Bridge Design Pattern

The bridge pattern varies the abstraction independently of the implementation, thus decoupling the two in the process.

Problem

Solution

Abstraction

• provide high-level control logic for Client
• rely on the Implementation object to do the actual low-level work

Refined Abstraction (optional)

• provide variants of control logic
• rely on different Implementation methods

Implementation

• declare the interface for all concrete implementations that Abstraction can access

Client

Only interested in working with the Abstraction.
