Example Pair isIdentical 017

 

 

Description

The isIdentical function compares the object ID of the Pair arguments. In this example the copy and setq functions are used to illustrate how the isIdentical function behaves.

 

Details

The first Pair.

(setq A '( 1 2 3) ) Returns: #<Pair 123456>

The second Pair.

(setq B ' ( 1 2 3) ) Returns: #<Pair 234567>

The copied Pair has a different Object ID.

(setq C (copy A)) Returns: #<Pair 345678>

Pair D has the same Object Id as Pair A.

(setq D A) Returns: #<Pair 123456>

A and B do not have identical Object IDs.

(isIdentical A B) Returns: false

B and C do not have identical Object IDs.

(isIdentical B C) Returns: false

D and A have identical Object IDs.

(isIdentical D A) Returns: true
