A package with classes that treated as if it is a part of the language. Such Classes are universal and have no main purpose. Deep in the code, It so helpful. Specially if it designed that anyone is relying on them.


Clazz

GitHub Javadoc

---

The class instance is a main data source when it comes to reflection. But it is constant, and the user can't specify what he exactly wants. So, when it comes to that, Clazzes may be the saver. A Clazz is simple yet powerful instance. It holds information about what is the class it represents, what way should we respond to that class and what are the component types desired to be.

• of(Class, Class, Clazz...) is the main method getting a clazz to represent the needs of the caller. It accepts what is the treatment (or the “family”) should be by reading that clazz. And accepts what is the class that the returned clazz should represent (for example, used for constructing a new instance). And accepts the component types of the clazz that should be respected.
  
  

    //the clazz below should be treated as if it was a Set. and if
    //a new instance needed it should be a new instance of ArrayList.
    //And anyone should really respect that this clazz only allow
    //String elements. 
    Clazz klazz = Clazz.of(
        Set.class,
        ArrayList.class,
        Clazz.of(String.class)
    );
  

  
  

• ofa(...) is the default method to resolve the array classes if no component types provided. It is used by the method Clazz.of() when that method detects such condition.
  

• ofi(...) is a shortcut for the method Clazz.of(). It accepts an instance and return a clazz suitable for that instance; Null will return a class representing the class Void.
  

• ofz(...) is also a shortcut for the method Clazz.of(). It allows getting a clazz with part of the data changed than the clazz given to it such as the family or the component types.

DejaVu

GitHub Javadoc

---

The class DejaVu is a representation class that can't be instanced nor inherited. It represents a dejaVu action. It could be used as the family of a Clazz, so it tells the method to treat it as a DejaVu.



Empty

GitHub Javadoc

---

The class Empty is a representation class that can't be instanced nor inherited. It represents the emptiness. It could be used as the family of a Clazz, so it tells the method to ignore the object as if it was not there.



Recurse

GitHub Javadoc

---

The class Recurse is a representation class that can't be instanced nor inherited. It represents recursion. It could be used as the family of a Clazz, so it tells the method that a recursion is happening.
