Inheritance diagram for INode:

Detailed Description

Abstract interface representing a subscriber node in the event bus system.

INode is the base interface that all subscriber nodes must implement to participate in the event bus. It exposes a single private pure virtual method, append(), which is called exclusively by the Bus when a message is dispatched to this node.

The Bus is declared as a friend class to allow it to invoke append() without exposing it to the rest of the codebase, enforcing a strict encapsulation of the message delivery mechanism.

Note: INode is non-copyable and non-movable.; Direct instantiation is not possible - this class must be subclassed. The concrete implementation is provided by Node.

◆ append()

virtual void append ( const std::shared_ptr< Message > & message )

privatepure virtual

Insert a message into the node's internal message queue.

This method is called exclusively by the Bus when a message matching this node's subscriptions (or a broadcast message) is dispatched. It must be implemented by all concrete subclasses to define how incoming messages are stored or processed.

Parameters

message Shared pointer to the message being delivered.

Note: This method is intentionally private and only accessible to Bus via the friend declaration, preventing external code from injecting messages directly into a node.

Implemented in Node.
