Detailed Description

Base class to implement a UNO object supporting weak references, i.e.

the object can be held weakly (by a css::uno::WeakReference). This implementation copes with reference counting. Upon last release(), the virtual dtor is called.

Derive:
Inherit from this class and delegate acquire()/ release() calls.

Constructor & Destructor Documentation

◆ ~OWeakObject()

virtual cppu::OWeakObject::~OWeakObject ( )
protectedvirtual

Virtual dtor.

Attention
Despite the fact that a RuntimeException is allowed to be thrown, you must not throw any exception upon destruction!

◆ OWeakObject() [1/2]

cppu::OWeakObject::OWeakObject ( )
inline

Default Constructor.

Sets the reference count to zero.

◆ OWeakObject() [2/2]

cppu::OWeakObject::OWeakObject ( const OWeakObject &  )
inline

Dummy copy constructor.

Set the reference count to zero.

Member Function Documentation

◆ acquire()

virtual void cppu::OWeakObject::acquire ( )
virtual

increasing m_refCount
