# Design Patterns used in the project

# Value Object

CollouyBinding is a value object. It's been created, because its constructor arguments always come together. Value object ensures correct types and better interface to retrieve its values than an associative array would be.

# Memento

Colloquy uses Memento design pattern to create an object that knows how to save itself and to control when and why should that object save.

# Strategy

Colloquy implements easy driver customisation by using Strategy design pattern.
