Unity Bridge Pattern: Top Use Cases

The main application scenarios of the Unity bridge pattern include:

1. The bridge pattern can be used when there is a need to separate an abstraction from its implementation, allowing them to vary independently. For example, when there are multiple different graphic objects (such as circles, rectangles, triangles) and multiple drawing methods (such as drawing, filling with color), the bridge pattern can be used to decouple the graphic objects from the drawing methods.
2. The bridge pattern can be used when there is a need to establish a stable connection between the abstract part and the implementation part without creating a fixed binding relationship between them. For example, when there are multiple different databases (such as MySQL, Oracle) and various data access methods (such as JDBC, ORM), the bridge pattern can be used to decouple the databases from the data access methods.
3. The Bridge pattern can be used when a class has two or more independent dimensions of change. For example, when there are multiple types of phones (such as iPhones, Android phones) and multiple types of software (such as games, social media), the Bridge pattern can be used to decouple phones and software.
4. The Bridge pattern can be used when you want to dynamically change the implementation of an object at runtime. For example, when switching between different UI themes (such as dark theme and light theme), the Bridge pattern can be used to decouple the UI theme from the interface object.
