Ptr Class

Members

---

Ptr( )

Default constructor that produces a NULL pointer.

Ptr( const Ptr< Type > & ptr )

Copy constructor.

Arguments

• const Ptr< Type > & ptr - Pointer of the given type.

explicit Ptr( Type * ptr )

Constructor.

Arguments

• Type * ptr - Pointer of the given type.

Type * get( ) const

Returns the internal address.

Return value

Pointer.

int getCounter( ) const

Returns the reference counter.

Return value

Reference counter.

void clear( )

Clears the pointer. This method does not destroy the object.

void destroy( )

Destroys the pointer. This method will also destroy the object in case if there are no more pointers, that point to it.

bool operator bool( )

Checks if the pointer equals zero.

Return value

true if the pointer is not equal to zero; otherwise, false.

Type * operator->( ) const

Performs pointer dereferencing.

Return value

Pointer.

bool operator<( const Ptr<Type> & rhs )

Performs "less than" pointer comparison. Destination pointer < Source pointer.

Arguments

• const Ptr<Type> & rhs - Source pointer.

Return value

true if Destination pointer < Source pointer; otherwise, false.

Ptr<Type> & operator=( const Ptr<Type> & ptr )

Performs pointer assignment. Destination pointer = Source pointer.

Arguments

• const Ptr<Type> & ptr - Source pointer.

Return value

Result.

bool operator>( const Ptr<Type> & rhs )

Performs "greater than" pointer comparison. Destination pointer > Source pointer.

Arguments

• const Ptr<Type> & rhs - Source pointer.

Return value

true if Destination pointer > Source pointer; otherwise, false.
