## Abstractions
### Base Classes
The following base classes in the `MaksIT.Core.Abstractions` namespace provide a foundation for implementing domain, DTO, and Web API models, ensuring consistency and maintainability in application design.
---
##### 1. **`DomainObjectBase`**
###### Summary
Represents the base class for all domain objects in the application.
###### Purpose
- Serves as the foundation for all domain objects.
- Provides a place to include shared logic or properties for domain-level entities in the future.
---
##### 2. **`DomainDocumentBase<T>`**
###### Summary
Represents a base class for domain documents with a unique identifier.
###### Purpose
- Extends `DomainObjectBase` to include an identifier.
- Provides a common structure for domain entities that need unique IDs.
###### Example Usage
```csharp
public class UserDomainDocument : DomainDocumentBase<Guid> {
public UserDomainDocument(Guid id) : base(id) {
}
}
```
---
##### 3. **`DtoObjectBase`**
###### Summary
Represents the base class for all Data Transfer Objects (DTOs).
###### Purpose
- Serves as the foundation for all DTOs.
- Provides a place to include shared logic or properties for DTOs in the future.
---
##### 4. **`DtoDocumentBase<T>`**
###### Summary
Represents a base class for DTOs with a unique identifier.
###### Purpose
- Extends `DtoObjectBase` to include an identifier.
- Provides a common structure for DTOs that need unique IDs.
###### Example Usage
```csharp
public class UserDto : DtoDocumentBase<Guid> {
public required string Name { get; set; }
}
```
---
##### 5. **`RequestModelBase`**
###### Summary
Represents the base class for Web API request models.
###### Purpose
- Serves as a foundation for request models used in Web API endpoints.
- Provides a common structure for request validation or shared properties.
###### Example Usage
```csharp
public class CreateUserRequest : RequestModelBase {
public required string Name { get; set; }
}
```
---
##### 6. **`ResponseModelBase`**
###### Summary
Represents the base class for Web API response models.
###### Purpose
- Serves as a foundation for response models returned by Web API endpoints.
- Provides a common structure for standardizing API responses.
###### Example Usage
```csharp
public class UserResponse : ResponseModelBase {
public required Guid Id { get; set; }
public required string Name { get; set; }
}
```
---
#### Features and Benefits
1. **Consistency**:
- Ensures a uniform structure for domain, DTO, and Web API models.
2. **Extensibility**:
- Base classes can be extended to include shared properties or methods as needed.
3. **Type Safety**:
- Generic identifiers (`T`) ensure type safety for domain documents and DTOs.
4. **Reusability**:
- Common logic or properties can be added to base classes and reused across the application.
---
#### Example End-to-End Usage
```csharp
// Domain Class
public class ProductDomain : DomainDocumentBase<int> {
public ProductDomain(int id) : base(id) { }
public string Name { get; set; } = string.Empty;
}
// DTO Class
public class ProductDto : DtoDocumentBase<int> {
public required string Name { get; set; }
}
// Web API Request Model
public class CreateProductRequest : RequestModelBase {
public required string Name { get; set; }
}
// Web API Response Model
public class ProductResponse : ResponseModelBase {
public required int Id { get; set; }
public required string Name { get; set; }
}
```
---
#### Best Practices
1. **Keep Base Classes Lightweight**:
- Avoid adding unnecessary properties or methods to base classes.
2. **Encapsulation**:
- Use base classes to enforce encapsulation and shared behavior across entities.
3. **Validation**:
- Extend `RequestModelBase` or `ResponseModelBase` to include validation logic if needed.
---
This structure promotes clean code principles, reducing redundancy and improving maintainability across the application layers.
---
### Enumeration
The `Enumeration` class in the `MaksIT.Core.Abstractions` namespace provides a base class for creating strongly-typed enumerations. It enables you to define enumerable constants with additional functionality, such as methods for querying, comparing, and parsing enumerations.
---
#### Features and Benefits
1. **Strongly-Typed Enumerations**:
- Combines the clarity of enums with the extensibility of classes.
- Supports additional fields, methods, or logic as needed.
2. **Reflection Support**:
- Dynamically retrieve all enumeration values with `GetAll`.
3. **Parsing Capabilities**:
- Retrieve enumeration values by ID or display name.
4. **Comparison and Equality**:
- Fully implements equality and comparison operators for use in collections and sorting.
---
#### Example Usage
#### Defining an Enumeration
```csharp
public class MyEnumeration : Enumeration {
public static readonly MyEnumeration Value1 = new(1, "Value One");
public static readonly MyEnumeration Value2 = new(2, "Value Two");
private MyEnumeration(int id, string name) : base(id, name) { }
}
```
#### Retrieving All Values
```csharp
var allValues = Enumeration.GetAll<MyEnumeration>();
allValues.ToList().ForEach(Console.WriteLine);
```
#### Parsing by ID or Name
```csharp
var valueById = Enumeration.FromValue<MyEnumeration>(1);
var valueByName = Enumeration.FromDisplayName<MyEnumeration>("Value One");
Console.WriteLine(valueById); // Output: Value One
Console.WriteLine(valueByName); // Output: Value One
```
#### Comparing Enumeration Values
```csharp
var difference = Enumeration.AbsoluteDifference(MyEnumeration.Value1, MyEnumeration.Value2);
Console.WriteLine($"Absolute Difference: {difference}"); // Output: 1
```
#### Using in Collections
```csharp
var values = new List<MyEnumeration> { MyEnumeration.Value2, MyEnumeration.Value1 };
values.Sort(); // Orders by ID
```
---
#### Best Practices
1. **Extend for Specific Enums**:
- Create specific subclasses for each enumeration type.
2. **Avoid Duplicates**:
- Ensure unique IDs and names for each enumeration value.
3. **Use Reflection Sparingly**:
- Avoid calling `GetAll` in performance-critical paths.
---
The `Enumeration` class provides a powerful alternative to traditional enums, offering flexibility and functionality for scenarios requiring additional metadata or logic.
---
### Extensions
### Guid Extensions
The `GuidExtensions` class provides methods for working with `Guid` values, including converting them to nullable types.
---
#### Features
1. **Convert to Nullable**:

---
#### Example Usage
##### Converting to Nullable
```csharp
Guid id = Guid.NewGuid();
Guid? nullableId = id.ToNullable();
```
---
### Expression Extensions
The `ExpressionExtensions` class provides utility methods for combining and manipulating LINQ expressions. These methods are particularly useful for building dynamic queries in a type-safe manner.
---
#### Features
1. **Combine Expressions**:
- Combine two expressions using logical operators like `AndAlso` and `OrElse`.
2. **Negate Expressions**:
- Negate an expression using the `Not` method.
3. **Batch Processing**:
- Divide a collection into smaller batches for processing.
---
#### Example Usage
##### Combining Expressions
```csharp
Expression<Func<int, bool>> isEven = x => x % 2 == 0;
Expression<Func<int, bool>> isPositive = x => x > 0;
var combined = isEven.AndAlso(isPositive);
var result = combined.Compile()(4); // True
```
##### Negating Expressions
```csharp
Expression<Func<int, bool>> isEven = x => x % 2 == 0;
var notEven = isEven.Not();
var result = notEven.Compile()(3); // True
```
---
### DateTime Extensions
The `DateTimeExtensions` class provides methods for manipulating and querying `DateTime` objects. These methods simplify common date-related operations.
---
#### Features
1. **Add Workdays**:
