Detailed Description

template<class T>
class owl::TEnvelope< T >

Envelope-letter type of smart pointers.

In this implementation the envelope acts as a smart pointer to a reference-counted internal letter. This allows a lot of flexibility & safety in working with a single object (associated with the letter) being assigned to numerous envelopes in many scopes. An 'A' version is provided for use with arrays.

Use like:

TEnvelope<T> e1 = new T(x,y,x);   // e1 now owns a T in a letter
e1->Func();                       // invokes Func() on the new T
Func(*e1);                        // passing a T& or a T this way
TEnvelope<T> e2 = e1;             // e2 safely shares the letter with e1
 
TAEnvelope<T> e1 = new T[99];     // e1 now owns T[] in a letter
e1[i].Func();                     // invokes Func() on a T element
Func(e1[i]);                      // passing a T& or a T this way
TAEnvelope<T> e2 = e1;            // e2 safely shares the letter with e1
