Public Member Functions¶

ReferenceCount ()
Constructor intializes count to zero. ReferenceCount (const ReferenceCount &src)
Copy-constructor intializes count to zero. const ReferenceCount & operator= (const ReferenceCount &src)
The assignment operator doesn't copy the reference count, it leaves it unchanged.

Friends¶

class SimpleSmartPointer< Type >
SimpleSmartPointer needs to be a friend to invoke the private ref() and unref() methods. class SimpleSmartPointer< const Type >
class FileEntry
Type also needs to be a friend to invoke the private ref() and unref() methods, in case Type doesn't want to inherit ReferenceCount and thus needs to invoke ref() and unref() through forwarding member functions. class Bogus

template<class Type>¶

class zipios::ReferenceCount< Type >" ReferenceCount is useful to ensure proper handling of the reference count for (objects of) classes handled through a SimpleSmartPointer.

Subclassing ReferenceCount is all a class needs to become ready for being handled by SimpleSmartPointer. Another way is to add a ReferenceCount member variable to a class and write two methods 'void ref() const' and 'unsigned int unref() const' that invoke the same methods in the ReferenceCount variable.

template<class Type> zipios::ReferenceCount< Type >::ReferenceCount () [inline]¶

Constructor intializes count to zero.

Definition at line 122 of file simplesmartptr.h.

template<class Type> zipios::ReferenceCount< Type >::ReferenceCount (const ReferenceCount< Type > & src) [inline]¶

Copy-constructor intializes count to zero. It doesn't copy it from src.

template<class Type> const ReferenceCount& zipios::ReferenceCount< Type >::operator= (const ReferenceCount< Type > & src) [inline]¶

The assignment operator doesn't copy the reference count, it leaves it unchanged.

template<class Type> friend class FileEntry [friend]¶

Type also needs to be a friend to invoke the private ref() and unref() methods, in case Type doesn't want to inherit ReferenceCount and thus needs to invoke ref() and unref() through forwarding member functions.

template<class Type> friend class SimpleSmartPointer< Type > [friend]¶

SimpleSmartPointer needs to be a friend to invoke the private ref() and unref() methods.
