Detailed Description

template<class interface_type>
class com::sun::star::uno::WeakReference< interface_type >

The WeakReference<> holds a weak reference to an object.

This object must implement the com::sun::star::uno::XWeak interface. The implementation is thread safe.

Template Parameters
interface_typetype of interface

Constructor & Destructor Documentation

template<class interface_type >
com::sun::star::uno::WeakReference< interface_type >::WeakReference ( )
throw (
)
inline

Default ctor.

Creates an empty weak reference.

template<class interface_type >
com::sun::star::uno::WeakReference< interface_type >::WeakReference ( const Reference< interface_type > &  rRef)
throw (
)
inline

Copy ctor.

Initialize this reference with a hard reference.

Parameters
rRefanother hard ref

Member Function Documentation

template<class interface_type >
com::sun::star::uno::WeakReference< interface_type >::operator Reference< interface_type > ( ) const
throw (
)
inline

Gets a hard reference to the object.

Returns
hard reference or null, if the weakly referenced interface has gone
template<class interface_type >
WeakReference& com::sun::star::uno::WeakReference< interface_type >::operator= ( const ::com::sun::star::uno::Reference< interface_type > &  xInt)
throw (
)
inline

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.

Parameters
xIntanother hard reference
Since
UDK 3.2.12
