flowgentic.langGraph.execution_wrappers¶

execution_wrappers ¶

LangGraph/AsyncFlow Integration: bridge AsyncFlow tasks and LangChain tools.

Key features: - Define AsyncFlow tasks with @flow.function_task - Expose as LangChain tools via @integration.asyncflow_tool(...)

Each call runs once. Retries and timeouts belong to the model client, to LangGraph's node policies and to the application.

TBD

- block for executing the agents in parallel!¶

Classes:

Name	Description
`AsyncFlowType`	Enum defining the flow_type of AsyncFlow decoration
`ExecutionWrappersLangraph`	Enhanced integration between AsyncFlow WorkflowEngine and LangChain tools.

AsyncFlowType ¶

Bases: Enum

Enum defining the flow_type of AsyncFlow decoration

ExecutionWrappersLangraph ¶

ExecutionWrappersLangraph(flow: WorkflowEngine)

Enhanced integration between AsyncFlow WorkflowEngine and LangChain tools.

Supports both traditional workflow patterns and React agent orchestration with supervisor patterns and parallel execution.

Methods:

Name	Description
`asyncflow`	Unified decorator to register async functions as AsyncFlow tasks with different behaviors.

asyncflow ¶

asyncflow(
	func: Optional[Callable] = None,
	*,
	flow_type: AsyncFlowType = None,
	backend: Optional[str] = None,
	capture_stdio: bool = False,
	tool_description: Optional[str] = None,
) -> Callable

Unified decorator to register async functions as AsyncFlow tasks with different behaviors.

Parameters:

Name	Type	Description	Default
`flow_type`	`AsyncFlowType`	AsyncFlowType enum specifying the decoration behavior: - AGENT_TOOL_AS_FUNCTION: Creates a LangChain tool (with @tool wrapper) - FUNCTION_TASK: Creates a simple asyncflow task (with args, *kwargs) - SERVICE_TASK: Creates a persistent service task - EXECUTION_BLOCK: Creates a block node	`None`
`backend`	`Optional[str]`	Optional named AsyncFlow backend for this task.	`None`
`capture_stdio`	`bool`	Capture task output when supported by AsyncFlow.	`False`
`tool_description`	`Optional[str]`	Description of an AGENT_TOOL_AS_FUNCTION tool; the function's docstring when omitted.	`None`
