Detailed Description

template<typename T, typename PtrT, typename Cleanup = NoCleanup>
class ONE::util::LazyValue< T, PtrT, Cleanup >

a value that will not be created until it is actually used

The value is created the first time get is called. This template holds a Creator that is used to initialize the value. The creator is destroyed after its first use. Lazy instantiation may be circumvented by using this template's PtrT constructor.
By default, lazy values perform no cleanup. However, this behavior may be controlled through the Cleanup policy.

Parameters:

	T	the used type
	PtrT	the pointer type used for T. Usually either T* or SmartPointer<T>.
	Cleanup	the cleanup policy
