nodify.context.temporal_context

nodify.context.temporal_context(context: dict | ChainMap | None = None, **context_keys: Any)

Sets a context temporarily (until the context manager is exited).

Parameters:

• context (dict or ChainMap, optional) –

  The context that should be updated temporarily. This could for example be the main context or the context of a specific node class.

  If None, the keys and values are forced on all nodes.

• **context_keys (Any) – The keys and values that should be used for the nodes context.

Examples

Forcing a certain context on all nodes:

>>> from nodes import temporal_context
>>> with temporal_context(lazy=False):
>>>     # If a node class is called here, the computation will be performed
>>>     # immediately and the result returned.

Switching off lazy behavior for workflows:

>>> from nodes import Workflow, temporal_context
>>> with temporal_context(context=Workflow.context, lazy=False):
>>>     # If a workflow is called here, the computation will be performed
>>>     # immediately and the result returned, unless that specific workflow
>>>     # class overwrites the lazy behavior.
