throws Error
  Evaluate the function returning a resulting MathExpression.
- public virtual bool verify_params () throws Error
  Check the paratemeters given to the function agains param_types and number of parameters using n_params
