Class SortExecutor

java.lang.Object

ai.nervemind.app.executor.SortExecutor

All Implemented Interfaces:

NodeExecutor

@Component
public class SortExecutor
extends Object
implements NodeExecutor

Executor for the "sort" node type - sorts items in an array.

Orders array elements based on configurable criteria including sort field, direction, and data type. Supports auto-detection of value types for intelligent sorting behavior.

Node Parameters

Sort node configuration parameters

Parameter	Type	Default	Description
inputField	String	"items"	Field containing the array to sort
outputField	String	"sorted"	Field to store sorted results
sortBy	String	null	Field path within each item (null = sort by item value)
direction	String	"asc"	"asc" for ascending, "desc" for descending
sortType	String	auto	"string", "number", or "date" (auto-detects if not specified)
nullsFirst	Boolean	false	true to put null values first

Sort Types

• number - Numeric comparison (parses strings to double)
• string - Case-insensitive alphabetical comparison
• date - ISO date format comparison (YYYY-MM-DD)
• auto - Detects type based on actual values

Output Data

Output keys added by this executor

Key	Type	Description
[outputField]	List	Sorted array
_sortedCount	Integer	Number of items sorted
_sortedBy	String	Field used for sorting
_sortDirection	String	"asc" or "desc"

/** Executor for sorting arrays based on specified criteria. Supports sorting by number, date, and string values with ascending/descending order.

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").
