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) 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.

Derive:

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

Constructor & Destructor Documentation

cppu::OWeakAggObject::OWeakAggObject ( )

inline

Constructor.

No delegator set.

Definition at line 48 of file weakagg.hxx.

cppu::OWeakAggObject::~OWeakAggObject ( )

protectedvirtual

Virtual dtor.

Called when reference count is 0.

Attention:

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

cppu::OWeakAggObject::OWeakAggObject ( const OWeakAggObject & rObj )

private

Member Function Documentation

void cppu::OWeakAggObject::acquire	(	)
throw	(
	)

virtual

If a delegator is set, then the delegators gets acquired.

Otherwise call is delegated to base class cppu::OWeakObject.

Reimplemented from cppu::OWeakObject.

Definition at line 283 of file weak.cxx.

References cppu::OWeakObject::acquire(), x, and xDelegator.

OWeakAggObject& cppu::OWeakAggObject::operator= ( const OWeakAggObject & rObj )

private

Any cppu::OWeakAggObject::queryAggregation ( const css::uno::Type & rType )

virtual

Called by the delegator or queryInterface.

Re-implement this method instead of queryInterface.

See also: queryInterface

Definition at line 310 of file weak.cxx.

References Any, and cppu::queryInterface().

Referenced by cppu::OComponentHelper::queryAggregation(), and queryInterface().

Any cppu::OWeakAggObject::queryInterface ( const css::uno::Type & rType )

virtual

If a delegator is set, then the delegator is queried for the demanded interface.

If the delegator cannot provide the demanded interface, it calls queryAggregation() on its aggregated objects.

Parameters

rType demanded interface type

Returns: demanded type or empty any

See also: queryAggregation.

Reimplemented from cppu::OWeakObject.

Definition at line 303 of file weak.cxx.

References Any, queryAggregation(), x, and xDelegator.

void cppu::OWeakAggObject::release	(	)
throw	(
	)

virtual

If a delegator is set, then the delegators gets released.

Otherwise call is delegated to base class cppu::OWeakObject.

Reimplemented from cppu::OWeakObject.

Definition at line 293 of file weak.cxx.

References cppu::OWeakObject::release(), x, and xDelegator.

void cppu::OWeakAggObject::setDelegator ( const css::uno::Reference< css::uno::XInterface > & Delegator )

virtual

Set the delegator.

The delegator member reference is a weak reference.

Parameters

Delegator the object that delegate its queryInterface to this aggregate.

Definition at line 320 of file weak.cxx.

References xDelegator.
