Detailed Description

template<typename T>
class rutz::shared_array< T >

A reference-counted smart pointer for arrays.

The array pointed to is deleted when the last shared_array pointing to it is destroyed or reset.

Definition at line 266 of file arrays.h.

Public Types
typedef T	element_type

Constructor & Destructor Documentation

template<typename T> rutz::shared_array< T >::shared_array (  T *  p = 0  )  [inline, explicit]

Construct with the given array pointer. Ownership is now unconditionally transferred to the shared_array. If the shared_array constructor causes an exception, the pointed-to array will be destroyed.
