Detailed Description

template<class type>
class KStaticDeleter< type >

Little helper class to clean up static objects that are held as pointer.

When the library is unloaded, or the app terminated, all static deleters are destroyed, which in turn destroys those static objects properly. There are some rules which you should accept in the KStaticDeleter managed class:

• Don't rely on the global reference variable in the destructor of the object, it will be '0' at destruction time.
• Don't rely on other KStaticDeleter managed objects in the destructor of the object, because it may be destroyed before your destructor get called. This one can be tricky, because you might not know that you actually use a KStaticDeleter managed class. So try to keep your destructor simple.

A typical use is

 static KStaticDeleter<MyClass> sd;

 MyClass &MyClass::self() {
   if (!_self) { sd.setObject(_self, new MyClass()); }
   return *_self;
 }

Member Function Documentation

template<class type>

virtual void KStaticDeleter< type >::destructObject

(

)

[inline, virtual]

Destructs the object.

This has the same effect as deleting the KStaticDeleter.

Reimplemented from KStaticDeleterBase.

Definition at line 120 of file kstaticdeleter.h.

template<class type>

type* KStaticDeleter< type >::setObject	(	type *&	globalRef,
		type *	obj,
		bool	isArray = false
	)			[inline]

Sets the object to delete and registers the object to be deleted to KGlobal.

If the given object is 0, the former registration is unregistered.

Parameters:

	globalRef	the static pointer where this object is stored This pointer will be reset to 0 after deletion of the object.
	obj	the object to delete
	isArray	tells the destructor to delete an array instead of an object

template<class type>

KDE_DEPRECATED type* KStaticDeleter< type >::setObject	(	type *	obj,
		bool	isArray = false
	)			[inline]

Sets the object to delete and registers the object to be deleted to KGlobal.

If the given object is 0, the former registration is unregistered.

Parameters:

	obj	the object to delete
	isArray	tells the destructor to delete an array instead of an object

Deprecated:

See the other setObject variant.
