Abstract
The observer pattern is used to manage the process by which one object expresses interest in—and receives notification of—changes in another. The observer pattern allows large and complex groups of objects to cooperate with one another with few dependencies between them and is so widely used that you are likely to have come across it if you have developed an application using a modern UI component framework. Table 22-1 puts the observer pattern in context.
