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.

Member Typedef Documentation

template<typename T>

typedef T rutz::shared_array< T >::element_type

The pointed-to type.

Definition at line 270 of file arrays.h.

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.
