Constructor Details

RandomValueStepHelper

public RandomValueStepHelper()

Method Details

getRandomFunctionTypes

protected org.json.simple.JSONObject getRandomFunctionTypes()

Generates a JSON response containing the available random function types.

Iterates through the list of random value functions defined in RandomValueMeta.functions, and constructs a JSON array where each element represents a function type with its code and description. The resulting JSON object contains this array under the key "randomFunctionTypes".

Returns:

a JSONObject containing the available random function types

handleStepAction

protected org.json.simple.JSONObject handleStepAction(String method,
 TransMeta transMeta,
 Map<String,String> queryParams)

Handles step-specific actions for the RandomValue step.

This method overrides BaseStepHelper.handleStepAction(String, TransMeta, Map) to provide RandomValue-specific functionality. Currently, supports:

• "getRandomFunctionTypes" - returns available random function types

Specified by:

handleStepAction in class BaseStepHelper

Parameters:

method - the name of the method to execute (case-sensitive)

transMeta - the transformation metadata (currently unused for this step)

queryParams - query parameters for the action (currently unused for this step)

Returns:

a JSONObject containing either the action result or an error response
