Description

Author

Rodrigo Faustino

This package can show how to control product stocks with the design observer pattern.

It provides several interface definitions with functions that register observer objects and call those objects when an event occurs.

The email observer interface sends an email message when a product quantity is low in stock.

The stock control request observer interface adds a product to the list of purchases when the stock control is updated.

The stock control subject class uses the observer interfaces to notify when all observer classes run out of stock.
