# zipios\_ReferenceCount(3)

ReferenceCount is useful to ensure proper handling of the reference count for (objects of) classes handled through a SimpleSmartPointer.

## NAME

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

## Detailed Description

### 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.

## Constructor & Destructor Documentation

### template\<class Type\> zipios::ReferenceCount\< Type \>::ReferenceCount ()` [inline]`

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.

## Member Function Documentation

### 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.

## Friends And Related Function Documentation

### 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.
