Description

Description:
The Component Object pattern aims to encapsulate individual parts of a system into reusable components that can be dynamically composed. This pattern enhances modularity, reduces coupling, and promotes reusability of code. Each component represents a distinct piece of functionality and can be combined with other components to form complex behaviors without tightly binding them together.

Main elements of the Component Object pattern include:

  • Component Interface: Defines the behavior and properties that all components must implement.
  • Concrete Component: Implements the component interface with specific functionality.
  • Component Container: Manages the lifecycle and interactions of components, allowing dynamic composition.
  • Component Factory: Responsible for creating component instances and assembling them as needed.

References:

Acceptance Criteria:

  1. Implement a basic component interface that defines common behaviors.
  2. Create at least two concrete components implementing the component interface with distinct functionalities.
  3. Develop a component container that supports the dynamic composition and management of these components.

Research direction

Start with the Project Contribution Guidelines and the linked Component Object Pattern Example, since no source file or test entry point is named. Done means adding the component interface, two distinct concrete components, and a container supporting their dynamic composition and management.
