public static TypeCache.TypeCollection GetTypesDerivedFrom();

Declaration

public static TypeCache.TypeCollection GetTypesDerivedFrom(Type parentType);

Declaration

public static TypeCache.TypeCollection GetTypesDerivedFrom(string assemblyName);

Declaration

public static TypeCache.TypeCollection GetTypesDerivedFrom(Type parentType, string assemblyName);

Parameters

parentType Type of a class or interface.
assemblyName Optional assembly name.

Returns

TypeCollection Returns an unordered collection of derived types. If assemblyName is specified, returns only types defined in this assembly.

Description

Retrieves an unordered collection of types derived from the T type.

This method provides fast access to all classes loaded from a given assembly or all Unity domain assemblies, which are derived from a specific class or implement a specific interface. Base class or interface can be a generic. The order of results is undefined.

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. The order of types in the collection is undefined.
