Detailed Description

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

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

Recall from the Teuchos RCP 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

ConstHandle h = new Derived(); 

impossible with the straightforward implementation in which ConstHandle 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 ConstHandleable<Base>, where ConstHandleable<Base> provides a getConstRcp() method which returns the result of a call to rcp() on this.
