Class ManualTriggerExecutor

java.lang.Object

ai.nervemind.app.executor.ManualTriggerExecutor

All Implemented Interfaces:

NodeExecutor

@Component
public class ManualTriggerExecutor
extends Object
implements NodeExecutor

Executor for the "manualTrigger" node type - initiates workflow execution on demand.

The Manual Trigger is the simplest trigger type, allowing users to start workflow execution through the UI "Run" button or API calls. It serves as the entry point for workflows that don't require automated scheduling or external event triggers.

Trigger Flow

  User clicks "Run" → ExecutionService → ManualTriggerExecutor → Downstream nodes

Output Data

Output keys added by this executor

Key	Type	Description
triggeredAt	String	ISO timestamp when execution started
triggerType	String	Always "manual" for this trigger

Input Data Passthrough

Any input data provided when starting the execution (e.g., via API) is merged with the trigger outputs and passed to downstream nodes.

See Also:

• For time-based automated execution
• For HTTP request-triggered execution
• For file system event-triggered execution

Method Details

execute

public Map<String,Object> execute(ai.nervemind.common.domain.Node node,
 Map<String,Object> input,
 ExecutionService.ExecutionContext context)

Description copied from interface: NodeExecutor

Executes the business logic for this node type.

Specified by:

execute in interface NodeExecutor

Parameters:

node - The node definition containing parameters and configuration. Use Node.parameters() to access user settings.

input - Combined output from all upstream nodes that connected to this node. For simple flows, this contains the direct predecessor's output. For merge nodes, it contains combined data.

context - Verification context providing access to workflow-scoped services, logger, and execution metadata.

Returns:

A Map containing the results of this node's execution. Keys in this map become available variables for downstream nodes.
Note: Returning null is treated as an empty map.

getNodeType

public String getNodeType()

Description copied from interface: NodeExecutor

Unique identifier for the node type this executor handles. This must match the 'type' field in the JSON definition of the node.

Specified by:

getNodeType in interface NodeExecutor

Returns:

The unique type string (e.g., "httpRequest", "llmChat").
