Constructor & Destructor Documentation

ReferencePointer::ReferencePointer (    )  [inline, explicit]

Construct a ReferencePointer with no object reference (null pointer).

ReferencePointer::ReferencePointer (  Object *    ptr )  [inline, explicit]

Assign to a specific object.

ReferencePointer::ReferencePointer (  const ReferencePointer &    r )  [inline, explicit]

Light-weight copy with reference counting.

virtual ReferencePointer::~ReferencePointer (    )  [inline, virtual]

Decrement the object's reference count and destroy the object if the count reaches zero.

Member Function Documentation

bool ReferencePointer::__eq__ (  const ReferencePointer &    other )

virtual Object* ReferencePointer::__get__ (    )  [inline, virtual]

bool ReferencePointer::__ne__ (  const ReferencePointer &    other )

void ReferencePointer::_assign_fast (  Object *    ptr )  [inline, protected]

Rebind to a new object, without testing for type compatibility. Use this method only when you know that the pointer you are assignng from has the correct type.

void ReferencePointer::_assign_safe (  Object *    ptr )  [inline, protected]

Rebind to a new object, testing for type compatibility. This method calls _update(), which is overridden in the Pointer<> class to attempt a dynamic cast to the template type and throws an exception if the cast fails.

Object* ReferencePointer::_get (    )  const [inline, protected]

Get the current object pointer.

void ReferencePointer::_release (    )  [inline, protected]

Rebind to null.

virtual void ReferencePointer::_update (  Object *    p )  [inline, protected, virtual]

Change object pointer without reference counting. This method is extended in the Link<> class to test for type compatibility. Reimplemented in Link< T >.

bool ReferencePointer::isNull (    )  const [inline]

Test for null pointer.

bool ReferencePointer::operator! (    )  const [inline]

Test for null pointer.

void* ReferencePointer::operator= (  void *    p )  [inline]

Raw pointer assignment for NULL only.

ReferencePointer& ReferencePointer::operator= (  const ReferencePointer &    r )  [inline]

Light-weight copy with reference counting.

bool ReferencePointer::operator== (  ReferencePointer const &    p )  const [inline]

Comparison with other simdata pointers.

void ReferencePointer::setNull (    )  [inline]

Clear pointer.

bool ReferencePointer::unique (    )  const [inline]

Returns true if this is the only reference to an object.

bool ReferencePointer::valid (    )  const [inline]

Test for non-null pointer.
