Class SetExecutor

java.lang.Object

ai.nervemind.app.executor.SetExecutor

All Implemented Interfaces:

NodeExecutor

@Component
public class SetExecutor
extends Object
implements NodeExecutor

Executor for the "set" node type - sets or transforms data values.

Provides data manipulation capabilities including setting new values, transforming existing data, and referencing values from previous node outputs. Commonly used to prepare data for subsequent nodes or restructure output.

Node Parameters

Set node configuration parameters

Parameter	Type	Default	Description
values	Map or JSON String	{}	Key-value pairs to set
keepOnlySet	Boolean	false	If true, output only contains set values (no input passthrough)

Expression Syntax

Values can reference input fields using expression syntax:

• $input.fieldName - Reference a field from input data
• $input.nested.path - Reference nested fields

Example Configuration

{
"values": {
"userName": "$input.user.name",
"status": "processed",
"timestamp": "$input.createdAt"
},
"keepOnlySet": false
}

Output Behavior

• When keepOnlySet=false (default): Input data is merged with new values
• When keepOnlySet=true: Output contains only the explicitly set values

See Also:

• For removing data based on conditions
• For combining data from multiple branches

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").
