Introduction

The ReplayHistoryResponse class serves as a Data Transfer Object (DTO) for the FSM (Finite State Machine) transition history API. It structures the response data returned from transition history requests, ensuring that the API provides a consistent format, complete with success indicators, data payloads, informative messages, and error handling. This class is pivotal in promoting clarity and readability in API communication and plays a central role in how clients receive and interpret transition history responses.

Class Properties

Constructor

__construct

public function __construct(
    bool|array $success,
    ?array $data = null,
    ?string $message = null,
    ?string $error = null,
    ?array $details = null,
)

Purpose

The constructor initializes a new instance of the ReplayHistoryResponse class, allowing for both array-based initialization and traditional parameter-based construction.

Parameters

• success (bool|array):

  • A boolean indicating whether the request was successful.
  • Alternatively, this parameter can be an array, allowing for the construction of the DTO using an associative array of attributes.

• data (?array, optional):

  • An optional associative array containing the data returned from the transition history API. Default is an empty array.

• message (?string, optional):

  • An optional string message that provides additional context. Default is an empty string.

• error (?string, optional):

  • An optional error message string. Defaults to null, meaning no errors occurred.

• details (?array, optional):

  • An optional associative array that contains additional details related to the response. Default is null.

Functionality

1. Array-based Initialization:

   • If the first parameter is an array and only one argument is provided, the constructor validates the array structure to ensure it contains the required fields (success, data, message, error, details).
   • If the parameter is valid, it prepares the attributes for the parent Dto class's constructor.

2. Array with Additional Parameters:

   • If the first parameter is an array and additional parameters are passed, the constructor still validates the array and ensures that message has a default value if not specified.

3. Standard Initialization:

   • If success is not an array, the constructor calls the parent constructor directly with parameters packed in an associative array.

This dual approach to initialization ensures that the ReplayHistoryResponse can be instantiated flexibly by both API consumers and system internal processes while ensuring data integrity.

Conclusion

The ReplayHistoryResponse class is an essential component within the FSM transition history response framework. It encapsulates operational outcomes, provides detailed error handling, and structures response data in a reproducible manner, ensuring an improved developer experience through its clear, logical construction. Use this documentation to effectively implement and utilize the ReplayHistoryResponse within your applications.
