Node - Uniac

uniac.Node is the base class for dependency references. You don’t subclass Node directly — uniac install generates a Node subclass for every published Service you depend on, and you import the generated class.

from uniac import Node            # base class
from logger import Logger         # generated Node subclass

Construction

Node subclasses take zero arguments:

self.logger = Logger()

You initialize Nodes in your __init__. The framework asserts (via _uniac_validate) that every annotated Node slot is filled with the right type.

Runtime attributes

After load hydrates the spec, each Node instance exposes:

Attribute	Type	Meaning
`.url`	`str` or `None`	Live HTTP URL of the deployed dependency. `None` if accessed before `load()`.
`.name`	`str`	The published Service identifier.

In uniac dev, .url points at the local simulator instance. After uniac deploy, it points at the production endpoint of the dep.

Class-level fields

Each generated Node subclass carries:

Attribute	Meaning
`_uniac_primitive`	The published lib name.
`_uniac_version`	Published version (default `latest`).

These are set by the projection generator; user code does not assign them.
