Detailed Description

template<class T, class Callbacks = CSafeStatic_Callbacks<T>>
class CSafeStatic< T, Callbacks >

CSafeStatic<>::

For on-demand object access, both non-CObject and CObject based. Create the variable of type "T" on the first access. The default implementation of allocator uses reference counter of CObject class to prevent premature destruction. Should be used only as static object. Otherwise the correct initialization is not guaranteed.

Parameters

T	Type of the variable to be stored.
Callbacks	A class implementing two methods to perform additional initialization and cleanup: void Create(T* ptr) void Cleanup(T* ptr) NOTE: The Cleanup callback must not destroy the object itself, just perform any additional actions.

Constructor & Destructor Documentation

◆ CSafeStatic() [1/4]

template<class T , class Callbacks = CSafeStatic_Callbacks<T>>

CSafeStatic< T, Callbacks >::CSafeStatic ( TLifeSpan life_span = TLifeSpan::GetDefault() )

inline

Constructor.

Parameters

life_span Life span allows to control destruction of objects. Objects with the same life span are destroyed in the order reverse to their creation order.

See also: CSafeStaticLifeSpan

Definition at line 470 of file ncbi_safe_static.hpp.

◆ CSafeStatic() [2/4]

template<class T , class Callbacks = CSafeStatic_Callbacks<T>>

CSafeStatic< T, Callbacks >::CSafeStatic	(	FCreate	create,
		FCleanup	cleanup,
		TLifeSpan	life_span = `TLifeSpan::GetDefault()`
	)

inline

Constructor.

Parameters

init	Callback function to be used to create the stored object.
cleanup	Callback function to be used for additional cleanup.
life_span	Life span allows to control destruction of objects. Objects with the same life span are destroyed in the order reverse to their creation order.
