obis-mapper 0.0.1

obis-mapper

obis-mapper is a lightweight .NET library designed to simplify the mapping of values to model properties based on logical names. It supports nested models, handles nullable types, and allows default values to be specified in case of conversion errors.

Features

• Logical Name Mapping: Map values to properties based on logical names with support for tags to distinguish between different mappings.
• Nested Models: Automatically handles nested models through recursion, simplifying complex object structures.
• Default Values: Specify default values for properties in case of conversion errors, ensuring robustness in data mapping.
• Flexible Type Conversion: Supports nullable types and provides customizable conversion handling.

Installation

You can install obis-mapper via NuGet Package Manager or .NET CLI.

NuGet Package Manager

Install-Package obis-mapper

.NET CLI

dotnet add package obis-mapper

Usage

Basic Usage

To start using obis-mapper, annotate your model properties with the LogicalNameMappingAttribute and optionally the NestedModelAttribute for nested models.

using ObisMapper;

public class SimpleModel
{
    [LogicalNameMapping("1.1.1.1")] 
    public int FirstNumericData { get; set; }

    [LogicalNameMapping("1.1.1.2")] 
    public int SecondNumericData { get; set; }

    [LogicalNameMapping("1.1.2.1")] 
    public string FirstStringData { get; set; }

    [LogicalNameMapping("1.1.2.2")] 
    public string SecondStringData { get; set; }
}

Mapping Values

Use the FillObisModel extension method to map values to your model based on logical names.

var model = new SimpleModel();
model.FillObisModel("1.1.1.1", 100);
model.FillObisModel("1.1.2.1", "Example");

Nested Models

For nested models, use the NestedModelAttribute.

public class ComplexModel
{
    [NestedModel]
    public SimpleModel Nested { get; set; }

    [LogicalNameMapping("2.1.1.1")] 
    public double SomeData { get; set; }
}

var complexModel = new ComplexModel();
complexModel.FillObisModel("1.1.1.1", 100);

Handling Conversion Errors and Default Values

You can specify a default value in the LogicalNameMappingAttribute to handle cases where conversion fails.

public class ModelWithDefaults
{
    [LogicalNameMapping("1.1.1.1", DefaultValue = 42)] 
    public int ValueWithDefault { get; set; }
}

var model = new ModelWithDefaults();
model.FillObisModel("1.1.1.1", "InvalidValue");

In this example, ValueWithDefault will be set to 42 if the provided value is invalid.
