Constructor & Destructor Documentation

AutoPtrArray() [1/4]

template<class X>

ASSA::AutoPtrArray< X >::AutoPtrArray ( X * p_ = 0 )

inlineexplicit

Construct an AutoPtrArray from a raw pointer.

The word 'explicit' disallows implicit construction of objects, for example in function calls.

Parameters

p_	pointer (defaults to NULL) to assume ownerwhip for.

Definition at line 210 of file AutoPtr.h.

: m_ptr (p_) { /* no-op */ }

References m_ptr.

AutoPtrArray() [2/4]

template<class X>

ASSA::AutoPtrArray< X >::AutoPtrArray ( AutoPtrArray< X > & a_ )

inline

Construct AutoPtrArray from another AutoPtrArray.

Parameters

a_	AutoPtrArray object that gives up its ownership.

Definition at line 216 of file AutoPtr.h.

: m_ptr (a_.release ()) {/* no-op */ }

References AutoPtrArray(), m_ptr, and release().

AutoPtrArray() [3/4]

template<class X>

template<typename T>

ASSA::AutoPtrArray< X >::AutoPtrArray ( AutoPtrArray< T > & a_ )

inline

Construct AutoPtrArray from another AutoPtrArray of different (but related) type.

A pointer to T must be convertible to a pointer to X.

Note

Nonconstant paramenter

Parameters

a_	AutoPtrArray object that is released of ownership.

Definition at line 226 of file AutoPtr.h.

        : m_ptr (a_.release ()) { /* no-op */ }

References AutoPtrArray(), m_ptr, and release().

~AutoPtrArray()

template<class X>

ASSA::AutoPtrArray< X >::~AutoPtrArray ( )

inline

When AutoPtrArray goes out of scope, the object it owns is deleted.

Not owning anything has no effect.

Definition at line 255 of file AutoPtr.h.

                     { 
        if (m_ptr) { 
            delete [] m_ptr; 
        }  
    }

AutoPtrArray() [4/4]

template<class X>

ASSA::AutoPtrArray< X >::AutoPtrArray ( AutoPtrArrayRef< X > ref_ )

inline

Automagic conversions.

These operations convert an AutoPtrArray into/from an AutoPtrArrayRef as needed. This allows on-the-fly conversion between AutoPtrArray of different but related types (parent/child):

AutoPtrArray<Derived> FooReturnsAutoPtrArray () { ... };
 
AutoPtrArray<Base> aptr = FooReturnsAutoPtrArray ();

Definition at line 320 of file AutoPtr.h.

: m_ptr (ref_.m_ptr) { /* no-op */ }
