Node Module

Defines the abstract base Node class for graph-based structures. Each Node is assigned a unique identifier via an external IdGenerator. The class provides an interface for managing execution state and generating DOT graph representations using Jinja2 templates.

Class: Node

• Attributes

  • id: int: A unique identifier assigned to each instance upon initialization.

• Methods

  • get_id

    • returns: int, The unique node ID

    Retrieves the unique identifier of the node.

  • generate_stack_frame

    • exec_id: int, The ID of the execution context.
    • returns: None

    Initializes a new state frame for a specific execution context. Designed to be overridden in subclasses that use execution state.

  • delete_stack_frame

    • exec_id: int, The ID of the execution context.
    • returns: None

    Deletes the state frame for a specific execution context. Designed to be overridden in subclasses that use execution state.

  • generate_dot

    • nodes: list[str], A list to append DOT node definitions to.
    • edges: list[str], A list to append DOT edges definitions to.
    • visited: set[str], A set of already visited node IDs to avoid duplicates or recursion.
    • template: list[str], A Jinja2 template used to format the node's DOT representation.
    • returns: None

    Generates the DOT graph representation for this node and its relationships. Must be implemented in subclasses.
