Class Clazz

java.lang.Object

com.landawn.abacus.util.Clazz

public final class Clazz
extends Object

It's designed to provide a convenient way to parameterized the generic type (e.g. List.<String>class).
But the returned Class by all the methods doesn't have the actual parameterized type informations. For example:

 
 List<String> clazz = Clazz.ofList(String.class);
 // clazz doesn't have the actual type parameters information. 
 // you won't be able to get type parameter  String by: cls.getTypeParameters();
 // To save the real type parameters: you need to either:
 Type<List<String>> type = Type.of("List<String>"); // or Type.ofList(String.class)
 
 // Or
 Type<List<String>> type = new TypeReference<List<String>>() {}.type();
