The WeakReferenceHelper holds a weak reference to an object.
That object must implement the css::uno::XWeak interface.
The WeakReferenceHelper itself is not thread safe, just as Reference itself isn't, but the implementation of the listeners etc. behind it is thread-safe, so multiple threads can have their own WeakReferences to the same XWeak object.

Default ctor.
Creates an empty weak reference.
| com::sun::star::uno::WeakReferenceHelper::WeakReferenceHelper | ( | const WeakReferenceHelper & | rWeakRef | ) |
Copy ctor.
Initialize this reference with the same interface as in rWeakRef.
| rWeakRef | another weak ref |
| com::sun::star::uno::WeakReferenceHelper::WeakReferenceHelper | ( | const css::uno::Reference< css::uno::XInterface > & | xInt | ) |
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 | ( | ) |
Releases this reference.
| void com::sun::star::uno::WeakReferenceHelper::clear | ( | ) |
Releases this reference.
| css::uno::Reference< css::uno::XInterface > com::sun::star::uno::WeakReferenceHelper::get | ( | ) | const |
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 | ) |
Releases this reference and takes over rWeakRef.
| rWeakRef | another weak ref |
| WeakReferenceHelper& com::sun::star::uno::WeakReferenceHelper::operator= | ( | const css::uno::Reference< css::uno::XInterface > & | xInt | ) |
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 |
