Example Dictionary copy 002

 

 

Description

This example shows how a Vector may be modified destructively or non-destructively using the the copy and setq function.

 

Details

The original Dictionary.

(define x #{dic|a: "The " b: "Rain " c: "in " d: "Spain "}) Returns: #<Dictionary 123456>

The copied Dictionary using the copy function.

(setq clone (copy x)) Returns: #<Dictionary 234567>

The copied Dictionary using the setq function.

(setq twin x) Returns: #<Dictionary 345678>
(display clone) Returns: #{dic|a: "The " b: "Rain " c: "in " d: "Spain "}

The second element of the original Dictionary is modified.

(setq clone.b "Hail" ) Returns: #<Dictionary 123456>
(display clone) Returns: #{dic|a: "The " b: "Hail " c: "in " d: "Spain "}
(display twin) Returns: #{dic|a: "The " b: "Rain " c: "in " d: "Spain "}

The original Dictionary does not contain the modified value.

(display x) Returns: #{a: "The " b: "Rain " c: "in " d: "Spain "}

Notes and Hints

Using the setq function results in objects having the same object id. But the object that is being assigned the copied object has a different object id than original object. In this example twin and x have the same object id while clone has a different object id.
