The following diagram represents a pattern:
The following diagram represents a pattern:
- which defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and can update automatically.
- which is used to provide a sequential access to elements of a collection without knowing its internal organisation (correct)
- which allows an object to alter its behaviour when its internal state changes
- which allows to compose objects into tree structures to represent part-whole hierarchies, lets clients treat individual objects and compositions of objects uniformly.
