GetAsync & Get: Power Up Your Data Retrieval in Buzruk.GenericRepository

This section dives deep into the GetAsync and Get methods, your weapons of choice for retrieving entities in Buzruk.GenericRepository. We'll explore their functionalities, usage scenarios, comparisons, and best practices to empower you with efficient data access.

This comprehensive guide empowers you to master the GetAsync and Get methods within Buzruk.GenericRepository. We'll delve into their functionalities, explore various usage scenarios with different parameters, and provide examples to illustrate their power.

Unveiling the Power of GetAsync (Asynchronous):

• Champion of Responsiveness: GetAsync shines in asynchronous operations. It retrieves an entity by its ID without blocking the UI thread, keeping your applications responsive and snappy. This is particularly valuable for user interfaces where you want to avoid freezing while data is fetched.

Example: Asynchronously Retrieving a Product

// Assuming you have an instance of the repository (`repository`)
// and a product ID (`123`)

Task<Product> productTask = repository.GetAsync<Product>(123);

// Use await to get the actual product object
Product product = await productTask;

if (product != null)
{
    Console.WriteLine($"Product Name: {product.Name}");
}
else
{
    Console.WriteLine("Product not found.");
}

GetAsync in Action:

• Ideal for scenarios where immediate data access isn't crucial, but maintaining a responsive UI is essential.
• Applications with user interactions that could be interrupted by synchronous data retrieval benefit greatly from GetAsync.

Understanding Get (Synchronous):

• Speedy Retrieval: Get excels in synchronous data retrieval. It fetches an entity by its ID in a single operation, making it a good choice when you need the data immediately and UI responsiveness isn't a major concern.

Example: Synchronously Retrieving a Product

// Assuming you have an instance of the repository (`repository`)
// and a product ID (`123`)

Product product = repository.Get<Product>(123);

if (product != null)
{
    Console.WriteLine($"Product Name: {product.Name}");
}
else
{
    Console.WriteLine("Product not found.");
}

Get on the Battlefield

• Perfect for background tasks or processes where responsiveness isn't a priority.
• If you need the data immediately for further processing or decision-making within the same code block, Get might be a suitable choice.

Choosing Your Champion: GetAsync vs. Get

Here's a quick comparison to help you decide:

Pro Tips for Effective Usage

• Embrace Asynchronous Operations: In most modern applications, GetAsync is the recommended approach due to its responsiveness benefits.
• Consider UI Impact: If user interaction might be affected by a data retrieval block, prioritize GetAsync.
• Network Latency Matters: In high-latency network environments, GetAsync can outperform Get due to its non-blocking nature.
• Error Handling: Implement proper error handling mechanisms to gracefully handle cases where the entity might not be found.

Remember: Both GetAsync and Get offer valuable functionalities for retrieving entities. By understanding their strengths, weaknesses, and use cases, you can make informed decisions to optimize your data access strategy in Buzruk.GenericRepository.

Understanding GetAsync (Asynchronous) and Get (Synchronous)

• Core Functionality: Both methods serve the same purpose: retrieving an entity by its ID.
  • GetAsync operates asynchronously, excelling in responsiveness for UI-centric applications.
  • Get works synchronously, fetching data in a single operation, making it suitable for background tasks.

Exploring the Powerhouse Parameters

Both methods offer a plethora of optional parameters that significantly enhance data retrieval capabilities. Here's a breakdown of the key ones:

1. Predicates (Expression<Func<T, bool>>):
   • Function: Filter entities based on specific criteria.
   • Usage: Pass a lambda expression that evaluates to true for entities you want to retrieve.

Example: Get Products with Price Greater Than $100 (Async):

Task<Product> productTask = repository.GetAsync<Product>(
    predicate: p => p.Price > 100
);

// Await the task to get the product
Product product = await productTask;

2. orderBy (Expression<Func<T, object>>) and thenBy (Expression<Func<T, object>>):
   • Function: Order retrieved entities based on one or more properties.
   • Usage: Pass a lambda expression specifying the property for sorting (ascending order by default). Use thenBy for chained sorting (optional).

Example: Get Top 3 Products Ordered by Price (Descending) with thenBy for Name (Async):

Task<List<Product>> productsTask = repository.GetAsync<Product>(
    orderBy: p => p.Price descending,
    thenBy: p => p.Name
).Take(3); // Limit to top 3 products

List<Product> products = await productsTask;

foreach (var product in products)
{
    Console.WriteLine($"Product: {product.Name}, Price: ${product.Price}");
}

3. includes (Expression<Func<T, object>>[]) and thenInclude (Expression<Func<T, object>>[]):
   • Function: Eagerly load related entities along with the primary entity.
   • Usage: Pass an array of lambda expressions specifying the navigation properties to include. Use thenInclude for nested eager loading (optional).

Example: Get Product with its Category (Async):

Task<Product> productTask = repository.GetAsync<Product>(
    includes: p => p.Category
);

Product product = await productTask;

if (product != null)
{
    Console.WriteLine($"Product Name: {product.Name}");
    Console.WriteLine($"Category Name: {product.Category.Name}");
}

4. tracking (bool):
   • Function: Controls whether to track entity changes for potential updates (optional, might require repository configuration for UpdateAsync to work).
   • Usage: Set to true to enable change tracking.

Important Note: Refer to your repository's specific documentation for any additional parameters or configuration requirements related to change tracking.

Behavior Without Parameters

• If no parameters are provided, both GetAsync and Get retrieve the entity by its ID only.
• The returned value is a Product object (or your specific entity type) if the entity is found, or null if not found.

Remember

• Prioritize GetAsync for responsive UI-centric applications.
• Choose Get for background tasks or scenarios where immediate data access is critical.
• Leverage predicates for filtering, orderBy/thenBy for sorting, includes/thenInclude for eager loading, and tracking (if supported) for efficient updates.
• Always refer to your repository's documentation for complete parameter details and configuration requirements.

By mastering these advanced functionalities, you can unlock the full potential of GetAsync and Get, enabling you to retrieve and manipulate data with precision and efficiency within Buzruk.GenericRepository.
