haive.core.graph.state_graph.registry¶

State graph registry for managing graph model instances.

This module provides a singleton registry for managing state graph models in the Haive framework.

Classes¶

GraphRegistry

Singleton registry for managing state graph models.

Module Contents¶

class haive.core.graph.state_graph.registry.GraphRegistry¶

Bases: haive.core.registry.base.AbstractRegistry[haive.core.graph.state_graph.models.state_graph_model.GraphModel]

Singleton registry for managing state graph models.

This registry provides centralized management of GraphModel instances, allowing registration, retrieval, and lifecycle management of graph models throughout the application.

Example

>>> registry = GraphRegistry.get_instance()
>>> graph = GraphModel(name="my_graph", id="graph_123")
>>> registry.register(graph)
>>> retrieved = registry.get(None, "my_graph")

Initialize the registry with empty graph collections.

clear()¶

Clear all registered graph models from the registry.

Return type:: None

find_by_id(id)¶

Find a graph model by its unique identifier.

Parameters:: id (str) – The unique identifier of the graph.
Returns:: The graph model if found, None otherwise.
Return type:: Optional[GraphModel]

get(item_type, name)¶

Get a graph model by name.

Parameters:

item_type (Any) – Not used in this implementation.
name (str) – The name of the graph to retrieve.

Returns:

The graph model if found, None otherwise.

Return type:

Optional[GraphModel]

get_all(item_type)¶

Get all registered graph models.

Parameters:: item_type (Any) – Not used in this implementation.
Returns:: Dictionary of all graph models by name.
Return type:: Dict[str, GraphModel]

classmethod get_instance()¶

Get the singleton instance of the registry.

Returns:: The singleton instance.
Return type:: GraphRegistry

list(item_type)¶

List all registered graph names.

Parameters:: item_type (Any) – Not used in this implementation.
Returns:: List of all graph names.
Return type:: List[str]

register(item)¶

Parameters:: item (haive.core.graph.state_graph.models.state_graph_model.GraphModel) – The GraphModel instance to register.
Returns:: The registered graph model.
Return type:: GraphModel
