# Components

Component-Based Software Development solutions with Pharo.

## Hydrogen

Simple component model. Each component has a lifecycle with 2 states : Started or Stopped.

A component should be started once it has been initialized and its required ports connected.

### Component

A component is an object which is instance of `HyComponent` or its subclasses.

Each component has a 1 unique provided port and 0 or more required ports.

Component classes define 

### Ports

- Provided port: Allows performing any message. That is the reference of the component.

- Singleton required port: That is an instance variables with setter accessor for connections. Allows sending a message to another component just like objects do.

- Collection required port: That is an instance variable referencing a `HyCollectionPort`. Allows sending a specific message with 0 or more args to a set of components attached to the port.

- ID filtering collection port. That is an instance variable referencing a `HyIdFilteringCollectionPort`. Allows sending a specific message with 0 or more args to a subset of components attached to the port. The subset is defined dynamically based on an id.

### Install Hydrogen

To install Hydrogen evaluate the following in a playground.

```Smalltalk

Metacello new

    baseline: 'HydrogenComponents';

    repository: 'github://bouraqadi/Components';
