Description

Base class to implement an UNO object supporting weak references, i.e. the object can be held weakly (by a ::com::sun::star::uno::WeakReference) and aggregation, i.e. the object can be aggregated by another (delegator). This implementation copes with reference counting. Upon last release(), the virtual dtor is called.

How to Derive from this Class

Inherit from this class and delegate acquire()/ release() calls. Re-implement XAggregation::queryInterface().

Methods
OWeakAggObject( ) throw( );	Constructor. No delegator set.
virtual void acquire( ) throw( );	If a delegator is set, then the delegators gets acquired. Otherwise call is delegated to base class ::cppu::OWeakObject.
virtual void release( ) throw( );	If a delegator is set, then the delegators gets released. Otherwise call is delegated to base class ::cppu::OWeakObject.
virtual ::com::sun::star::uno::Any queryInterface( const ::com::sun::star::uno::Type & rType ) throw( ::com::sun::star::uno::RuntimeException );
virtual void setDelegator( const ::com::sun::star::uno::Reference< ::com::sun::star::uno::XInterface > & Delegator ) throw( ::com::sun::star::uno::RuntimeException );	Set the delegator. The delegator member reference is a weak reference.
virtual ::com::sun::star::uno::Any queryAggregation( const ::com::sun::star::uno::Type & rType ) throw( ::com::sun::star::uno::RuntimeException );	Called by the delegator or queryInterface. Re-implement this method instead of queryInterface.
