Architecture

1. Entities

1.1. Component

Component is an object that can be attached to grid components hierarchy and react to initialize & prepare calls. Components must implement IComponent interface.

1.2. Registry

Subtype of component that can store child components

Note: Grid component is not always something that can be rendered.

2. Grid lifecycle

Step 1: Configuration

• Create & link components & configuration objects

Step 2: Initialization

• Instantiate grid
• Initialize components (see IComponent::initialize)
• Dispatch Grid::EVENT_CREATE

Step 3: Rendering

• Check cached version
• Prepare components (apply something to data provider, sort, filter, processinput, etc. Then dispatch EVENT_PREPARE)
• Reset data provider state
• Render main template
