Interface IAbstractFactory<T>

Defines a generic factory interface for creating instances of type T.

Namespace: Workspace.XBR.Xperiflow.Utilities

Assembly: Xperiflow.dll

Declaration

public interface IAbstractFactory<T>

Examples

Basic factory implementation:

// Create a factory for database connections
IAbstractFactory connectionFactory = new AbstractFactory(
    () => new SqlConnection("Data Source=server;Initial Catalog=db;")
);

// Use the factory to create connections
using var connection = connectionFactory.Create();
connection.Open();

Advanced factory with dependency injection:

// Create a factory for complex objects with dependencies
IAbstractFactory processorFactory = new AbstractFactory(
    () => new DataProcessor(
        new DatabaseRepository(connectionString),
        new Logger(),
        new ConfigurationManager()
    )
);

// Create instances as needed
var processor = processorFactory.Create();
var results = processor.ProcessData(inputData);

Remarks

The Workspace.XBR.Xperiflow.Utilities.IAbstractFactory%601 interface provides a standard factory pattern implementation for creating instances of a specific type. This interface is designed to abstract the creation logic, allowing for flexible instantiation strategies including dependency injection, lazy initialization, and complex object construction.

Common Use Cases:

• Dependency InjectionCreating instances with specific dependencies injected

• Lazy InitializationDeferring object creation until needed

• Complex ConstructionObjects requiring multi-step initialization or configuration

• TestabilityEnabling easy mocking and testing of object creation

Implementation Guidelines:

Implementations should be thread-safe if used in concurrent scenarios. The factory should handle any exceptions that occur during object creation and provide meaningful error messages to callers.

Methods

Create()

Creates and returns a new instance of type T.

Declaration

T Create()

Remarks

This method should create a new instance of the specified type using the factory's configured creation logic. Each call to this method typically returns a new instance unless the factory is specifically designed to return singletons or cached instances.

Error Handling:

Implementations should handle any exceptions that occur during object creation and either provide meaningful error messages or allow exceptions to propagate with appropriate context.

Returns

<T>

A new instance of type T

Exceptions

System.InvalidOperationException Thrown when the factory cannot create an instance due to configuration issues
