Detailed Description

template<typename Base>
class Teuchos::Handleable< Base >

Class Handleable provides an abstract interface for polymorphic conversion from raw pointers to smart pointers.

Recall from the Teuchos RefCountPtr documentation that one should never create directly a smart pointer from a raw pointer; rather, smart pointers should be created through a call to rcp(). The type of the argument to rcp() must be known at compile time. This makes the syntax

 Handle h = new Derived(); 

impossible with the straightforward implementation in which Handle takes a raw pointer to a Base. In order to preserve this clean syntax, we require any handles supporting this syntax to take a raw pointer to a Handleable<Base>, where Handleable<Base> provides a getRcp() method which returns the result of a call to rcp() on this.
