Detailed Description

template<typename PointerType>
class Teuchos::Handle< PointerType >

Generic templated handle class.

In writing derived types, it is usually simplest to use the TEUCHOS_HANDLE_CTORS macro to generate boilerplate constructor code.

There are two modes of construction: construction from an existing RefCountPtr,

 RefCountPtr<Base> r = rcp(new Derived(blahblah));
 Handle<Base> h = r;

and construction from a raw pointer,

 Handle<Base> h = new Derived(blahblah);

The second form makes the code slightly cleaner. Note that to use this second form, it is necessary that Derived implement the Handleable interface; this is necessary to avoid any implicit conversions from raw pointers to smart pointers.

Note that the first form must be used whenever the object being handled has been allocated on the stack.

Definition at line 126 of file Teuchos_Handle.hpp.

template<typename PointerType> Teuchos::Handle< PointerType >::Handle (  const RefCountPtr< PointerType > &  smartPtr  )  [inline]

Construct with an existing RefCountPtr. Definition at line 129 of file Teuchos_Handle.hpp.

template<typename PointerType> Teuchos::Handle< PointerType >::Handle (  Handleable< PointerType > *  rawPtr  )  [inline, explicit]

Construct with a raw pointer to a Handleable. This will make a call to rcp() internally, thus removing that call from the user interface. Definition at line 140 of file Teuchos_Handle.hpp.
