# Structural Design Patterns

## Table of Contents

- [Adapter](#adapter)

- [Composite](#composite)

- [Decortor](#decorator)

- [Facade](#facade)

## Adapter 

- Bridge between 2 interfaces (Useful when we work with Legacy code)

### Disadvantages

- No new functionalities

- Multiple Adapters

## Composite 

- Tree structure

- Component

- Leaf

- Composite

### Disadvantages

- Very costly to create more composite impl

- Overly simple

## Decorator 

- Wrapper

- Add functionality or behavior

- Single Responsibility Principle

- Dynamically compose behavior

- Inheritance and Composition

## Disadvantages

- New Class for every feature

- no of objects (more)

- more comples for the clients

## Facade 

- Make API easy 

- Interface not required

- usually a refactoring pattern

## Disadvantages

- Over usage

- Clean up design pattern
