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: 
 
 Listinvalid input: '&ltString'invalid input: '&gt' 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:
 Typeinvalid input: '&ltList'invalid input: '&ltString'invalid input: '&gt'invalid input: '&gt' type = Type.of("Listinvalid input: '&ltString'invalid input: '&gt'"); // or Type.ofList(String.class)

 // Or
 Typeinvalid input: '&ltList'invalid input: '&ltString'invalid input: '&gt'invalid input: '&gt' type = new TypeReferenceinvalid input: '&ltList'invalid input: '&ltString'invalid input: '&gt'invalid input: '&gt'() {}.type();
