Caching Mechanism and Management

A feature that accelerates repeated conversions by storing and retrieving previously computed number-to-word results in an in-memory cache.

Overview

The Caching Mechanism & Management feature leverages an internal Least Recently Used (LRU) cache to store the textual representations of converted numbers. This minimizes redundant computations by reusing cached results when available. Developers can control caching behavior using properties like EnableCaching and CacheSize, and can manually clear the cache with the ClearCache() method.

Key Points

Aspect	Description
In-Memory Caching	The feature uses an LRU cache to store results, reducing conversion time for repeated numerical inputs.
Cache Control	The EnableCaching property allows developers to toggle the caching functionality on or off.
Cache Size Customization	The CacheSize property specifies the maximum number of conversion results to be stored, providing control over memory usage and performance.
Cache Management	The ClearCache() method provides a way to manually clear the cache when needed, ensuring fresh conversion results or freeing memory.

Code Example

// Initialize the humanizer control with caching enabled
var humanizer = new SiticoneHumanizerInt();

// Enable caching to store conversion results
humanizer.EnableCaching = true;

// Set the maximum cache size to 2000 entries
humanizer.CacheSize = 2000;

// Convert a number to cache its result
humanizer.Number = 12345;
Console.WriteLine("Conversion result: " + humanizer.Words);

// Later, clear the cache if needed (for example, after bulk updates)
humanizer.ClearCache();

Best Practices

Practice	Recommendation
Enable Caching for Repeated Use	When your application performs multiple conversions of the same numbers, enable caching to improve performance by reducing redundant computations.
Manage Cache Size Appropriately	Choose a cache size that balances performance benefits and memory usage, considering the typical workload of your application.
Periodically Clear the Cache	If the underlying conversion logic or settings change, clear the cache to ensure that outdated results are not reused.

Code Example

// Example: Dynamically adjusting caching settings based on application load
humanizer.EnableCaching = true;
humanizer.CacheSize = 1000; // Default size

// At peak usage, increase the cache size to improve performance
if (isPeakUsage)
{
    humanizer.CacheSize = 5000;
}

Common Pitfalls

Pitfall	Explanation
Over-Caching	Setting a very high cache size can lead to increased memory usage, potentially affecting overall application performance.
Disabling Caching Unnecessarily	Turning off caching in scenarios with many repeated conversions can result in redundant processing and slower performance.
Stale Cache Data	Failing to clear the cache after configuration changes or when the data becomes outdated may lead to inconsistent results.

Code Example

// Incorrect: Disabling caching in a context where repeated conversions are common can lead to performance issues
humanizer.EnableCaching = false;
humanizer.Number = 67890; // Conversion performed without cache optimization
Console.WriteLine("Conversion without caching: " + humanizer.Words);

Usage Scenarios

Scenario	How It Works
High-Frequency Conversion	In applications where the same numbers are frequently converted (e.g., financial dashboards or reporting tools), caching significantly improves response time.
Bulk Data Processing	When processing large datasets, caching reduces computational overhead by reusing conversion results for repeated values.
Dynamic Content Generation	In systems where conversion results are generated on-the-fly and may be requested repeatedly (such as in interactive educational tools), caching ensures quick responses.

Code Example

// Example: Utilizing caching in a reporting tool with frequent number conversions
humanizer.EnableCaching = true;
humanizer.CacheSize = 3000;

// Process a list of numbers where many values repeat
foreach (var number in numbersToConvert)
{
    humanizer.Number = number;
    AppendToReport($"{number} in words: {humanizer.Words}");
}

Real Life Usage Scenarios

Scenario	Explanation
Financial Reporting Systems	Repeatedly converting account balances or financial figures can be optimized using caching, resulting in faster report generation and improved user experience.
E-Commerce Analytics	In scenarios where product metrics and sales figures are converted to words for display, caching minimizes the processing delay for recurring numbers.
Educational Platforms	Learning tools that convert numbers into words for practice exercises can benefit from caching by quickly providing feedback on repeated inputs.

Code Example

// Example: In an e-commerce application, caching conversion results for recurring price figures
humanizer.EnableCaching = true;
humanizer.CacheSize = 1500;

humanizer.Number = 2999;
Console.WriteLine("Price conversion: " + humanizer.Words);

// Later, when the same number is requested, the cached result is reused for a faster response
humanizer.Number = 2999;
Console.WriteLine("Price conversion (cached): " + humanizer.Words);

Troubleshooting Tips

Tip	Details
Monitor Memory Usage	Keep an eye on the memory consumption when increasing CacheSize to ensure that the application does not suffer from performance degradation.
Validate Cache Clear Operations	Confirm that calling ClearCache() effectively removes old conversion results, especially after configuration or data updates.
Log Cache Hits and Misses	Consider logging cache hit/miss statistics during development to verify that caching is working as expected and that repeated conversions are being served from the cache.

Code Example

// Example: Logging cache-related actions for debugging
humanizer.OnNumbersChanged += (sender, e) =>
{
    // Log that a conversion was successful, indicating a potential cache hit if the same number is requested again
    Console.WriteLine($"Number {e.Number} converted to words: {e.Words}");
};

Review

Aspect	Consideration
Performance Enhancement	Caching provides a significant performance boost in scenarios with frequent repeated conversions by reducing redundant computations.
Memory vs. Speed Trade-Off	Developers must balance the cache size to optimize between faster conversion responses and acceptable memory usage.
Developer Flexibility	With simple property controls and methods, the caching mechanism is easy to integrate and manage, offering flexibility to adjust settings based on application needs.

Summary

Summary Point	Description

            humanizer.OnNumbersChanged += (sender, e) =>

            // Perform a conversion to store the result in cache
            humanizer.Number = 12345;

            Console.WriteLine("Cached conversion: " + humanizer.Words);

            // Clear the cache to force a re-conversion if needed
            humanizer.ClearCache();
            Console.WriteLine("Cache cleared.");

            // Convert again after clearing the cache
            humanizer.Number = 12345;
            Console.WriteLine("Conversion after cache clear: " + humanizer.Words);
        }
