ActDim.Reflectron 1.0.1

ActDim.Reflectron

ActDim.Reflectron is a high-performance .NET reflection engine providing compiled expression-tree property getters, setters, dynamic method callers, and strongly-typed member accessors that eliminate traditional System.Reflection runtime invocation overhead.

Features

• Compiled Expression Tree Accessors: Compile property getters and setters into Func<object, object> and Action<object, object> delegates cached per property.
• Fast Dynamic Method Invocation: Call methods dynamically using compiled delegates (FastMethodCallDelegate, FastDynamicDelegate) rather than expensive MethodInfo.Invoke.
• Expression-Based Member Access: Safely retrieve MemberInfo, PropertyInfo, or MethodInfo using strongly-typed lambda expressions (TypeAccess.GetMemberInfo(() => obj.Property)) instead of dangerous magic strings.
• Generic Type Factory Helpers: Helper utilities for dynamically creating Func and Action generic delegates (TypeAccess.GetFuncType, TypeAccess.GetActionType).
• Zero Configuration Caching: Built-in concurrent thread-safe delegate caches for optimal repeated performance.

Installation

Install via the .NET CLI:

dotnet add package ActDim.Reflectron

Or via Package Manager Console:

Install-Package ActDim.Reflectron

Quick Start Examples

1. Strongly-Typed Member Retrieval

using ActDim.Reflectron;
using System.Reflection;

public class User
{
    public string Name { get; set; }
}

// Retrieve PropertyInfo safely without string literals
MemberInfo member = TypeAccess.GetMemberInfo((User u) => u.Name);
Console.WriteLine(member.Name); // Output: Name

2. Fast Property Setters and Getters

using ActDim.Reflectron;
using System.Reflection;

var user = new User { Name = "Initial" };
PropertyInfo propInfo = typeof(User).GetProperty(nameof(User.Name));

// Obtain or create cached compiled setter
var setter = TypeAccess.GetPropertySetter(propInfo);

// Execute compiled setter (near-native speed)
setter(user, "Updated Name");

Console.WriteLine(user.Name); // Output: Updated Name

3. Fast Dynamic Delegate Calls

using ActDim.Reflectron;
using System.Reflection;

MethodInfo method = typeof(string).GetMethod(nameof(string.ToUpper), System.Type.EmptyTypes);
var fastCaller = FastMethodCallDelegate.Create(method);

object result = fastCaller("hello world", null);
Console.WriteLine(result); // Output: HELLO WORLD
