public interface PrimitiveWrapper<B,P>
```
Basic interface for wrapping a primitive.
A PrimitiveSet can be wrapped by a single primitive in order to fulfil a cryptographic task. This is done by the PrimitiveWrapper. Whenever a new primitive type is added to Tink, the user should define a new PrimitiveWrapper and register it by calling com.google.crypto.tink.Registry#registerPrimitiveWrapper.
The primitive wrapper wraps primitives of type B into primitives of type P. Often, these are the same classes, but in some cases they may not be. There can only be one wrapper for each result primitive P (as Tink needs to know how to generate a P), but there may be many wrapping the same B.

Modifier and Type	Method	Description
`java.lang.Class<B>`	`getInputPrimitiveClass()`	Returns the primitive class object of the primitive used to create B.
`java.lang.Class<P>`	`getPrimitiveClass()`	Returns the primitive class object of the primitive managed.

```
P wrap(KeysetHandleInterface keysetHandle,
       PrimitiveWrapper.PrimitiveFactory<B> primitiveFactory)
throws java.security.GeneralSecurityException
```
    Wraps a PrimitiveSet and returns a single instance.
    This method gets called when a new primitive is created.
    
    Throws:
    
    java.security.GeneralSecurityException
  - getPrimitiveClass
```
java.lang.Class<P> getPrimitiveClass()
```
    Returns the primitive class object of the primitive managed. Used for internal management. Should be implemented as return P.class; when implementing a wrapper creating objects of type P.
  - getInputPrimitiveClass
```
java.lang.Class<B> getInputPrimitiveClass()
```
    Returns the primitive class object of the primitive used to create B. Used for internal management. Should be implemented as return B.class;.
