2. What is PicoContainer?
Is a embeddable Inversion of Control (IoC)
container for components honor the Dependency
Injection pattern.

3. Features
• Lifecycle
• Scoped Containers
• CommandLinePicoContainer
• Caching and Singletons

4. Design Patterns
• Inversion of Control (IoC).
• Separation of Concerns (SoC)
• Separation of API (or Interface) from Implementation
• Aspect Oriented Programming (AOP)
• Component Oriented Programming (COP)
• Declarative Programming
• Event Based Programming (EBP)

5. IoC
A key part of what makes
a framework different to a
library

6. Dependency Injection
Giving an object its instance variables

7. History

8. Dependency Injection Types
• Constructor Injection
• Setter Injection
• Annotated Field Injection
• Annotated Method Injection
• Typed Field Injection
• Named Field/Method Injection

9. Constructor Injection
• Type 3
• As much as possible, to create valid objects at construction
time
• What it means to create a valid object in an obvious place
• You to clearly hide any fields that are immutable by simply not
providing a setter

10. Setter Injection
• Type 2
• If you have a lot of constructor parameters
• If you have multiple ways to construct a valid object
• If you have simple parameters such as strings
