AppleTransfer SDK class architecture
1. Introduction
This document details the class architecture of the AppleTransfer SDK, designed to facilitate seamless integration of apple transfer functionalities into third-party applications. The architecture provides developers with a simplified, object-oriented interface, enabling efficient interactions with the AppleTransfer system.
2. Class overview
The AppleTransfer SDK is structured around two primary classes: AppleTransferClient and AppleTransaction. These classes provide a comprehensive API for initiating, managing, and tracking apple transfers.
2.1. AppleTransferClient class
The AppleTransferClient class is the gateway for SDK users to interact with the AppleTransfer API, featuring methods supporting asynchronous operations for improved application responsiveness.
-
apiKey(String): Used for authentication with the AppleTransfer system. -
baseUrl(String): The base URL of the AppleTransfer API.
-
async send_apples(recipientSystem, quantity, variety): Initiates an apple transfer to a specified recipient system. -
async check_status(transactionId): Retrieves the status of an apple transfer. -
async cancel_transfer(transactionId): Cancels an ongoing apple transfer. -
async update_transfer(transactionId, quantity, variety): Updates the details of an existing apple transfer.
2.2. AppleTransaction class
The AppleTransaction class represents an apple transfer transaction, providing interaction methods for the transaction’s lifecycle, including status checks, cancellation, and updates.
-
transactionId(String): The unique identifier of the apple transfer transaction.
-
async status(): Retrieves the current status of the apple transfer. -
async cancel(): Cancels the apple transfer. -
async update(quantity, variety): Updates the quantity or variety of apples being transferred.
2.3. Supporting classes and patterns
Additional classes and patterns further support the SDK architecture to enhance its functionality and usability:
-
AppleVariety: A class that could represent different varieties of apples, adding depth to the domain model. -
TransferHistory: A class for tracking the history of transactions, useful for auditing and troubleshooting.
Interfaces and abstract classes are introduced to standardize operations across different transaction types, ensuring scalability and extensibility.
3. Design patterns and practices
The SDK utilizes design patterns such as Dependency Injection for flexible configuration and the Factory Pattern for creating instances of AppleTransaction. These patterns contribute to a modular, maintainable architecture.
4. Error handling and validation
Error handling and input validation are integral to the SDK, ensuring developers can manage errors effectively and validate inputs before processing operations.
5. Conclusion
The AppleTransfer SDK class architecture offers developers a structured, intuitive interface for integrating apple transfer functionalities. By leveraging asynchronous operations, error handling, and design patterns, the SDK supports the development of robust, user-friendly applications.
