Project Design- old version for hw8

This project is a photo editing and management system, which includes key components such as PhotoAlbum, Snapshot, IShape, and ITransformation.

Purpose and Functionality of Each Class and Interface

• IShape Interface: This is an abstract interface that defines the basic properties and behaviors of a shape. All shape classes should implement this interface. It also extends the Cloneable interface, indicating that objects of classes implementing IShape can be cloned.

• ITransformation Interface: This is an abstract interface that defines the basic behaviors of a transformation. All transformation classes should implement this interface.

• Snapshot Class: This class represents a photo snapshot, which contains a set of IShape objects. It can apply ITransformation to change the shapes within it.

• PhotoAlbum Class: This class represents a photo album, which contains a set of Snapshot objects. It can also apply ITransformation to change the snapshots within it.

How the Model Works

In this model, PhotoAlbum is the highest-level component, which contains a set of Snapshot objects. Each Snapshot in turn contains a set of IShape objects. Both PhotoAlbum and Snapshot can apply ITransformation to change their contained shapes.

When a ITransformation is applied, it iterates over all shapes in the PhotoAlbum or Snapshot and transforms each shape.

Choice of Data Representation

This data representation was chosen because it allows us to represent and manipulate shapes and photos in a structured and flexible way. By using a hierarchy of interfaces and classes, we can easily add new types of shapes and transformations without modifying existing code.

Moreover, this design also considers the trade-offs between performance and memory usage. By using lists of IShape and ITransformation in PhotoAlbum and Snapshot, we can efficiently manage a large number of shapes and transformations without creating separate objects for each shape and transformation.

In summary, this design provides a powerful and flexible way to represent and manipulate photos and shapes, while also considering the needs for performance and memory usage.# ShapesPhotoAlbum
