Arguments

Returns

An array of all instance variables defined for the given instance or class. If an instance is queried, then the values of all instance variables for that instance are also reported.

Description

Queries the instance variables of a class or instance.

Example

This example is based on the class and method developed in method, class_add_ivar and class_add_cvar.

    Gamma> polyD;
    {RegPolygon (length) (sides)}
    Gamma> sqB;
    {Square (length) (sides . 4)}
    Gamma> instance_vars(RegPolygon);
    [length sides]
    Gamma> instance_vars(polyD);
    [(length) (sides)]
    Gamma> instance_vars(Square);
    [length (sides . 4)]
    Gamma> instance_vars(sqB);
    [(length) (sides . 4)]
    Gamma>
