new

Arguments

Returns

A new instance of the class.

Description

The new function creates a new instance of the specified class and initializes any instance variables which have default values associated with them, or assigns them to nil if there is no default specified.

An instance is represented by an open brace, followed by the class name, followed by a sequence of dotted pairs (dotted lists of two elements), each containing an instance variable name and a value, followed by a closing brace. Note that (x . nil) is the same as (x). For example, an object of the class PhPoint would be {PhPoint (x . 5) (y . 0)}.

An instance can be destroyed by destroy.

Example

Gamma> class RegPolygon{sides; length;}
(defclass RegPolygon nil [][length sides])
Gamma> class Square RegPolygon {sides = 4;}
(defclass Square RegPolygon [][length (sides . 4)])
Gamma> polyA = new(RegPolygon);
{RegPolygon (length) (sides)}
Gamma> sqC = new(Square);
{Square (length) (sides . 4)}
Gamma>
