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.
