alib::lang::Placeholder< T > Struct Template Reference

Description:

template<typename T>
struct alib::lang::Placeholder< T >

Templated helper that reserves memory of size and alignment corresponding to type T. Along with that, construction, destruction and reinterpretation casts are given in various ways.

The type is used for class members or (less frequently for local variables), whose construction has to be deferred.

Template Parameters

T	The type to replace.
