Example Directory remove 003

 

 

Description

This example defines a Directory and uses the remove function to non-destructively delete a key-value binding by specifying the Directory key. If the key does not exist in the Directory then the same Directory is returned unchanged.

 

Details

(setq Z #{dir| A: "Now" B: "is" C: "the" D: "Time"} ) Returns: #<Directory 123456>

Removes the key-value binding with key D: and copies the result to a new Directory.

(setq A (remove D: Z)) Returns: #<Directory 234567>

Displays the modified Directory.

(display A) Returns: #{dir| A: "Now" B: "is" C: "the" }

The original Directory still remains unchanged.

(display Z) Returns: #{A: "Now" B: "is" C: "the" D: "Time"}

The key F: is not found in Directory Z.

(setq A (remove F: Z)) Returns: #<Directory 345678>

If the key is not found, the original Directory remains unchanged.

(display Z) Returns: #{A: "Now" B: "is" C: "the" D: "Time"}
