The WeakReferenceHelper holds a weak reference to an object.
This object must implement the com::sun::star::uno::XWeak interface. The implementation is thread safe.
|
inline |
Default ctor.
Creates an empty weak reference.
com::sun::star::uno::WeakReferenceHelper::WeakReferenceHelper | ( | const WeakReferenceHelper & | rWeakRef | ) | |
throw | ( | ||||
) |
Copy ctor.
Initialize this reference with the same interface as in rWeakRef.
rWeakRef | another weak ref |
com::sun::star::uno::WeakReferenceHelper::WeakReferenceHelper | ( | const ::com::sun::star::uno::Reference< ::com::sun::star::uno::XInterface > & | xInt | ) | |
throw | ( | ||||
) |
Initialize this reference with the hard interface reference xInt.
If the implementation behind xInt does not support XWeak or XInt is null then this reference will be null.
xInt | another hard interface reference |
com::sun::star::uno::WeakReferenceHelper::~WeakReferenceHelper | ( | ) | ||
throw | ( | |||
) |
Releases this reference.
void com::sun::star::uno::WeakReferenceHelper::clear | ( | ) | ||
throw | ( | |||
) |
Releases this reference.
::com::sun::star::uno::Reference< ::com::sun::star::uno::XInterface > com::sun::star::uno::WeakReferenceHelper::get | ( | ) | const | |
throw | ( | |||
) |
Gets a hard reference to the object.
|
inline |
Gets a hard reference to the object.
WeakReferenceHelper& com::sun::star::uno::WeakReferenceHelper::operator= | ( | const WeakReferenceHelper & | rWeakRef | ) | |
throw | ( | ||||
) |
Releases this reference and takes over rWeakRef.
rWeakRef | another weak ref |
WeakReferenceHelper& com::sun::star::uno::WeakReferenceHelper::operator= | ( | const ::com::sun::star::uno::Reference< ::com::sun::star::uno::XInterface > & | xInt | ) | |
throw | ( | ||||
) |
Releases this reference and takes over hard reference xInt.
If the implementation behind xInt does not support XWeak or XInt is null, then this reference is null.
xInt | another hard reference |
|
inline |
Returns true if both weak refs reference to the same object.
rObj | another weak ref |
