TypeCache.GetTypesDerivedFrom

Parameters

Returns

TypeCollection Returns a collection of derived types.

Description

Retrieves a collection of types derived from the T type.

This method provides fast access to all classes loaded in Unity domain assemblies that are derived from a specific class or implement a specific interface. Base class or interface can be a generic.

using UnityEditor;

public class Example
{
    static void ScanAssetPostprocessors()
    {
        var extractedTypes = TypeCache.GetTypesDerivedFrom<AssetPostprocessor>();
        foreach (var editors in extractedTypes)
        {
            //...
        }
    }
}

Or classes which implement a specific interface.

using UnityEditor;

public interface IExampleInterface {}

public class Example
{
    static void ScanInterfaceImplementers()
    {
        var extractedTypes = TypeCache.GetTypesDerivedFrom<IExampleInterface>();
        foreach (var editors in extractedTypes)
        {
            //...
        }
    }
}

Note: The returned TypeCollection is read-only and thread-safe.
