Glossary

Core Concepts

• Node: A single element in the hierarchical tree structure that can process events and maintain state.
• Protocol: A reusable behavior that nodes can participate in (e.g., Lifecycle, Discovery, Authorization).
• Routing Strategy: Determines how events are propagated through the tree (e.g., Tunneling, Bubbling).
• Geometry: The structure and relationships between nodes in the middleware tree.
• Event: A message that flows through the middleware tree, carrying data and metadata.

Components

• MQTT Connector: A node that provides MQTT protocol integration for pub/sub messaging.
• JWT Authorization: A node that handles JSON Web Token validation and authorization.
• Terminal Component: A node that provides command processing and shell capabilities.

WPF Integration

• XAML Configuration: Declarative syntax for defining middleware tree structure and behavior.
• Visual Tree: The WPF representation of the middleware tree for debugging and monitoring.
• Property Binding: Connection between WPF UI elements and middleware node properties.

Development

• Middleware Pipeline: The sequence of nodes that process an event.
• Event Handler: A function that processes specific types of events.
• Property System: Mechanism for managing and propagating state changes.
• Tree Traversal: The process of visiting nodes in the middleware tree.
